Do you worry that your hair is thinning? You may wonder what treatments could make a real difference. After all, you wouldn't want to spend money on something that has no chance of helping. Many people also have concerns about their nails. Perhaps they are ridged, or loose, or too thick. Could that be due to nail fungus, or might it have another cause? Most importantly, what could you do about it? In this episode, you'll get a dermatologist's guide to what actually works.

At The People's Pharmacy, we strive to bring you up‑to‑date, rigorously researched insights and conversations about health, medicine, wellness and health policies and health systems.

What Actually Works for Hair and Nail Problems

Dr. Chris Adigun practices both general and cosmetic dermatology. We wanted to ask her about nail problems in particular because they are very common and she maintains a specialty in treating them.

We asked her about the most common nail problems she sees, and she named simple onycholysis (pronounced Oh-nick-oh-LYE-sis). In this condition, the nail begins to lift away from the nail bed. You can identify it because the white area at the fingertip becomes much more extensive than usual. Usually, this is due to exposure to acids such as citrus juices or cleaning solutions. Having your hands in and out of irritants or even water (with or without soap) could lead to onycholysis. An overactive thyroid gland could also lead to onycholysis. To prevent it, try to avoid putting your hands into that sort of liquid. If you must do so, use gloves. And of course, a good hand cream to bolster the skin barrier is a very good idea. If these approaches don't do the trick, especially if there are other symptoms, the doctor may want to test for thyroid function.

Another common problem is allergic contact dermatitis. This could be caused by some of the same irritating substances responsible for onycholysis, but cosmetics are common culprits here. Nail polish and remover, especially nail polish remover, can cause nail problems for some people. If you are one of them, what actually works best might mean finding a less irritating product or, even better, leaving the nails unadorned.

White Spots on Nails

Many people have noticed white spots on their nails. We asked Dr. Adigun what causes these, and she replied that usually they are not worrisome. If you bang your fingertip, as you might if you slammed it in a door or a drawer, the trauma may show up several weeks later as a white spot. (More serious trauma could show up as a dark spot due to blood pooling under the nail; we discussed that with podiatrist Jane Anderson here, but not with Dr. Adigun.)

What About Ridges on the Nails?

Nail ridges are very common, and the ones that run lengthwise along the same axis as the finger are due to aging. Just as our skin develops wrinkles, so do our nails. Consequently, there are no effective treatments.

Nail ridges in children are a different story. They might show up as nails having the texture of sandpaper, or they could be horizontal ridges. Such nails should be seen by a physician, as they could signal an inflammatory condition called lichen planus or even an early sign of psoriasis. While we don't have cures for these conditions, there are effective medications to manage them.

Hangnails and Cuticle Problems

Are you surprised that dermatologists have a fancy term to describe cuticle problems and other trouble affecting the skin around the nail? They call it paronychia (PEAR-oh-nick-ee-ya). If it is caused by an infection, it might be treated with an antimicrobial compound. The best preventative is not to pull, bite or clip off hangnails or rough spots in the cuticles, the skin near the nails. Instead, moisturize and possibly cover the spot with a bandage to remove the temptation while it softens and heals. Instant glue is another simple remedy that really works for hangnails.

Treating Nail Fungus

When the nails are thick, ugly and hard to trim, often people blame nail fungus. But surprisingly, it isn't always the culprit. Mechanical trauma can also create thick nails that are hard to cut. If the nail is thick because it is on a hammer toe so it bumps against the insole of the shoe, antifungal treatment won't help. If a healthcare professional addresses it when it first appears, it may be treatable, but once the body has grown accustomed to producing that thick nail, there may be no effective treatment.

Some nail infections are bacterial as well as fungal. Both may show up together, or the infection may be one or the other. A dermatologist has techniques for diagnosing whether the problem is due to a fungus or to bacteria such as Corynebacterium. Different types of antimicrobial medicines are effective for these infections. Athlete's foot also needs a real diagnosis, since it too might be bacterial rather than fungal in nature. OTC athlete's foot medicines target fungal infections.

Handling Hair Loss

Both men and women experience hair thinning, and no one is pleased about it. The patterns differ, with men noticing a receding hairline and less hair on their temples. Women's hair loss tends to form a Christmas-tree pattern, with the tip of the tree right behind the hairline and the base spreading out over the crown of the head. Women are also prone to hair loss after giving birth to a baby. However, while that may be alarming in the moment, it often corrects itself without treatment over the following months.

Hormonal Treatments for Hair Loss

With men, scientists have identified testosterone metabolites as contributing factors. Drugs such as finasteride (Propecia) or dutasteride block those metabolites and help men regrow hair. Dr. Adigun has begun using these compounds in women who are beyond childbearing. (They are off limits for a person who might become pregnant because they could interfere with the normal development of genitals in a fetus.)

A different hormonal treatment for hair loss is spironolactone. Dermatologists have long used it to treat female pattern hair loss. A review found that spironolactone is an effective and safe treatment option for hair loss" (Cureus, Aug. 16, 2023). Besides boosting scalp hair growth, however, it can also cause itchy scalp, facial hair growth and menstrual problems.

Another approach that actually works for hair loss is minoxidil (Rogaine). Most people are familiar with this as a topical product to be applied twice daily. That might get old after a while. Also, some people react to the product with contact dermatitis, irritation or itching. Low-dose oral minoxidil seems to work as well as topical minoxidil without the irritation. Another possible option which is better than placebo but not as potent as full strength topical minoxidil is rosemary oil. It is less likely to cause itching, however.

For years, anyone who sprained an ankle or twisted a knee got some standard advice: ice it, rest it, wrap it with compression tape and keep it elevated. The acronym for Rest, Ice, Compress and Elevate is RICE. New research shows that following this advice alleviates the pain from the injury in the short term, but it may actually slow healing. What can help you in healing faster from this type of problem? You can hear it directly from a scientist applying cutting-edge research with tendons and rats to getting NBA players back on the court sooner.

At The People's Pharmacy, we strive to bring you up to date, rigorously researched insights and conversations about health, medicine, wellness and health policies and health systems. While these conversations intend to offer insight and perspective, the content is provided solely for informational and educational purposes. Please consult your healthcare provider before making any changes to your medical care or treatment.

Healing Faster from Injuries

Sports medicine expert Dr. Gabe Mirkin coined the acronym RICE in the 1970s. At the time, many physicians and physical therapists embraced this approach to treating injuries. It helped reduce the pain in the immediate term, and it doesn't seem to do any harm over the longer term. It can take quite a while to heal damaged tendons and ligaments, however. Sometimes, that takes even longer than for broken bones to knit.

Eventually, Dr. Mirkin reversed his RICE recommendation. But very few professionals took note. Is there a happy medium between applying RICE and toughing it out by trying to walk a sprained ankle off? Our guest on this episode has been studying the topic of healing faster from injuries and has some concrete advice to offer.

Trying to Fool Mother Nature

Many of the precautions that amateur athletes take are designed to undermine the body's inflammatory response. Yet acute inflammation is exactly how the body tries to heal itself from injury. Ice and ibuprofen are anti-inflammatory, so taking ibuprofen before exercise or icing a sore knee afterwards might be counterproductive.

What Is a Better Approach to Healing Faster?

According to Dr. Keith Baar, immobilizing a joint ("rest") leads quickly to loss of muscle and force. When he put rats on bed rest (listen to learn how), they lost strength rapidly. On the other hand, moving a joint gently helps to reduce swelling by pumping fluid out. This, in turn, is an early step in healing faster. How do you move a joint gently? Dr. Baar has developed his own acronym: 3LD isometrics.

How Do You Practice 3LD Isometrics?

First of all, what does 3LD even mean? It stands for low-load, long-duration isometrics. During isometric exercise, instead of moving a muscle quickly, you hold it in position until it fatigues. Physical therapists recommend isometrics, such as planks or wall squats, to strengthen the muscles around joints.

In low-load long-duration exercises, you provide some support so you are not putting your entire body weight on the joint. In other words, you lessen the load. Rather than moving quickly through the motion, you find the point at which you can feel the tension in the muscle but it doesn't actually hurt. Dr. Baar describes this as ooh instead of ouch. Then you hold that position (with the support, remember) for 30 seconds or so. This is a relatively long duration.

Healing Faster from Sports Injuries

Dr. Baar describes how he helped his nephew, a college-team football linebacker, heal an injured shoulder. Sports injuries are not the only joint problems that could benefit from healing faster with 3LD isometrics. Other common complaints are carpal tunnel syndrome in the wrist or plantar fasciitis in the foot.

Changing the Culture of Treating Injury

Dr. Baar describes his work with a rugby player who injured his hamstring tendon and was able to resume playing much earlier than the surgeon initially anticipated. Baar's team has also worked with a basketball player who ruptured an Achilles tendon last year. Healing faster with 3LD isometric work got him back on the court last year–the only NBA player with such an injury to manage that. As elite athletes learn the advantages of 3LD isometrics, physical therapists will begin offering it to ordinary people who simply want to resume their usual activities sooner.

This week, we get in-depth information on Lp(a), the heart risk no one talks about. You have heard of cholesterol, and you may even know what your cholesterol level is. The compound lipoprotein a may be equally dangerous when it is elevated, but you have probably heard very little about it.

At The People's Pharmacy, we strive to bring you up‑to‑date, rigorously researched insights and conversations about health, medicine, wellness and health policies and health systems. While these conversations intend to offer insight and perspective, the content is provided solely for informational and educational purposes. Please consult your healthcare provider before making any changes to your medical care or treatment.

What Is Lp(a)?

Lipoprotein a, or L-P-little a for short, circulates in the bloodstream, where it picks up and carries cholesterol and oxidized phospholipids. Scientists believe that blood levels are determined mostly by genetics and change very little over the course of our lives. Roughly 20 percent of people have high levels of Lp(a), above 30 ng/dL or 75 nmol/L. The two different figures are because tests use different units to measure the blood concentration, either nanograms per deciliter or nanomols per liter.

While we don't know if Lp(a) has or perhaps once had some important functions, we do know that elevated levels of this chemical is associated with heart disease. People with higher levels are more likely to suffer blood clots and inflammation. That puts them at risk for heart attacks or even strokes. So why hasn't your doctor ordered a blood test to learn your level?

Is Lp(a) the Heart Risk Doctors Can't Treat?

Perhaps doctors have been reluctant to measure or discuss lipoprotein a because they don't have good interventions. That is beginning to change with the development of antisense oligonucleotides, a new category of prescription drugs that can cut levels sharply. The FDA has not yet approved any of these new medications, though. The first of these, pelacarsen, is still in Phase 3 trials needed before the agency can consider the evidence. However, it can bring down lipoprotein a by an estimated 80 percent.

Cardiologists' favorite drugs, statins, do not help Lp(a) levels. In fact, Lp(a) the heart risk rises when people are taking statins to lower their cholesterol. Other cholesterol-lowering drugs such as evolocumab (Repatha) and alirocumab (Praluent) can bring Lp(a) levels down modestly. One really old cholesterol-lowering drug, high-dose niacin, also helps moderate Lp(a). Some people do not tolerate it, however, as it can cause very uncomfortable flushing. So far as we know, no scientists have run studies to see whether niacin reduces the risk of heart attacks and other complications because of its effects on Lp(a).

Other Complications of Lp(a):

Our guest, Dr. Sam Tsimikas, is among the country's leading experts on lipoprotein a. We asked him whether Lp(a) the heart risk factor causes other problems as well. Dr. Tsimikas described heart failure, potentially resulting from a heart attack, as well as peripheral artery disease (PAD), which can make it painful to walk. Lp(a) seems to cause plaque in arteries throughout the body. As a result, it can increase the chance of a stroke. In addition, it contributes to calcification of the heart valves. This condition interferes with their ability to function properly.

What Can We Do If Lp(a) Is Too High?

Dr. Tsimikas runs a unique clinic for cardiology patients with high levels of Lp(a). We asked him how he helps them. One approach is to collect additional information about their level of risk. A coronary calcium score can be a useful indicator. If it is high, he and his patients work to control all the potential risk factors that they can. He discusses the potential benefit of aspirin with them. Because Lp(a) the heart risk factor increases the chance of dangerous blood clots, the anti-clotting activity of aspirin can sometimes be helpful.

Offering dietary advice can be tricky if a patient has high cholesterol as well as elevated Lp(a), since the ideal diets for each are nearly opposite each other. A ketogenic diet tends to raise LDL cholesterol, for example, while it may modestly lower Lp(a). We think by the end of this episode, you'll join us in hoping that scientists can learn a lot more about Lp(a) in the next few years.

A new school year is about to start in many parts of the country. Going back to school can be exciting, but some students may dread it. Perhaps they are struggling with attention deficit hyperactivity disorder, abbreviated ADHD. How can you recognize the symptoms of this problem? What are the most common misconceptions? In short, what are we still getting wrong about ADHD?

When we talk about distractibility, trouble missing deadlines, forgetting where you left your keys, it is easy to relate. Likewise, when we look at kids with wiggles and short attention spans, do we see a child with ADHD or just a normal youngster? What constitutes ADHD? Does everyone have it, or is it an all-or-nothing condition? Expert John Mitchell explains that many people have some symptoms from time to time, but once a person is suffering from enough that it is affecting their ability to function, that is when a yes-or-no ADHD diagnosis is made.

What We Get Wrong About ADHD

One of the most common misconceptions about ADHD is that it primarily affects little boys who can't sit still. While hyperactivity can certainly make a parent or a teacher uncomfortable, the inattention aspect of ADHD could be more disabling in many instances. Moreover, girls too may suffer with ADHD. Though they are less likely to be hyperactive, they can often have difficulty focusing.

Another popular myth about ADHD is that it is a pediatric condition. People think kids grow out of it. What we are beginning to see with more research into ADHD is that some people learn effective coping skills they can use as adults. Nonetheless, many older people who were not recognized as having ADHD when they were children may discover that their impulsivity and lack of follow-through, accompanied by anxiety, depression or migraines perhaps, could be a manifestation of this disorder. Failing to recognize the suffering of neurodivergent adults is another thing we get wrong about ADHD.

How Do You Treat ADHD?

A third misunderstanding about ADHD is that prescribing a stimulant medication is the only treatment necessary. While drugs such as methylphenidate (Concerta, Ritalin) or mixed amphetamines (Adderall) can be really helpful, there is a saying in the ADHD community: the pills don't teach skills. They do allow a person to focus well enough to learn some new skills they will need. Nonpharmacological approaches are important in conjunction with prescription medicine. However, adolescents with ADHD are much less likely to turn to drugs of abuse if they are taking properly prescribed stimulant medicines in the context of a thoughtful treatment plan.

What Is the Role of Emotional Regulation in ADHD?

Pediatric ADHD expert Paul Rosen describes another assumption that we can get wrong about ADHD. A child may appear to be doing fine, bringing home As, getting along well in school. But he describes "duck syndrome," in which you see a duck gliding along the surface of the water. The motion looks effortless, but the duck is paddling like crazy. If it gets into an eddy or a current that's too strong, it can't keep up. These students are working much harder than is apparent and at some point, they encounter demands they can't meet.

How will they respond to that frustration? Trouble with emotional regulation is not always part of the ADHD picture, but it isn't unusual, either. Some kids with ADHD respond pretty much as other youngsters do, but some seem like a super bouncy ball. Their emotions go very high and very low quickly, but they bounce back quickly as well. Still other children may be more like volcanoes. When faced with frustration, they explode, and it may take them many hours to return to baseline.

Focusing on Warm and Fuzzies

Parents sometimes assume that impulsive or explosive behavior is willful, but that is another thing we often get wrong about ADHD. Most of the time, such behavior is emotional. The child wants to be a "good kid" but may not know how to deal with these extreme emotions. Dr. Rosen recommends unconditional positive attention. He suggests that when parents tuck their ADHD children into bed at night, they appreciate one thing the child has done that day and one aspect of the child, separate from the behavior, that is wonderful. This kind of affirmation can help a youngster keep striving for the skills they will need. (In fact, it sounds like a helpful idea for any parent and child, regardless of whether either of them has ADHD.)

Do you suffer with anxiety, depression, or another mental illness? Millions of people do. The usual treatment is a prescription medication. If that doesn't work, the healthcare provider may offer a different one. Diet is certainly not the first topic on the provider's mind. But what if, in addition to appropriate pharmacological treatment, you were able to nourish, protect and energize your brain with your diet? Our guest offers evidence that you can heal your mind with a ketogenic approach to eating.

We need to acknowledge that this approach is quite different from the plant-rich eating pattern advocated by last week's guest, Dr. Will Bulsiewicz. Humans around the world have adopted a wide range of dietary regimens that support health. Listen to Dr. Georgia Ede explain why she thinks a paleo or ketogenic diet is helpful for bolstering brain health.

Can You Heal Your Brain with Food?

We live in stressful times. More than 50 million Americans take prescription antidepressants, and millions more are on anti-anxiety medication. Unfortunately, while these drugs can be life savers, they don't always work as well as we would like. In some cases, antidepressants are only about 10 percent more effective than a placebo.

Dr. Georgia Ede is a psychiatrist who began her investigation into how food affects mental health serendipitously. She was experimenting with her own diet to address some physical health issues. She used a food and symptom journal to discover the best dietary choices for her own health. To her surprise, the "upside-down" diet that helped her feel better physically also improved her sleep and her ability to focus. She started looking into evidence that a paleo or ketogenic diet could benefit people with mental health challenges.

What Is Metabolic Psychiatry?

There is evidence that people consuming unhealthy diets full of fast food or ultra-processed products are more susceptible to symptoms of anxiety (Nutrition Neuroscience, May 19, 2026). On the other hand, people participating in a supervised weight-loss program using either a low-carbohydrate ketogenic diet or a low-fat diet reported improvements in mood (Obesity, Jan. 2007). Those on the ketogenic (Atkins) diet reported less hunger and fewer unpleasant symptoms.

Researchers have also tested a ketogenic diet in people with schizophrenia or bipolar disorder (Psychiatry Research, May 2024). These volunteers also had metabolic disorders, including obesity, which is often an unwanted effect of the ant-psychotic drugs they take to treat their condition. This four-month pilot study saw participants lose weight, reduce insulin resistance and lower their triglycerides. Even more impressive, they had a 32 percent reduction in the Brief Psychiatric Rating Scale. They also reported better sleep and improved life satisfaction.

You may find this recent article from National Geographic of interest: https://www.nationalgeographic.com/health/article/metabolic-psychiatry-keto-diet-brain-science. Unfortunately, it might be behind a paywall.

How Does Food Affect Our Brains?

Most of our body tissues are accustomed to getting energy from glucose, with the help of insulin. However, years of exposure to high levels of these compounds often makes the tissues less sensitive to the effects of insulin. The consequence is that the body–and therefore also the brain–is flooded with high levels of glucose. This exposure can result in the formation of advanced glycation end products in the brain, which can be harmful.

The brain evolved to use either glucose or a flexible mix of glucose and ketones. These are the result of burning fat rather than sugar. A paleo diet will naturally provide more ketones and less glucose. Dr. Ede and colleagues have found that a ketogenic diet can be very helpful even for people with relatively serious mental problems. In one study (which was not placebo-controlled), patients hospitalized with severe persistent mental illness were given a ketogenic diet. Most did well and had significant improvements in their depression and psychosis symptoms (Frontiers in Psychiatry, July 6, 2022).

Is Ketosis Dangerous?

Ketosis itself simply means that you are burning fat as fuel rather than sugar. This can be achieved by following a diet that is high in animal fat, with moderate amounts of animal protein and low amounts of carbohydrate derived from plant foods. Ketosis is not inherently dangerous. However, Dr. Ede urges anyone who wants to heal their brain with diet to ask a healthcare provider to monitor and supervise the process. Prescription drug doses may require adjustment, and people may need support as they adopt a paleo or ketogenic diet. That is why this is not a do-it-yourself approach.

Is Coconut Oil Helpful to Heal Your Brain?

Dr. Ede described the benefits of medium-chain fatty acids produced in digesting fat. You may recall a video from a few years back in which a doctor described helping her husband recover from Alzheimer disease, at least partially, by giving him coconut oil. Some researchers consider Alzheimer disease to be a form of diabetes because the AD brain does not metabolize sugar effectively. Dr. Ede suggested that the benefits may be real, but getting medium-chain fatty acids from the diet rather than be taking coconut oil might be preferable. After Dr. Ede told us about Fran, who overcame significant memory problems by changing to a ketogenic diet, we hope there will be trials on this.

Future Trials on Diet to Heal Your Brain

Dietary trials are notoriously difficult to conduct. People often don't stick to the prescribed diet, and it can be difficult to find an appropriate placebo for comparison. Nonetheless, Dr. Ede is looking forward to results from a large trial of the keto diet for people with schizophrenia or bipolar disorder. This study is being conducted in Australia.

When you decide to grab a bite to eat, do you think about how to feed your gut microbes? Most of us don't. Even if we did, their only means of stating their preferences is somewhat after the fact. Do you end up feeling less than well? Perhaps the denizens of your gut aren't happy. In this episode, we consider how to support your microbiota and whether that can reduce the inflammation that seems to accompany modern life.

Feed Your Gut Right to Fight Inflammation

Dr. Will Bulsiewicz is a gastroenterologist who urges all of us to focus on a healthful fiber-rich plant-strong diet to maintain our microbiome in good shape. He has described his own evolution from a busy medical student relying heavily on processed food products to a whole-food plant-based enthusiast. Eating a wide variety of plants is one of the easiest ways to make sure we are getting the nutrients our gut microbes need.

Why are the trillions of microbes in our large intestine so important? Dr. Bulsiewicz (aka Dr. B.) shares the story of a patient who was overwhelmed by a serious C. diff infection. A course of clindamycin for a skin infection had decimated her normal microbiome and left an open field for C. diff to flourish. Instead of treating her with surgery and even more potent antibiotics, Dr. B. and his colleagues utilized a fecal transplant. She got poop from a healthy person into her colon and left the hospital a few days later in good health herself.

What Is the Link Between the Microbiome and the Immune System?

Inflammation is one of the primary signs that the immune system has gone into action to fight off a perceived foe. There is a close relationship between the gut microbes, the gut barrier and the cells of the immune system. Between 70 and 80 percent of immune system cells are present in the gut (Nutrients, March 9, 2021). There is just one layer of cells in the gut barrier, firmly attached to each other through tight junctions. If those tight junctions break down, pathogens and toxins can get from the gut into the bloodstream and activate the immune system into creating inflammation

Medicines That Harm the Intestinal Barrier

Diets that are high in salt have a negative impact on the integrity of the intestinal barrier (Nutrients, Nov. 25, 2025). In fact, a diet high in salt can reduce the number of Lactobacilli in the gut by 90%. This also affects the permeability of the gut barrier, which can contribute to auto-immune conditions.

When we asked about inflammatory bowel disorders such as Crohn disease or ulcerative colitis, Dr. B. told us he thinks it's a mistake to classify them as auto-immune conditions. Instead, he suggests we should consider these conditions as due to the immune system rejecting the microbiome. Some of them might be initiated and perpetuated by failures in the gut barrier that allow certain organisms or their toxins into systemic circulation.

A number of medications can also harm it, most notably the nonsteroidal anti-inflammatory drugs (NSAIDs). Agents like ibuprofen, naproxen, celecoxib and meloxicam may disrupt the tight junctions that keep the intestinal barrier intact (Gastroenterology, Feb. 2018). In some cases, they may also upset the balance of microbes.

Four Keys to an Anti-Inflammatory Diet

There are several different dietary patterns that allow you to feed your gut and fight inflammation. Good evidence supports a DASH diet, a Mediterranean diet, pescatarian, flexitarian, vegetarian and some vegan diets. We asked Dr. B. to summarize the four features healthful eating patterns share. They include adequate fiber, plenty of polyphenols, healthy fat and fermented foods (think of sauerkraut or kimchi).

Fiber and Flatulence

One drawback of a high-fiber diet is that when microbes in the colon ferment the fiber we can't digest, they produce gases. It has to go somewhere, or it will cause sensations of cramping and bloating. Consequently, fiber is often associated with flatulence. Dr. B. suggests that there may be more gas, and it may be loud, but it shouldn't be stinky. Smelly farts are born of sulfur, which is more common in a diet containing garlic, onions, crucifers like broccoli or cabbage, fish, eggs or meat.

Plant-Powered Plus

We wondered what might be included in the "plus" category when you feed your gut and fight inflammation. Dr. B. offers a few things that you might not expect in a book about diet, but they are related to reducing inflammation. One is to go outside early in the day, every day, to get your circadian rhythm in sync. Another is to maintain your emotional connections with family and friends. Still another, just as important, is to nurture your spiritual core.

In this week's podcast, you get to peek into Dr. B's shopping cart. Are you buying the same vegetables he does? We also get insights on his favorite recipes for grains like farro. And we discuss the effect of coffee on the gut microbes. If you want to feed your gut to encourage certain microbes, remember that consistency is crucial. You can't eat a specific food once and expect it to make a difference. But consuming it several times a week will ultimately add up. We also discuss antidotes for flatulence, if you are interested in that.

Our kidneys do an incredible job filtering our blood every hour of every day. Most of us have two kidneys, and each one has about a million microscopic filters called glomeruli. Unlike the filters in our HVAC system, though, these filters cannot be replaced. But they do their work so well and unobtrusively that most of us don't even think about our kidney function. Although 37 million Americans have kidney trouble, the majority are unaware of their situation. Two tests could reveal how well the kidneys are working. What are they, and how often should you ask about them?

What Are the Two Tests That Reveal Kidney Trouble?

Chronic conditions like high blood pressure and diabetes put a strain on the kidneys. They are very common problems that signal the need for kidney function monitoring. Our guest expert, Dr. Samir Parikh, suggests that all of us should know our numbers. One is derived from the level of creatinine in the blood. This is normally part of a basic metabolic panel. Usually, the panel results will include a number for the estimated glomerular filtration rate (EGFR) calculated from the value for blood creatinine. The other crucial test is a urine test for protein.

Keeping Kidneys Healthy by Staying Properly Hydrated

One of the simplest tactics to keep kidneys healthy is to provide them with enough liquid. We get some fluid from the food we eat, which may be one reason eating fruits and vegetables seems to be good for us. They are full of water! We also need to drink fluid, and plain water is probably the best choice. It would be smart to use thirst as a guideline and make sure to drink when thirsty. We do avoid overdoing water consumption, though, as overloading the kidneys with more fluid than they can handle is dangerous as well.

Medicines That Are Hard on the Kidneys

We mentioned to Dr. Parikh the experience of an older friend, a devoted runner, who discovered that taking ibuprofen after a run reduced the likelihood of having to get up overnight to urinate. He reminded us and our listeners that nonsteroidal anti-inflammatory drugs (NSAIDs) like ibuprofen, naproxen, celecoxib or meloxicam can be hard on the kidneys. That doesn't mean we shouldn't ever take such pain relievers, but perhaps we should try not to make it a habit.

When we asked about other medicines that might be tough on the kidneys, he mentioned PPIs. Proton pump inhibitors such as omeprazole (Prilosec) or esomeprazole (Nexium) are often used to treat heartburn or other digestive symptoms. Regular use can put a strain on the kidneys, although the gastroenterologist recommending the medicine might not warn you of that side effect.

We asked about environmental toxins and learned that heavy metals such as lead or arsenic can harm the kidneys along with other organs. We should make sure that the food we eat and the water we drink are not contaminated with such compounds.

The Possible Benefits of Vitamin B

Dr. Parikh has been studying how the kidneys respond to the B vitamin nicotinamide. The preliminary work he and his colleagues have done so far is promising. However, they have not conducted clinical trials to find out whether the vitamin could help people with early kidney disease.

Because kidneys work so hard, they need a lot of energy to be produced by the mitochondria in their cells. Those mitochondria need NAD+ (nicotinamide adenine dinucleotide) to function at their best. Providing additional nicotinamide appears to help (Nature Reviews. Nephrology, Feb. 2020). One to three grams a day appears to be safe and may be beneficial.

Medications That Can Promote Kidney Health

Some medicines initially developed for other conditions are proving to be helpful in treating kidney disease. In particular, these include diabetes drugs known as SGLT2 inhibitors like dapagliflozin (Farxiga) or empagliflozin (Jardiance). They help slow the decline of kidney function (New England Journal of Medicine, Nov. 4, 2022). GLP-1 agonists may also be familiar because they too are used to treat diabetes. Medications such as semaglutide (Ozempic, Rybelsus, Wegovy) and tirzepatide (Mounjaro, Zepbound) have made headlines as weight loss and diabetes meds, but they also can reduce the risk of kidney failure and other bad outcomes (Lancet. Diabetes & Endocrinology, Jan. 2025). The benefits of these types of drugs should give us hope that we can go from slowing the progression of kidney disease to stopping it in its tracks

Taking Care of Your Kidneys

We asked Dr. Parikh what we should be doing to care for our kidneys and keep them healthy. He urged us once again to know our numbers: most importantly, the numbers from the two tests we discussed, blood creatinine and urine protein. Other numbers that are important for kidney are our blood pressure and, for those with diabetes, HbA1c. In addition to paying attention to all those numbers, we need to embrace a lifestyle that will help keep them where they belong. That means following a heart-healthy diet, staying physically active and getting adequate sleep.

Millions of people suffer with foot trouble. Some have heel pain when they first get out of bed. Others complain of flat feet or bunions. Athlete's foot is very common, though it doesn't always respond as expected to antifungal medications. Speaking of fungus, toenail fungus can be extremely stubborn. What are your feet trying to tell you about what they need? How can you keep them healthy, especially in the summertime?

At The People's Pharmacy, we strive to bring you up to date, rigorously researched insights and conversations about health, medicine, wellness and health policies and health systems.

What Are Your Feet Trying to Tell You?

Most everyone looks forward to summer vacation, but that special time away from the usual routine may pose challenges for your feet. Whether you are hiking in the mountains or running on the beach, you may need to pay attention to your tootsies.

Time at the Beach

Beach time can inspire long walks on the sand, but soft sand could really put a strain on foot muscles that aren't accustomed to it. Our expert guest, podiatrist Jane Andersen DPM, recommends wearing good running shoes for walking long distances on sand. Choosing to walk where the sand is hard-packed when the tide is low can also be helpful.

Possibly the most important but easily overlooked step to protect feet at the beach is to apply sunscreen. The tops of the feet are easily overlooked, but they can burn pretty readily. And if you are planning to spend time sunbathing prone, you might even want to apply sunscreen to the bottoms of your feet. They never see the sun, and walking on sunburned soles could be quite painful.

Protecting Bare Feet

Another consideration at the beach is how you will get from the parking lot or boardwalk to the water. How hot is the sand? If it is hot enough to burn the soles of your feet, you might consider using water sandals.

In general, going barefoot can be risky. Whether you're at the beach, at a campground, in your own backyard or even inside your home, there are potential hazards underfoot. Bits of glass shards, little pieces of wire, tiny pebbles or nails could all cause havoc if they end up embedded in a sole. Protecting your soles by wearing good flip-flops makes a lot of sense. To find a list of flip-flops that provide appropriate arch support as well as sole protection, consult apma.org.

Treating Black Toenails

During this episode, Joe describes a trip to the beach with a long walk. By the time he removed his shoes, his longest toe had a black toenail that was rather painful. Although the pain faded before too long, it took about a year for the dark color to disappear from the nail. Dr. Andersen suggests that it often takes at least nine months to regrow a toenail. She emphasizes that if the nail turns black due to sudden trauma (like dropping something heavy on the toe), a podiatrist should check it out. Sometimes there is a fracture under that discolored nail that requires medical attention for proper healing.

What Is the Story on Flat Feet?

Joe has always had flat feet. Perhaps your feet are flat, too. The condition is pretty common. If Joe gets out of a bathtub or swimming pool and leaves footprints, they are almost oval. There is very little indentation in the center. Other people with higher arches may leave footprints that are nearly C-shaped. Flat feet can benefit from arch support such as orthotic inserts for shoes. High arches can also cause trouble, especially if they are linked to a genetic condition called Charcot-Marie-Tooth. It is a nerve disorder that can also lead to muscle weakness. Consequently, people with high arches may also need podiatric care for their feet to stay comfortable and healthy.

Plantar Fasciitis Is a Pain

The bottoms of your feet have thick connective tissue called fascia that run from the heel to the ball of the foot. Inflammation of this tissue causes pain, typically at the heel but sometimes along the arch. Often, more supportive footgear or special orthotics can help. Getting a shoe with the correct heel drop is important. That is the difference between the height of the shoe at the heel and at the toe. A podiatrist can recommend the most appropriate heel drop for your feet.

Stretching is also useful, particularly pulling the toes toward the knee or stretching the calf in a runner's stretch pose and holding for 30 seconds or so. Rolling the bottom of the foot on a frozen water bottle helps with the stretch at the same time that the cold eases the inflammation. Plantar fasciitis is common and treatable. If left untreated, it may last a long time.

What Can You Do About Stinky Feet?

A couple of listeners shared their experiences with smelly feet, and we asked Dr. Andersen for her opinion. Jan described using a topical erythromycin antibiotic prescription that came as a roll-on. She also got rid of all her stinky shoes and is careful to wear socks that will wick sweat away. Dr. Andersen noted that erythromycin is very effective against a bacterial infection with Corynebacterium minutissimum. This organism glows coral under ultraviolet light and can definitely raise a stink.

Sophia wrote about developing smelly feet after walking around in wet shoes. She finally solved the problem by treating her feet with rubbing alcohol. Dr. Andersen agreed that rubbing alcohol could be helpful. So can soaking the feet in a strong solution of tea. Other tips include cleaning the floor of the shower stall frequently and always wearing socks that wick–not cotton, which absorbs sweat but traps the moisture. Acrylic or wool work better. Another tactic is to alternate shoes; don't wear the same shoes day after day but give them at least a day to dry out.

How Should You Treat a Sprained Ankle?

There has been controversy lately about the standard RICE protocol for a sprain: rest, ice, compression and elevation. Some experts now recommend warmth instead of ice and gentle motion rather than rest immediately after a sprain. Of course, the first step is to ascertain that it is really a sprain and not a fracture. The treatment for those two injuries is completely different and the person suffering the problem may not be able to tell just from the way it feels. An X-ray is prudent.

Bunions and Hammer Toes

If you don't suffer from bunions, you might not know what they are. In a bunion, the bone that supports the big toe (the metatarsal) moves out of alignment and starts to point more towards the midline of the body. To compensate, the rest of the big toe ends up pointing back toward the rest of the foot. This creates a bump on the edge of the foot that might be painful. There doesn't seem to be any clear correlation between the size of the bump and the amount of pain it causes. Bunions seem to be hereditary, at least to some extent. Conservative management entails choosing footwear with a roomy toe box, not pointy-toed shoes. Podiatrists also correct bunions surgically. They can choose from a wide range of surgical approaches.

In hammer toes, one of the toes (typically the second toe) curls over so that the end that would normally face forward points downward. This too can be corrected surgically, but the recovery can be pretty lengthy. A roomy toe box is also a good bet for living with hammer toe.

Taking Care of Your Feet

We asked Dr. Andersen for general advice, and she suggested that one very important consideration is to buy your athletic shoes in person, preferably at a store that caters to athletes. Buy the proper shoes for your activity; in other words, don't try to play pickleball in running shoes. One nationwide chain that does a good job fitting the shoe to the athlete is Fleet Feet. Locally, she recommends Bull City Running.

Are you concerned about your bone health? Do you worry about osteoporosis? According to the CDC, more than 10 million Americans have low bone density that makes them more vulnerable to fractures. For many older people, a fracture can be devastating, reducing mobility and possibly even leading to death. What does the latest medical science tell us about how you can maintain strong bones?

Strong Bones

You may have seen Halloween skeletons or even chewed the meat off a bone that you then dropped on a plate with a clatter. No wonder we usually think of bones as hard, unchanging objects. Dead bones are. But living bones are quite different. Strong bones are constantly undergoing change. Scientists call it remodeling. One set of specialized cells, osteoclasts, breaks bone tissue down and recycles it. Another set, the osteoblasts, builds bone back. Ideally, their activities are in balance. But if the osteoclasts start to get ahead, as they tend to do while we age, that can weaken bone. The result is low bone mass, known as osteopenia, or even serious bone loss called osteoporosis. This puts a person at risk for fractures.

Who Gets Osteoporosis?

Osteoporosis may have been less common a hundred years ago or more, when many people had to do manual labor that put stress on their bones. That helps for strong bones, so today's sedentary lifestyles can undermine bone health. Although we think of osteoporosis as typically affecting postmenopausal women, men can lose bone mass too. Medications may contribute to the risk for bone loss. Steroids such as prednisone or methylprednisolone are especially risky if taken for a long period of time. Androgen deprivation therapy for prostate cancer is a risk factor specifically for men.

Wait–MEN Can Get Osteoporosis?

Q. My husband and I have two friends with significant disability largely due to spinal fractures as a result of osteoporosis. One man was always an avid exerciser, including running marathons. Both men are over six feet tall and have always appeared to be muscular.

My husband is shorter and is physically active, playing tennis and going to the gym regularly. Because of our friends' bone issues, I advised him to request a DXA scan to assess his bone health. The nurse practitioner told him that it was not recommended for men.

I am still concerned that he may be at risk for osteoporosis. Are there medical studies that determine the risk factors for men?

A. The nurse practitioner was mistaken. Men can develop osteoporosis, as your friends discovered.

Many medical guidelines recommend that men over 70 be tested with a DXA scan to assess bone health. If your husband has low testosterone levels or has taken medications such as prednisone, he could be at increased risk for a fracture. He would be prudent to have the assessment.

Diagnosing Osteoporosis

Doctors assess bone mineral density with imaging called dual-energy X-ray absorptiometry, or DEXA for short. Then they compare the results on the scan to the results they would expect from a 30-year-old person. Results more than 2.5 standard deviations from that could result in a diagnosis of osteoporosis. A person who experiences a fracture without trauma, such as falling from standing height, is also suspected and often diagnosed with osteoporosis.

Non-Drug Approaches to Strong Bones:

People who want to keep strong bones need to focus on exercise. High intensity exercise can be helpful, but brisk walking may be enough. Tai chi and yoga are also popular. If you have been diagnosed with osteoporosis, be sure to check in with your doctor before you start a new exercise program. Building balance and core strength without increasing your risk of a fall (and thus a fracture) would be ideal. Our guest expert, Dr. Kendall Moseley, says the jury is still out on technology such as vibrating platforms, weighted vests or vibrating belts. More studies should show how valuable these could be.

Following a diet that supplies adequate protein, vitamin D and calcium is also crucial. If you must take a calcium supplement, calcium citrate may be well tolerated and absorbed.

How Do Doctors Treat Osteoporosis?

Physicians prescribe several different types of medications to help curb bone less and perhaps even build it back. Some of the oldest and least expensive are the bisphosphonates such as alendronate (Fosamax). These slow bone break down and give the osteoblasts a chance to catch up. They can be hard on the digestive tract, though, and they have been associated with a few rare but alarming side effects: jawbone deterioration and atypical thigh bone fracture. Most people seem to do well on them. Doctors generally prescribe them for up to five years.

Did You Forget Evista?

Another type of osteoporosis medicine is called raloxifene (Evista). It is appropriate only for women, because it is an estrogen modulator. It acts like estrogen in the bones and reduces bone loss. In the breast and uterus, it opposes estrogen activity. Raloxifene does double duty in reducing the risk of breast cancer as well as osteoporosis. Like all drugs, though, it has some worrisome side effects. It can increase the risk of blood clots that cause deep vein thromboses and strokes.

What About Prolia?

Denosumab (Prolia) is a monoclonal antibody that also interferes with osteoclasts. That is how it improves bone density. One thing to keep in mind about Prolia is that stopping it requires careful planning and backup medication. Otherwise, a patient can lose all the bone that was built rather quickly and may suffer debilitating fracture.

Do You Need a Sleep Reset?

Why is sleep so important for good health? Our guest is a sleep medicine specialist who uses a metaphor of Disneyland. Crucial maintenance on the theme park happens at night, when there are no visitors. Streets are cleaned, flower beds are weeded, and rides are inspected and, if needed, repaired. None of that can happen while the park is open for business. Our bodies and brains also need time for maintenance and repair, and some of that happens while we are sleeping. When we don't get the rest we need, we may find ourselves at increased risk for diabetes, cardiovascular problems, cancer, cognitive challenges and even premature death.

Unfortunately, anxiety about not sleeping can keep people awake all on its own. How can people break that cycle? We'll also discuss ways that people can get help avoiding screens at night. That is an important part of a sleep reset. Blue light from the screen signals the brain to be alert instead of relax. Scrolling social media can often be emotionally upsetting, which also makes it more difficult to fall asleep.

Is Your Diet Keeping You Awake?

Most of us recognize that a big midnight snack, á la Dagwood Bumstead of the Blondie comic, is probably not conducive to sleeping well. How does nighttime eating affect our circadian rhythm? Are there diets that we should avoid because of their impact on sleep? Dr. Seheult describes a study in which volunteers had their sleep stages monitored closely during the time they were consuming different diets (Obesity, July 2023). When they followed a high-fat, high-sugar diet, it disturbed the pattern of their brain waves during what should have been restorative sleep.

How Do Sleep Problems Affect Eating Habits?

A lot of us are aware that when we are sleep deprived, we are more inclined to become hangry and we may be less discerning about what we eat. A recent study shows that the sleep deprivation can have an effect even if it is fairly mild and short-term. Scientists recruited people who normally sleep seven to eight hours a night and asked them to stay up an extra hour and a half (Annals of Internal Medicine, July 7, 2026). During the six weeks of that part of the experiment, people were less active during the day. They also ate more, so they gained about a pound, on average, during those six weeks. Presumably, disrupting sleep for a longer period of time would result in greater weight gain and metabolic disruption.

Would a Ketogenic Diet Help with a Sleep Reset?

A ketogenic diet, in which the body relies on ketones rather than glucose for energy production, may be helpful. In particular, fasting overnight for at least 14 hours helps the body do what it must during sleep time. To figure out when you should stop eating, identify when you usually start to feel sleepy. That should be your bedtime. Having your last meal of the day about three hours before that will generally offer enough time for digestion so that you don't experience reflux in the middle of the night.

Morning Light and Afternoon Naps

Your sleep reset may depend on getting your own circadian rhythm to synchronize with the rest of the world. That is where early exposure to morning light comes in. It's beginning to feel a bit like The People's Pharmacy is on repeat: get morning light exposure! It sets your system up for feeling awake and alert during the day and starting to feel sleepy as the light fades in the evening. Obviously, this is most helpful for people who work during daylight hours. Those working overnight shifts would have to organize their days differently.

People who have trouble falling asleep may be tempted to take a nap in the afternoon to make up for the lost sleep. That could be a mistake, as it relieves the sleep pressure that helps people fall asleep without trying.

Learning to Fall Asleep

If you interact with parents of very young children, you may have heard of sleep training. People have strong feelings about this, both pro and con. Adults rarely need sleep training, though. What we are more likely to need is "not-sleeping un-training." Too many people approach the bedroom as though it were a stage, and sleep is the performance. No wonder they may develop some performance anxiety about sleeping! Other individuals have learned to associate the bedroom with tossing, turning and watching the clock. Consequently, their bodies tense up instead of relaxing when they get between the sheets. There is no easy quick fix for this problem, but cognitive behavior therapy for insomnia has been proven effective for most people.

How About PM Pain Relievers?

Even though there isn't an easy fix for sleep troubles, many people want one. They reach for the PM pain reliever and hope it will offer them a good night's sleep without a prescription.

The "PM" part of that pain reliever is an old-fashioned antihistamine called diphenhydramine. You might be more familiar with its brand name: Benadryl. You'll also find it in Tylenol PM, Advil PM and all the other PM meds because it tends to make people feel drowsy.

What's wrong with that? To start with, it isn't clear that it remains effective after a week or two. In addition, people with restless leg syndrome often find that it makes their condition worse. Other folks report that diphenhydramine can result in an unpleasant "hangover" the next day, in which they feel drowsy though not asleep for a good part of their waking hours.

What Wakes You Up at Night?

If your sleep problem is waking in the wee hours and having trouble getting back to sleep, you should consider the possibility that you have sleep apnea. The REM sleep of those early morning hours is not as deep as some other sleep stages. Consequently, an alarm signal from your brain saying you haven't taken a breath for 20 or 30 seconds may be more likely to wake you. Sleep apnea may be treated by providing air so that the pressure props the collapsing airway open. We discuss this in greater detail along with a new alternative to a CPAP machine in the podcast for this week.
