A short preview of this episode.

Histamine intolerance and MCAS have taken over the internet, and they describe very different problems. Colin Renaud and Dr. Sasha Rose open with a patient who flushes after a small glass of wine and after aged cheese, gets random hives and headaches, takes a daily antihistamine, and has eliminated her way down to 15 safe foods. She is pretty sure it is MCAS.

Dr. Rose's answer is the line the episode turns on: it is not the food that is the problem. If she leaves with 20 safe foods instead of 15 and the same antihistamine, nobody has done their job.

They draw the line between the two conditions (histamine intolerance is a capacity problem, MCAS is a mast cell behavior problem), walk through what the MCAS criteria actually require, why tryptase can mislead, what an allergist's workup rules out first, where the "17% of people have MCAS" number came from and why the two of them disagree about it, what to do when the low-histamine diet stops working, and where testing really begins. Then a live Q&A on medication fillers, dermatographism, hormones and histamine, and updated MCAS testing.

Colin closes with one of his most complex cases: a patient in her twenties on a continuous IV antihistamine infusion, living on chicken and rice cakes for close to three years, and the workup that gave her a way back.

Fibromyalgia is one of the most dismissed conditions in medicine. Colin Renaud and Dr. Sasha Rose open with a patient: a woman in her fifties, five years of widespread pain, unrefreshing sleep, multiple specialists, every test normal, and more than one doctor suggesting stress or anxiety.

Dr. Rose's point is the one the episode turns on. Normal results are good news. They mean nothing dangerous was found. They do not mean the pain is not real, and there is a huge gap between those two things.

They cover what fibromyalgia actually is and why it is not a diagnosis of exclusion, what central sensitization means, the six-and-a-half-year average road to a diagnosis, everything that has to be ruled out first (thyroid, iron, vitamin D, B12, inflammatory arthritis, sleep apnea, celiac, medication side effects), what the internet gets right and wrong, why aggressive online protocols backfire on these patients, and what functional medicine changes about the plan. Then a live Q&A on genetics, acupuncture, triggers and why symptoms can feel worse over time.

Her takeaway: your pain is real. It has a mechanism. There is a real difference between a condition nobody can explain and a condition nobody has properly looked for.

Hashimoto's is an autoimmune condition first and a thyroid condition second. As Gabriel Rocha, PA-C puts it, it is your own body's immune system attacking your body, which means two things are happening at once: the immune process itself, and the effect it has on thyroid production. A TSH alone speaks to the second and almost nothing to the first.

He opens with a patient, a woman in her mid-fifties who had lived with Hashimoto's for years and had been through the pattern where some labs read relatively normal, others shift, and she still did not feel well.

He is careful with the numbers. Antibody levels fluctuate, a falling antibody number does not mean Hashimoto's is cured, and he does not use it alone to judge whether someone is better. What mattered was the person. Over roughly six months her bloating resolved, her sleep became excellent, and after an adjustment to her thyroid hormone she described feeling amazing. Not one magical number, not one supplement. They stopped treating her like a TSH result.

Bloated every day, reacting to food, exhausted after meals, and told it is IBS. Dr. Sasha Rose and Colin Renaud, PA-C explain what is actually being described by that label, and why it is a starting point rather than an answer.

They open with a patient. A man in his thirties, a year of feeling worse after meals, no obvious triggers, nothing he tried working, convinced from social media that he had a parasite. They come back to him later.

The line that anchors the hour: bloating is not a diagnosis, it is a symptom. Dr. Rose, who has specialised in gut health for over twenty years, walks through what leaky gut refers to, what SIBO is and how it is genuinely diagnosed, why breath test timing matters, what food triggers look like when you identify them properly, and what gut function has to do with iron and B12.

The case that stays with you comes near the end. A patient who had seen countless gastroenterology providers was down to chicken and rice cakes, only that, for two and a half years. Her methane was too high for the lab to give a number. It took about a year to bring it below threshold.

Cold plunges, red light panels, IV drips, biological age testing, glucose monitors, supplement stacks, green powders, longevity memberships with a twenty dollar smoothie at the bar. Wellness became a status symbol, and patients bring all of it into the room with the same question: is it worth it?

Dr. Sasha Rose and Colin Renaud, PA-C go through what they get asked about most and what actually sits behind each one. They are also direct about their own position. Functional medicine is not covered by insurance, they say so out loud, and they are not arguing for a model only some people can afford.

The answer arrives near the end. Asked what moves health at the lowest cost, Colin lists walking, strength training, protein, fibre, hydration, consistent sleep, morning light, balanced blood sugar, stress regulation, fewer ultra processed foods and awareness around alcohol. Then the line that sums up the hour: those foundations might not be the lowest, but the sexiest.

Every particle that carries cholesterol into an artery wall has exactly one ApoB protein on its surface. A standard cholesterol panel measures how much cholesterol you are carrying, not how many particles are carrying it, and those two numbers can disagree.

Colin Renaud, PA-C explains what ApoB is, how someone ends up with a normal LDL and an elevated ApoB, and why insulin resistance and triglycerides sit underneath that pattern more often than people expect. He covers what particle count tells you that total cholesterol cannot, genetically influenced risk markers, CRP and inflammation, and the role cholesterol plays in making hormones.

He is careful about statins and says plainly that he is not anti-medicine. Statins calm inflammation and standards of care exist for good reasons. His argument is that one number on one panel is a thin basis for a decision that shapes the next thirty years, and that there is more worth looking at.

Cognitive peptides have become one of the loudest conversations in the nootropic and longevity space, and one of the least understood. Dr. Sasha Rose and Colin Renaud, PA-C talk through Selank and Semax: what they are, what the research has actually evaluated, and where the honest limits sit.

Colin is careful with the evidence. Much of what exists is laboratory and animal work. Some human trials were conducted in Russia. Semax only recently entered the FDA compounding conversation when the Pharmacy Compounding Advisory Committee discussed Semax-related substances. Animal data on BDNF is a reason to study something, not proof that it works in people.

Dr. Rose keeps returning to the foundation underneath any of it. Sleep, nutrients, blood sugar, inflammation and stress physiology. B12, folate, iron, vitamin D and thiamine, and what they have to do with fatigue and cognition. Both are direct that none of this replaces psychiatric care, and that someone already on psychiatric medication needs their prescribing provider in the conversation.
