Straight Talking Science

What if chronic pain isn’t simply an injury that hasn’t healed, but a nervous system that has become stuck in a cycle of pain?

In this episode of Straight Talking Science, Barry Skillington is joined by Dr. Cormac Mullins, consultant pain specialist at South Infirmary Victoria University Hospital and Cork University Hospital, Clinical Director of PainDoc, and Senior Clinical Lecturer in Pain Medicine at University College Cork (UCC).

Together, they explore what chronic pain actually is, why it affects more than 20% of the global population, and what happens when acute pain becomes persistent.

From chronic back pain, sciatica and fibromyalgia to nerve pain, MRI scans and spinal cord stimulation, Dr. Mullins explains the science behind chronic pain and the evidence-based approaches that can help people manage it.

They discuss why pain can continue long after an injury has healed, how the nervous system can become sensitised, why movement and exercise are important in chronic pain treatment, and why an MRI scan doesn't always explain where pain comes from.

The conversation also explores the connection between chronic pain, sleep, mood and mental health, why women are more commonly represented in pain clinics, the role of multidisciplinary pain management, and the risks of relying too heavily on medication or invasive treatments.

Dr. Mullins explains why opioids are generally not effective for long-term chronic pain, how tolerance and dependence develop, and where treatments such as nerve blocks, epidural injections, acupuncture, spinal cord stimulation and newer procedures may fit into a patient's treatment plan.

Most importantly, this episode looks at how people can move forward with chronic pain without allowing pain to control every part of their lives.

• What chronic pain actually is and how it differs from acute pain
• Why chronic pain can become a disease process in itself
• Chronic back pain, sciatica, fibromyalgia and nerve pain
• The relationship between pain, movement, fear and deconditioning
• Why exercise and movement are important for chronic pain
• MRI scans, spinal degeneration and why imaging doesn't always explain pain
• The dangers of over-interpreting MRI results
• Chronic pain and its connection with anxiety, depression and sleep
• Why women are more commonly affected by chronic pain
• The biopsychosocial approach to pain management
• Peripheral neuropathy and nerve dysfunction
• Pain management and multidisciplinary treatment
• Nerve blocks and epidural steroid injections
• Spinal cord stimulation and emerging treatments
• Opioids, tolerance, dependence and withdrawal
• Complementary therapies including acupuncture
• Evaluating whether a chronic pain treatment is actually working
• The future of chronic pain treatment and new technologies

Chronic pain isn't a sign of weakness, and living with pain doesn't mean giving up on improving your quality of life. Understanding how pain works can be an important part of learning how to manage it.

What if the breakouts, dryness, and wrinkles you've been told to just cover up with makeup are actually signals from your skin that it needs real care, not another 17 step routine? Dr. Doireann O'Leary O'Leary, GP, dermatology specialist, founder of Supplements Made Simple, and health contributor to RTE and Today FM, joins Barry Skillington to cut through the noise and deliver practical, evidence based advice on skin health, common conditions, and what actually works.

From acne and rosacea to psoriasis and eczema, from retinoids and red light therapy to collagen peptides and microneedling, this episode breaks down the science behind healthy skin, hair, and scalp care. Doireann O'Leary explains why less is more, why your skin barrier matters more than you think, and why starting with health instead of chasing beauty trends will give you better results every time. Your skin is your largest organ. It's your first line of defense. It regulates temperature, prevents water loss, and plays a critical role in your immune system. When it's healthy, you don't notice it. When it's not, it affects your confidence, your mental health, and your quality of life.

The problem is modern skincare has become overwhelming. Social media pushes 12 step routines, miracle cures, and products that promise instant results. People start everything at once, disrupt their skin barrier, and end up worse off than when they started. The solution isn't more products. It's understanding what your skin actually needs, building a simple routine that works for you, and giving your body the tools to function properly from the inside out.

Topics covered:

What healthy skin actually is and why you shouldn't notice it

Why less is more and how too many products disrupt your skin barrier

The four core steps: cleanse, moisturize, sunscreen, and add a retinoid

Body skin versus facial skin and why your face ages faster

Sun damage: is it repairable and how sunscreen reverses aging

Common skin conditions: acne, rosacea, eczema, psoriasis, and when to see your GP

Why skin conditions aren't cosmetic and how they impact mental health and confidence

Medical misinformation: navigating Dr. Google, TikTok, and social media advice

Retinoids explained: retinol, tretinoin, adapalene, and why vitamin A is the gold standard

The low slow rule and the sandwich method for starting tretinoin without irritation

Red light therapy: does it work, what wavelength matters, and why devices are worth the investment

Collagen peptides: how they work, marine versus bovine, and why oral collagen signals your skin

Peptides for anti aging: signaling peptides, copper peptides, and Botox in a bottle

Microneedling: how it works, why it's great for acne scars, and why derma rollers at home are a bad idea

Scalp health: why your scalp is skin and how to treat dandruff and hair loss

Hair loss triggers: stress related shedding versus slow thinning and androgenetic alopecia

Why people avoid Regain and why it's the most evidence based treatment for hair loss

Ketoconazole shampoo: how Nizoral reduces DHT and supports scalp health

Oral minoxidil, spironolactone, and finasteride for hair loss in men and women

Perimenopause, menopause, and dramatic changes in hair and skin

Why men need to take care of their skin and why sunscreen is health, not vanity

Red flags in marketing: no nasty chemicals, all natural, plant derived, and why it's meaningless

Affordable brands that work: La Roche Posay, Avene, The Ordinary, and CeraVe

Non product essentials: sleep, nutrition, stress management, movement, and social connection

Why starting with health instead of beauty gives you better results every time

What if the exhaustion, irritability, and overwhelm you've been told to just push through aren't signs of weakness but signals from a nervous system stuck in overdrive? Sinead O'Flynn, registered nurse, nutritional practitioner, and founder of Health4U, joins Barry Skillington to unpack what nervous system regulation actually means, why everyone's suddenly talking about it, and what you can do when stress tips from normal to chronic.

From burnout to breathing techniques, from cortisol and weight gain to long COVID and exercise intolerance, this episode cuts through the social media noise and delivers practical, evidence based strategies for recognizing when your body is screaming for help and how to bring it back to balance. Sinead combines nursing, nutrition, and nutrigenomics to help people with complex health issues, and her approach is clear: your nervous system isn't broken. It's just stuck. And you can unstick it.

Stress is normal. Your body is designed to go into fight or flight and come back down. The problem is modern life keeps you in that heightened state, and over time, chronic stress wreaks havoc on your gut, your hormones, your sleep, your mood, and your ability to function. The solution isn't about being calm all the time. It's about regulation. It's about adaptability. It's about giving your body the tools to respond to stress and recover from it.

Topics covered:

• Sinead's background combining nursing, nutrition, and nutrigenomics for personalized health care
• What nervous system regulation actually is and why social media gets it wrong
• The sympathetic and parasympathetic nervous systems: accelerator and brake
• Why your body is designed to cycle between stress and rest, not stay calm forever
• What chronic stress does to your body over time: gut health, hormones, inflammation, and more
• Burnout: recognizing the signs in mothers, professionals, men, and everyday life
• Why burnout isn't just about work and how suppressed emotions contribute
• Simple tools to start managing stress: slowing down, deep breathing, and giving yourself permission
• The role of diet and lifestyle in supporting your nervous system
• Why stress is normal and when it becomes a problem
• Debunking nervous system myths: can you reset in five minutes? Do cold showers regulate you?
• The truth about probiotics, vagus nerve stimulation, and genetic testing
• Why the vagus nerve is important but not the only thing
• The gut brain axis: how your gut and brain communicate and why both need support
• Cortisol, weight gain, and the hormone connection: why it's never just one thing
• The role of wearables in tracking stress and heart rate variability
• Supplements: when they help, when they're a waste of money, and why they're not forever
• Long COVID, exercise intolerance, and post viral illness
• Why exercise can be harmful if your body isn't ready for it
• Personalized nutrition and the future of nutrigenomics in Ireland
• Mindfulness in schools and teaching kids about food, mental health, and eating properly
• Self assessment: three questions to check if you're stressed or burned out
• The most misunderstood thing about the nervous system: it's about adaptability, not calm
  

Sinead's books:

• When Your Body Overreacts
• When Your Body Whispers Before It Screams

Your nervous system isn't broken. It's stuck. And you can unstick it. Stop chasing quick fixes. Stop believing you can reset in five minutes or that cold showers alone will solve everything. Start slowing down. Start breathing deeply. Start giving yourself permission to prioritize your health without guilt. Eat whole foods that support serotonin production. Support your gut and your brain together. Recognize that irritability, overwhelm, and daily tasks feeling enormous are signs your body is crying out for help. Stress is normal. Burnout is not. Your body whispers long before it screams. Learn to listen. Take control. And remember: regulation isn't about being calm all the time. It's about your body being adaptable enough to rise to the challenge and come back down. That's what nature intended. That's what you deserve.

What if the painful periods, mood swings, and chronic fatigue you've been told to just "deal with" are actually signs of something bigger? Professor Siobhain O'Mahony returns to unpack the hidden connections between your gut microbiome, hormones, and the most misunderstood conditions in women's health.

From endometriosis affecting 1 in 10 women to polycystic ovarian syndrome impacting 1 in 5, these aren't just fertility issues. They're complex, hormone driven syndromes that disrupt metabolism, mood, sleep, and quality of life. Yet diagnosis takes years, treatment is fragmented, and women are left managing symptoms in isolation. Siobhain reveals why your gut bacteria might be recycling too much estrogen, how insulin resistance drives PCOS, and why fiber isn't just for digestion. This is women's health through the lens of cutting edge microbiome science, and it changes everything.

Topics covered:

Why women's pain gets split into the wrong boxes and misdiagnosed for years

Endometriosis: what it is, why it takes 7 to 10 years to diagnose, and the role of visceral pain

Polycystic ovarian syndrome: the insulin resistance connection and why it's not just about fertility

Adenomyosis and fibroids: how they differ from endometriosis and why they matter

The estrobolome: your gut bacteria that recycle estrogen and why that's not always a good thing

How to manipulate your microbiome to support hormone balance and clearance

The role of fiber: psyllium husk, oats, flaxseeds, and why not all fiber is the same

Why your liver and gut health are critical for managing hormone related conditions

The missing research: why women's gut health has been overlooked in favor of vaginal microbiome studies

Fembiome: designing microbiome targeted supplements with women, for women

The science behind their perimenopause supplement and why clinical trials matter

Why women need to be included in clinical research across all life stages

The EU endometriosis grant: defining baseline microbiome health before surgery or hormone therapy

One symptom women should never ignore: chronic fatigue

The question every woman should ask her doctor: could my diet be part of the problem?

Why young women and men need to be educated about PCOS and endometriosis in schools

How to get involved in women's health research and why your voice matters

The bottom line? Women's health is not just about fertility. It's about hormones, metabolism, pain, mood, and the gut microbiome that ties it all together. If you've been told your symptoms are normal or that you just need to push through, it's time to ask better questions. Mind your microbiome, prioritize fiber, support your liver, and don't ignore chronic fatigue. You deserve answers, not dismissal. The science is here. Now it's time to use it.

Are seed oils really toxic? Is snacking ruining your health? Should you obsess over every ingredient label? Dr. Sarah Berry, Professor of Nutritional Sciences at King's College London and Chief Scientist at Zoe, joins us to cut through the noise and tackle the biggest myths in nutrition science.

With over 25 years of experience and more than 35 human clinical trials under her belt, Sarah reveals why single ingredient demonization is misleading, how food structure matters more than you think, and why the back of pack label only tells half the story. From whole almonds versus ground almonds to the hidden impact of food texture on how much you eat, this episode will change the way you think about food forever.

Topics covered:

Dr. Sarah Berry's background in nutrition science and her work at Zoe

The seed oil controversy: why the evidence doesn't support the fear

Why demonizing single ingredients is scientifically misleading

Beyond the label: understanding the food matrix and why it matters

The power of food structure: whole versus ground almonds and metabolic impact

How food texture affects eating speed and calorie consumption

The gut microbiome: your personal food processor and how it shapes health

Menopause and microbiome: the soy isoflavone example and equal producers

Can we modulate our gut microbiome through diet and probiotics?

The gut brain connection and why you feel better fast with dietary changes

Snacking: the misunderstood quarter of our daily calories

Late night eating and circadian rhythm disruption

Time restricted eating: why a 10 hour window works

Why consistency in eating patterns matters more than perfection

Personal nutrition myths and habits: what even experts get wrong

The habit of late night grazing and how to break it

Starting your health journey: breakfast changes and small sustainable steps

The bottom line? Food is far more complex than a list of ingredients. The structure, texture, timing, and consistency of what you eat matter just as much as the nutrients themselves. Stop demonizing single foods, stop chasing perfection, and start focusing on what you can add in rather than what you're doing wrong. Your gut microbiome is adaptable, your body responds quickly to positive changes, and small shifts like swapping your snacks or slowing down your eating speed can have massive impacts. Don't sweat the small stuff. Focus on progress, not perfection.

Why has women's health been historically overlooked? What is FemTech, and how is it changing medicine for half the population? And what opportunities exist right now to solve problems that have been ignored for decades?

Dr. Tanya Mulcahy, biochemist and expert in health innovation, joins Barry Skillington to unpack the science, the gaps, and the massive opportunity in women's health technology. From endometriosis affecting 1 in 9 women to continuous hormone monitoring, from the mammogram redesign to the investment challenges holding back female founders, this episode reveals why FemTech isn't just about pink products. It's about real medical solutions backed by clinical evidence.

For too long, women were excluded from clinical trials. For too long, their symptoms were dismissed, their conditions misdiagnosed, and their health treated as an afterthought. But the landscape is shifting. Women are founding companies, investors are paying attention, and technology is finally catching up to the reality that women's bodies are not just smaller versions of men's. From puberty to pregnancy to perimenopause and beyond, women experience unique health challenges that demand unique solutions. The question is: who's going to build them?

Topics covered:

Dr. Tanya Mulcahy's background in health innovation and supporting FemTech development

Why women were excluded from clinical trials and how that created a research gap

What FemTech is: technology designed for women's health and wellbeing

The women's health journey: puberty, periods, fertility, pregnancy, postpartum, perimenopause, menopause, and aging

Endometriosis: what it is, why it takes 9 years to diagnose, and why 1 in 9 women suffer from it

Polycystic ovarian syndrome, fertility issues, and pregnancy complications

Postpartum depression, breastfeeding challenges, and mental health after childbirth

Perimenopause and menopause: hormone decline, symptom management, and the role of HRT

Why women live longer but in poorer health: bone density, muscle loss, and heart disease

The Health Innovation Hub: how it supports FemTech founders and innovators

The importance of clinical evidence: why your product must work, not just sound good

Investment challenges: why FemTech startups struggle to get funding and what's changing

The future of FemTech: continuous hormone monitoring from puberty through menopause

Preventative medicine and lifestyle technology: early diagnostics and real time feedback

Continuous glucose monitoring and how real time data changes behavior

Pink washing versus real medical solutions: fluffy pillows don't count

Rethinking medical devices: the mammogram example and why comfort matters

New mammogram technologies designed by women for women

Taking the leap: turning your idea into reality without leaving your job

Support systems in Ireland: Enterprise Ireland, universities, and clinical research organizations

Overcoming fear of failure and building confidence to innovate

The opportunity for the next generation: digital solutions and medical devices

Working with clinicians: why doctors want to help solve problems they can't fix alone

Final encouragement: if you think there must be a better way, you're already on the path to innovation

The bottom line? Women's health has been overlooked, underfunded, and under researched for far too long. But the opportunity to change that is right now. FemTech isn't about pink products or fluffy marketing. It's about real medical solutions backed by clinical evidence that address conditions affecting women only, women differently, or women disproportionately. From continuous hormone monitoring to better diagnostic tools to lifestyle interventions that prevent disease before it starts, the technology is coming. But it needs innovators. It needs women and men who see a problem and say there must be a better way. You don't need to be a doctor, an engineer, or a business expert. You just need a good idea, the willingness to validate it, and the courage to take the leap. Support systems exist. Funding is available. Clinicians want to help. The future of women's health is being built right now. Be part of it.

What if the health advice you're following isn't backed by science? What if the cure you saw on TikTok is actually delaying treatment for something serious? And how do you know which health claims to trust when everyone online seems to have a different answer?

Dr. Nontokozo Yusuff, a GP with over 15 years of experience across South Africa and Ireland, joins Barry Skillington to cut through the noise and tackle medical misinformation head on. From old wives' tales to social media algorithms, from Dr. Google to clinical evidence, this episode reveals how to spot misleading health claims, when to seek medical attention, and why trusting medicine doesn't mean you're giving up control.

Medical misinformation sits on a spectrum. On one end, harmless myths like swallowing gum will glue your insides together. On the other, dangerous delays in seeking treatment for conditions that are treatable and effective. The problem isn't just deliberate lies. It's outdated information, influencers with good intentions but no evidence, and symptom checkers that lack the personalized context only a healthcare professional can provide.

Topics covered:

Dr. Nontokozo Yusuff's background in medicine and clinical research
What medical misinformation actually is and why it matters
Old wives' tales versus clinical evidence: where do anecdotes fit?
The role of clinical trials in validating health claims
Why randomized controlled trials minimize bias and produce reliable results
Red flags: cure alls, instant results, and vague language like "boosts" or "supports"
How to spot credible products: look for references to clinical studies
The problem with Dr. Google and AI diagnosis: missing the personalized context
Why symptom checkers list possibilities but can't replace clinical judgment
When to seek medical attention: persistent symptoms, unusual severity, and daily impact
The importance of routine checks: blood pressure, glucose, cholesterol, and self exams
Overcoming fear of lifelong medication and why it's often necessary
Why diet alone won't control dangerously high blood pressure or cholesterol
Trusting medicine: safety standards, drug development, and post market surveillance
Why pharmaceutical companies follow stringent guidelines before drugs hit the market
The phases of clinical trials and how long it takes to validate a medication
Recalls are safety measures, not failures: catching issues before they escalate
Social media algorithms and how they feed you more of what you've already seen
Why influencers and anecdotal evidence have power but lack scientific backing
Navigating conflicting health advice: coffee is good, coffee is bad, what do you do?
Medicine evolves: guidelines change as new evidence emerges
Natural doesn't mean safe: herbs and supplements can have side effects too
Key takeaways: pause before making health decisions, check your sources, and trust clinical evidence

The bottom line? Your health is too important to leave to viral trends, influencers, or outdated advice. Stop relying on Dr. Google for diagnoses. Stop avoiding medication out of fear. Stop believing that one miracle cure will solve everything. Clinical evidence exists for a reason. Drugs go through years of rigorous testing before they reach you. Doctors aren't hiding cures. They're following the best available science to keep you safe. Check your sources. Look for clinical trials. Be curious, not skeptical. And remember: tools like AI and social media are just that, tools. They don't replace professional judgment. Trust medicine. Trust your doctor. And take control by making informed decisions based on real evidence, not sensational headlines.

Why do diets fail? Why are you always hungry? And what if the secret to managing your weight isn't about eating less, but eating better?

In this episode of Straight Talking Science, Barry Skillington sits down with Dr. Harriët Schellekens, senior lecturer in the Department of Anatomy and Neuroscience at UCC, funded investigator for APC Microbiome Ireland and Food for Health Ireland, and leading expert on appetite hormones and the gut brain axis. Harriët unpacks the science behind hunger, cravings, and why your body fights back when you crash diet.

From GLP-1 drugs like Ozempic to ghrelin, the hunger hormone, to the hidden role of your gut microbiome in driving food choices, this conversation reveals why appetite isn't just about willpower. It's biology. Your gut hormones, your stress levels, your sleep, and the trillions of microbes living inside you are all constantly communicating with your brain, influencing what you eat, how much you eat, and whether you can stop.

Topics covered:

Dr. Harriët Schellekens' research on appetite hormones and the gut brain axis
What GLP-1 drugs are, how they work, and who should actually be taking them
Why obesity is a disease, not a lifestyle problem
The biology of appetite: hormones versus willpower
Ghrelin: the hunger hormone that drives food intake and why it matters
How ghrelin dysregulation contributes to obesity and emotional eating
The problem with ultra processed foods and the pre digestive versus post digestive mismatch
Why high fat high sugar combinations trick your brain and drive overeating
Sugar substitutes: the good, the bad, and the science behind natural sweeteners like allulose
The gut microbiome's role in weight, appetite, and food cravings
How your microbes can harvest more calories from food and influence obesity risk
Microbiome diversity across life stages: from infancy to aging
How gut bacteria signal to your brain to modulate food motivation and preferences
Stress, cortisol, and emotional eating: the hormonal connection
Why crash diets fail: the hormone perspective and what happens when you restrict calories
Practical food strategies: fixing the mismatch between taste and nutrition
Early life programming: how childhood diet shapes eating behavior and obesity risk later in life
Probiotics, prebiotics, and targeted microbial interventions for appetite regulation
Parenting and food: teaching kids healthy habits without guilt or fear
Key takeaways: eat better, not less, and why lifestyle changes beat quick fixes

The bottom line? Diets don't work because they fight your biology. When you restrict calories, your body responds by increasing ghrelin, raising cortisol, and making you crave the exact foods you're trying to avoid. Ultra processed foods create a mismatch between what your mouth tastes and what your gut actually receives, driving overeating and dysregulating your appetite hormones. Your gut microbiome plays a massive role in how much energy you extract from food, what foods you crave, and how your body responds to stress. The solution isn't eating less. It's eating better. Whole foods, fiber, protein, and slow release carbohydrates that match the promise of calories with actual nutritional delivery. Feed your microbes, balance your hormones, prioritize sleep, manage stress, and stop crash dieting. Your body is designed to work with you, not against you. Give it the right signals, and it will respond.
