My Adrenal Life

Why can brain fog, forgetfulness and difficulty concentrating persist when cortisol replacement is considered adequate? This My Adrenal Life episode explores the gap between treating adrenal insufficiency and understanding how someone functions throughout an ordinary day.

Based on Karen Harbison’s “When Replacement Is Adequate but the Brain Still Struggles — Part 4,” the final installment of The Brain on Cortisol: More Than a Stress Hormone, two AI hosts discuss how attention, memory, sleep and cortisol exposure can overlap—and why persistent symptoms deserve a fuller conversation with the healthcare team.

Topics include:

• What adequate replacement can tell us, and what it cannot establish about brain function

• Attention, encoding and retrieval: why a memory complaint may involve several processes

• Circadian and ultradian cortisol patterns versus conventional oral replacement

• Sleep, fatigue and quality of life in Addison’s disease

• Individual differences in medication response and other contributors to cognitive symptoms

• Subjective brain fog, objective testing and everyday demands

• A symptom diary and practical questions to bring to a clinician

Differences in hormone patterns do not by themselves establish the cause of someone’s symptoms. Observational sleep findings do not prove that replacement medication caused those difficulties, and research in healthy adults is not an adrenal-insufficiency treatment trial. Evidence that newer replacement approaches consistently restore cognition remains limited.

Why can adrenal insufficiency still feel difficult to manage when you take replacement medication as prescribed? This episode explores cortisol timing, the distinction between replacing a hormone and recreating its natural secretion, and what current research can—and cannot—tell us about persistent symptoms.

AI hosts Lily and James discuss Karen Harbison’s article, “Part 3 — Replacing Cortisol Is Not the Same as Recreating Its Rhythm,” including:

• The brain’s circadian clock and cortisol’s rise before waking

• Ultradian pulses and why fluctuating hormone signals can affect cellular responses

• Laboratory and mouse findings, and why they cannot diagnose an individual’s brain fog

• Modified-release hydrocortisone research, including the 58-participant CHAMPAIN crossover study

• The 33-patient Addison’s disease infusion-pump trial, biochemical and vitality findings, and its lack of observed sleep benefit

• Questions about symptoms, sleep, treatment goals and other possible causes to discuss with your healthcare team

The evidence has limits: cellular mechanisms are not proof of clinical benefit, CHAMPAIN treatment periods lasted four weeks and fatigue results were mixed, and no delivery method discussed fully recreates natural ultradian secretion. A perceived energy dip alone cannot establish that replacement needs changing. This discussion offers no personalized dosing or medication-switching advice.

Why can a familiar name disappear or an appointment time slip your mind? In this My Adrenal Life episode, AI hosts Lily and James explore cortisol, memory and brain fog through Karen Harbison’s article, “Part 2 — Cortisol, Memory, and the Science of Forgetting.”

The conversation follows three stages of remembering—encoding, consolidation and retrieval—and explains the roles of attention, the hippocampus, prefrontal cortex and emotional salience. It also looks at how cortisol interacts with mineralocorticoid and glucocorticoid receptors, why a vivid memory is not necessarily an accurate one, and why sleep matters for learning.

Topics include:

• Everyday examples of attention, memory formation and recall

• Cortisol timing, stress and sleep research

• Healthy-volunteer experiments versus evidence in adrenal insufficiency

• A secondary adrenal insufficiency crossover trial and the limits of interpreting its cognitive results

• Learning supports: repeating information, retrieval practice, spaced learning, calendars and reminders

• Bringing new or worsening memory concerns to your healthcare team

Memory difficulties can have multiple causes. Laboratory findings do not identify the cause of an individual’s symptoms or establish a replacement schedule. This episode is an educational discussion, not a recommendation to change medication or dosing.

Why can brain fog, memory difficulties, or mental fatigue persist when you are already taking cortisol replacement for adrenal insufficiency? Understanding the brain’s role in cortisol regulation helps explain why the answer involves more than the adrenal glands—and why symptoms deserve a broader medical evaluation.

In Part 1 of “The Brain on Cortisol: More Than a Stress Hormone,” this My Adrenal Life conversation explores Karen Harbison’s article, “The Brain That Controls Cortisol.” Finn and Mia unpack the hypothalamic-pituitary-adrenal (HPA) axis and the two-way communication between cortisol and the brain.

In this episode:

• How CRH, ACTH, and cortisol work together through negative feedback

• How primary, secondary, and tertiary adrenal insufficiency interrupt different parts of that signaling system

• Why essential glucocorticoid replacement does not necessarily restore natural cortisol production

• Mineralocorticoid and glucocorticoid receptors in the brain, and why concentration and timing matter

• Circadian rhythms and ultradian pulses, and the limits of conventional oral replacement

• What research suggests about cognitive symptoms—and why mixed study findings do not support one explanation or treatment for everyone

Cognitive difficulties do not automatically mean your cortisol replacement is inadequate. Sleep and other medical conditions can also contribute. Discuss persistent symptoms with your healthcare team; this episode does not recommend changing medication or doses.

Recovery after glucocorticoid-induced HPA suppression varies among individuals. Neither recovery nor improvement in cognition from a particular replacement approach is guaranteed.

What happens when you need emergency care for adrenal insufficiency and the hospital has no available bed? Emergency department boarding can complicate timely treatment, medication continuity, and communication—concerns that matter for people with Addison’s disease, secondary adrenal insufficiency, and steroid-induced adrenal insufficiency.

In this My Adrenal Life episode, Lily and James explore Christin Disler’s article, “When the Emergency Room Has No Room: What Hospital Overcrowding Means for People With Adrenal Insufficiency.” They connect the physiology of cortisol deficiency with research on hospital boarding and practical ways patients and advocates can communicate urgent needs.

In this episode:

• How boarding after a decision to admit differs from the initial triage wait

• Why cortisol replacement and changes in illness severity need ongoing attention during handoffs

• What observational studies suggest about medication errors and treatment delays—and what they cannot establish about adrenal-specific outcomes

• Differences between primary, secondary, and tertiary adrenal insufficiency

• Prescribed emergency injection kits, individualized rescue plans, and the role of a patient advocate

• What EMTALA requires and why it does not guarantee an immediate inpatient bed or a particular triage priority

Suspected adrenal crisis requires immediate emergency care. Follow your prescribed rescue plan and injection training, call emergency services, and do not delay care because a hospital is crowded. Discuss your own emergency plan and medication needs with your healthcare team.

The boarding studies discussed involve general patient populations. They do not prove that boarding causes a particular rate of adrenal crisis or establish outcomes specifically for people with adrenal insufficiency.

Living with adrenal insufficiency can bring emotional exhaustion, grief, and uncertainty alongside the physical symptoms. Can gratitude, self-compassion, and realistic hope help you find meaning in a life you didn’t choose—without pretending everything is okay?

In this My Adrenal Life episode, James and Oliver explore Christin Disler’s article, “Finding Light in a Life You Didn’t Choose,” and the emotional side of living with adrenal insufficiency, including Addison’s disease and secondary adrenal insufficiency.

The conversation connects research on gratitude and repetitive negative thinking with everyday experiences of chronic illness: canceling plans, missing your former independence, feeling guilty for needing rest, and wondering whether your diagnosis has become your whole identity.

In this episode:

• Emotional exhaustion and the grief of a life changed by chronic illness

• Cognitive reframing: acknowledging difficult facts without turning them into judgments about your worth

• What gratitude research suggests about emotional well-being—and why the average benefits are modest

• Why gratitude does not restore cortisol production or replace glucocorticoids and prescribed emergency plans

• How gratitude and grief can exist at the same time

• Savoring small moments, practicing self-compassion, and trying a flexible “both can be true” reflection

• Recognizing when professional mental health support or medical attention is needed

The gratitude trial discussed was not specific to people with adrenal insufficiency and did not establish effects on cortisol production, medication requirements, or adrenal crisis prevention. These practices support emotional coping; they are not a replacement for appropriate medical care.

You don’t have to feel positive every day to live a meaningful life. Your diagnosis may shape your circumstances, but it does not define your full value.

In this episode of My Adrenal Life, we explore the fourth and final article in our educational series, What Happens to Your Steroid Medication After You Swallow It?

Glucocorticoid replacement is essential for people living with adrenal insufficiency, but conventional oral hydrocortisone cannot fully reproduce the body’s natural cortisol rhythms. This raises an important question: Could changing when and how cortisol is delivered improve treatment outcomes?

We examine the science behind circadian and ultradian cortisol rhythms, why conventional hydrocortisone creates peaks and valleys in blood concentrations, and how researchers are developing alternative delivery methods.

A major focus is the difference between two modified-release hydrocortisone formulations: Plenadren, designed to provide daytime cortisol exposure, and Chronocort/Efmody, designed to more closely reproduce the natural rise in cortisol before waking.

We also discuss the January 2026 CHAMPAIN clinical trial, which compared these formulations in 58 patients with primary adrenal insufficiency. Chronocort produced substantially higher early-morning cortisol concentrations, and several patient-reported fatigue and quality-of-life measures favored Chronocort. However, not every outcome improved significantly, highlighting the need for further research.

The conversation also explores continuous subcutaneous hydrocortisone infusion, commonly called cortisol pump therapy. Clinical studies suggest pumps can more closely reproduce natural cortisol patterns, although research findings on improvements in symptoms and quality of life have been mixed.

We examine emerging technologies, including wearable cortisol sensors and the possibility of future systems that could combine continuous cortisol monitoring with automated medication delivery. These technologies are promising research directions but are not yet established routine treatment options.

Throughout the discussion, we consider why a more physiological cortisol curve does not automatically guarantee better health, why patient experiences vary, and why researchers must look beyond laboratory measurements to outcomes such as fatigue, sleep, adrenal crisis frequency, long-term health, and quality of life.

Although much of the existing research focuses on primary adrenal insufficiency, we also discuss the importance of expanding studies to include secondary, tertiary, and glucocorticoid-induced adrenal insufficiency.

The central takeaway: The future of glucocorticoid replacement may involve understanding not only how much cortisol a person receives, but when and how that cortisol becomes available—and whether those differences meaningfully improve everyday life.

Why Your Cortisol Dose Isn't Working — Part 3: Why Your Liver Rewrites Your Prescription

Why can two people take the exact same dose of hydrocortisone and experience completely different results? What if the difference isn't how much medication they take, but how their bodies process it?

In Part 3 of our My Adrenal Life Podcast series, What Happens to Your Steroid Medication After You Swallow It?, we explore the fascinating science of liver metabolism, medication clearance, and why the dose on your prescription bottle doesn't tell the whole story.

In Parts 1 and 2, we examined how hydrocortisone enters the bloodstream. Now we follow that medication into the liver and tissues, where enzymes determine how steroid hormones are activated, deactivated, processed, and eliminated.

We begin by exploring the difference between cortisol production and cortisol metabolism. Even when someone cannot produce enough cortisol naturally, their body continues processing the replacement medication they take.

We discuss two important enzymes, 11β-HSD1 and 11β-HSD2, which regulate the conversion between active cortisol and inactive cortisone. These processes help determine cortisol activity within individual tissues, meaning circulating hormone concentrations don't always tell the complete story.

We also examine CYP3A4, a liver enzyme involved in metabolizing many medications, including certain glucocorticoids.

In this episode, we explore:

• Fast versus slow metabolism: Why some people may process glucocorticoids differently and why symptoms alone cannot establish rapid clearance.

• Medication interactions: How drugs such as rifampin and certain seizure medications can accelerate steroid metabolism, while other medications can slow clearance and increase glucocorticoid exposure.

• Supplements matter too: Why products such as St. John's wort can interact with medication-processing enzymes.

• The difference between steroids: Why hydrocortisone, prednisone, prednisolone, and dexamethasone have different activation pathways, durations, and metabolic characteristics.

• Liver disease and cortisol: How impaired liver function and changes in cortisol-binding proteins can complicate medication exposure and laboratory interpretation.

• Genetics and individual differences: Why someone's metabolic response involves more than a single gene.

• Emerging research: How blood testing and urinary steroid metabolomics may help researchers better understand individual hormone-processing pathways.

We also discuss a published case involving a patient with primary adrenal insufficiency whose previously stable hydrocortisone replacement became inadequate after starting rifampin.

The case illustrates an important reality: a medication interaction can change glucocorticoid exposure even when someone hasn't missed a single dose.

On the opposite side, medications that inhibit steroid metabolism can increase exposure to certain glucocorticoids, potentially contributing to excessive steroid effects and suppression of the body's natural cortisol production.

These interactions make it especially important for people with primary, secondary, tertiary, or steroid-induced adrenal insufficiency to review new medications and supplements with their healthcare team.

Throughout the conversation, we emphasize that feeling like hydrocortisone wears off quickly doesn't automatically mean you're a fast metabolizer. Absorption, tissue sensitivity, other medications, and individual physiology may all contribute.

The takeaway? Your prescription tells you how much medication you take. Your body determines how that medication is processed. Understanding both matters.

Why Your Cortisol Dose Isn't Working — Part 2: Is Your Body Actually Absorbing Your Hydrocortisone?

You take your hydrocortisone, wait for it to start working, and sometimes nothing happens. Or the relief comes much later than expected. Why?

For people living with adrenal insufficiency, knowing that medication was swallowed isn't quite the same as knowing how quickly—or how much of it—reached the bloodstream.

In Part 2 of our My Adrenal Life podcast series, What Happens to Your Steroid Medication After You Swallow It?, we explore the science of hydrocortisone absorption and why digestive health can influence how replacement medication behaves.

Research suggests that oral hydrocortisone is generally absorbed very efficiently, with one controlled study reporting approximately 96% bioavailability. But that average doesn't guarantee identical absorption or timing for every person.

We explain the journey of a hydrocortisone tablet through the digestive system, from breaking apart and dissolving to passing through the intestinal lining and entering circulation.

In this episode, we explore:

• Delayed absorption versus reduced absorption: Why medication arriving late isn't necessarily the same as medication being lost.

• Food and medication timing: How meals may change the timing and peak of hydrocortisone absorption, depending on the formulation.

• Gastroparesis: Why delayed stomach emptying raises important questions about medication delivery, even though direct hydrocortisone research remains limited.

• Crohn's disease and celiac disease: How intestinal inflammation, damaged intestinal lining, and disease location may affect absorption—and where the evidence is still incomplete.

• Vomiting and diarrhea: Why gastrointestinal illness creates special concerns for people who depend on oral glucocorticoid replacement.

• Bariatric surgery: What a small study found about hydrocortisone exposure after gastric bypass and sleeve gastrectomy, including some surprising results.

• Understanding cortisol curves: What researchers mean by Tmax (time to peak), Cmax (peak concentration), and AUC (overall medication exposure).

We also discuss an important distinction: feeling unwell does not automatically mean your medication isn't being absorbed.

Sometimes the problem may involve delayed absorption. Sometimes illness increases the body's cortisol requirements. Other possibilities include medication clearance, dehydration, or symptoms caused by another medical condition.

Understanding these differences can help patients describe their experiences more clearly and have more informed conversations with their endocrinologists.

We also address the serious safety implications of persistent vomiting or severe diarrhea. When oral glucocorticoids cannot be reliably retained or absorbed, established emergency protocols and prompt medical care become essential.

Throughout the conversation, we examine what published research supports, what remains uncertain, and why conditions such as gastroparesis, active celiac disease, and long-term changes following bariatric surgery deserve further study.

The central takeaway? Hydrocortisone is generally well absorbed, but how quickly it reaches the bloodstream—and how consistently that happens—can matter. Digestive symptoms alone cannot tell us exactly what is happening to a dose.

This discussion is relevant to people with primary, secondary, tertiary, and glucocorticoid-induced adrenal insufficiency who depend on oral replacement medication.

Coming in Part 3: Once hydrocortisone reaches the bloodstream, what happens next? We'll explore liver metabolism, medication clearance, interactions with other drugs, and why some people may process glucocorticoids faster or slower than others.

Why Your Cortisol Dose Isn't Working — Part 1: What Happens After You Swallow Hydrocortisone?

Why can two people take the exact same dose of hydrocortisone and have completely different experiences?

One person feels relatively stable throughout the morning. Another experiences a brief improvement followed by overwhelming fatigue, brain fog, or a sudden crash.

Both may be following their prescribed treatment plan. So why does the same medication behave so differently?

In this episode of the My Adrenal Life Podcast, we explore the science behind how the body processes hydrocortisone and why the dose printed on your prescription bottle doesn't necessarily tell the whole story about your body's cortisol exposure.

Research discussed in this episode found that cortisol exposure can vary more than tenfold between individuals, even when researchers account for body weight. Another study demonstrated substantial differences in cortisol concentrations following intravenous hydrocortisone administration, showing that the digestive system is only one part of the equation.

We break down the four stages of pharmacokinetics, known as ADME: Absorption, Distribution, Metabolism, and Excretion.

You'll discover why the speed of absorption, cortisol-binding proteins, liver metabolism, medication clearance, and tissue-level hormone activity can all influence how hydrocortisone behaves.

We also explore some of the questions frequently raised in the adrenal insufficiency community:

• Why does hydrocortisone seem to wear off sooner for some people?

• Does crashing between doses necessarily mean you're a fast metabolizer?

• What's the difference between total cortisol and free cortisol?

• How can estrogen therapy and cortisol-binding globulin influence cortisol measurements?

• Why doesn't adjusting medication solely by body weight eliminate individual differences?

• How do natural cortisol rhythms differ from the peaks and declines produced by oral medication?

• Why can't one cortisol blood test or symptom pattern tell the entire story?

This conversation applies to people living with primary adrenal insufficiency (Addison's disease), secondary adrenal insufficiency, tertiary adrenal insufficiency, and glucocorticoid-induced adrenal insufficiency.

We also discuss the difference between pharmacokinetics—what your body does to medication—and pharmacodynamics—how that medication affects your tissues.

Perhaps one of the most important takeaways is that feeling worse between doses does not automatically establish that you need more medication. Absorption, timing, clearance, other health conditions, and individual responses may all contribute. Understanding those differences can help patients have more informed conversations with their endocrinologists without risking unnecessary overreplacement.

We look at where the research stands today, why scientists still cannot identify one ideal cortisol exposure pattern for every patient, and how newer hydrocortisone delivery approaches may help address some limitations of conventional replacement therapy.

The central message? Two people taking 20 mg of hydrocortisone may experience very different patterns of cortisol exposure. Comparing prescription doses alone doesn't tell us how their bodies are responding.

This episode is about understanding the science behind those differences, recognizing what research has established, and identifying the questions that still need answers.

Coming in Part 2: We take a closer look at hydrocortisone absorption and what happens when gastrointestinal conditions such as celiac disease, Crohn's disease, or changes in stomach emptying interfere with the journey from tablet to bloodstream.
