Extend Podcast with Darshan Shah, MD

When labs look normal, it is easy to assume the body is fine or that the biggest risks have been ruled out. Dr. John Kim's story challenges that belief. At 33, after a normal lipid panel and without the classic heart attack picture, he ended up with an 85% blockage in his LAD. That experience forced him to ask what standard markers were missing.
The answer led him into the deeper cellular stressors that can keep the body in defense mode: mold, mycotoxins, chronic infections, biofilms, heavy metals, emotional trauma, gut dysfunction, damaged cell membranes, and mitochondrial stress. In this episode of Extend, I sit down with Dr. Kim to talk about how these stressors can push the mitochondria away from energy production and into the cell danger response, where the body is still trying to protect itself but starts paying the price through brain fog, fatigue, inflammation, hormone disruption, gut issues, and hypersensitivity.
Dr. John Kim is a functional pharmacist whose work focuses on mold toxicity, mitochondrial health, lipid membrane medicine, chronic infections, gut health, and structured detox support. This episode gives listeners a new framework for symptoms that do not make sense on standard labs, from brain fog and fatigue to chronic inflammation, hormone disruption, gut issues, and hypersensitivity, while showing why recovery has to happen in the right sequence before the body can fully rebuild.
What's Discussed:
(03:39) The heart attack at 33 that doctors almost missed.
(05:01) Why a normal lipid panel did not explain what was happening underneath.
(09:52) Why heart disease goes beyond cholesterol.
(12:26) How biofilms can hide chronic infections from the immune system.
(17:43) What the cell danger response does to mitochondria and energy production.
(23:41) Why mold and mycotoxins can affect the brain, gut, immune system, and hormones.
(42:01) How the ENCORE method helps sequence recovery from mold and cellular stress.
Listen to this episode of Extend to understand why "normal" does not always mean resolved, how hidden stressors can keep your cells on defense, and why recovery may need to start with the environment, nervous system, gut, detox pathways, and cell membrane before deeper healing can happen.

Most people assume that once they leave a mold-exposed building, their body should recover. But I see this all the time in my clinic, the mold exposure ends, and the symptoms don't.
In this episode of Extend, I sit down with Dr. Scott McMahon, medical director at MoldCo, to ask why removing the source doesn't always mean removing the illness. We get into a switch inside the immune system, one that determines whether the body can actually call off an inflammatory response once a threat is gone, and what happens when that switch stops working. Understanding it changes how a long list of unexplained, lingering symptoms starts to make sense.
Dr. Scott McMahon spent eighteen years as a pediatrician before a case involving a group of sick high school students redirected the entire focus of his career. He went on to study under Dr. Richie Shoemaker, the physician who first identified Chronic Inflammatory Response Syndrome (CIRS), and has spent years treating patients, publishing research on the condition's diagnostic criteria, and co-authoring a book on CIRS medicine. As medical director of MoldCo, he now works at the intersection of testing, treatment, and education for a condition that affects an estimated one in four people genetically, making him one of the most credible voices in the country on this topic.
What's Discussed:
(3:43) The high school case that revealed how multi-system illness can hide behind symptoms doctors are trained to treat separately.
(6:55) The difference between a mold allergy and a full immune system malfunction, and why they are not the same thing.
(10:29) What determines whether one person's body can shut off inflammation and another person can't.
(12:34) The ten lab markers that can actually confirm what's happening, and why most physicians have never ordered them.
(17:41) Why a popular at-home mold test might be telling you less than you think.
(21:41) How to check your own home for the signs most people walk right past.
(35:17) The real number of people walking around with this genetic predisposition, and why it's higher than almost anyone expects.
If symptoms have stuck around well after leaving a mold-exposed space, this conversation breaks down why, and what's actually keeping the body in that state long after the exposure ended.

Latest book: The Art and Science of CIRS Medicine

If you care about longevity, you have probably seen the same pattern over and over again. A new peptide, supplement, biological age test, off-label drug, or protocol starts gaining attention, and suddenly it sounds like the missing piece everyone should be using. The hard part is not wanting to be proactive. The hard part is knowing which claims have real evidence behind them, which ones are still early signals, and which ones may carry risks no one is measuring carefully enough.
In this episode, I sit down with Dr. Matt Kaeberlein to talk about how to think about longevity when the answer is rarely a simple yes or no. This conversation helps separate excitement from certainty, and shows why the real question is not only whether something might work, but whether the evidence, safety data, product quality, and risk-reward equation are strong enough to act on.
Dr. Matt Kaeberlein is a scientist in the biology of aging and one of the most respected voices bringing scientific discipline to the longevity conversation. He has been involved with the Interventions Testing Program, which rigorously tests aging interventions in mice, and is one of the leaders behind the Dog Aging Project, a large-scale study looking at aging, health, and longevity in companion dogs. His work sits at the intersection of curiosity and caution, which makes him the right person to talk about what is promising, what is overhyped, and what still needs better evidence.
What's Discussed:
(03:24) Why longevity marketing can move faster than the science.
(06:31) The risk-reward question most people skip before trying a new therapy.
(09:39) Why years of peptide use does not automatically mean safety is proven.
(20:00) The "research use only" peptide problem and why product quality matters.
(34:51) How the Interventions Testing Program separates stronger longevity signals from noise.
(38:39) Why rapamycin changed the field, and why some popular interventions failed to replicate.
(58:43) What the Dog Aging Project may teach us about rapamycin, healthspan, and human aging.
Listen to this episode of Extend to understand how to evaluate longevity claims with more clarity. You will hear what deserves excitement, what deserves caution, and what to ask before turning the next promising intervention into your personal health protocol.

A lot of women are taught to think about hormones only when something becomes impossible to ignore. Painful periods. Birth control decisions. Fertility anxiety. Postpartum changes. Perimenopause symptoms. Menopause. But what if those are not separate conversations? What if the body has been giving clues for years before the symptoms become loud enough to finally get attention?
In this episode, I sit down with Dr. Jila Senemar to look at women's hormone health through a much wider lens. We talk about why the ovary should not be seen only as a reproductive organ, why the hormone conversation needs to start before menopause, and what women may be missing when birth control, AMH, perimenopause, and hormone replacement are treated like separate decisions instead of one connected health story.
Dr. Jila Senemar is an OB-GYN and women's health physician who has spent years caring for women through cycle symptoms, contraception decisions, fertility questions, perimenopause, menopause, and hormone therapy. Her work brings together conventional women's health with a more proactive view of ovarian health, hormone longevity, gut health, bone health, and the full journey women move through over time.
What's Discussed:
(1:02:06) Why women's hormone health should be discussed before menopause.
(1:15:55) How AMH can become a women's health marker before fertility panic begins.
(1:20:50) Why birth control should not be the automatic answer for every cycle issue.
(1:22:07) What changed with lower-dose birth control options.
(1:24:55) How hormonal and non-hormonal IUDs fit into the conversation.
(1:27:36) Why perimenopause may need a different hormone strategy than standard birth control.
(1:31:34) Why hormone therapy should not ignore bone health, gut health, inflammation, and estrogen metabolism.
Listen to this episode of Extend to understand why women's hormones should not be treated like separate stages, and why the earlier clues from the ovary, cycle, gut, bones, and symptoms may matter more than most women are told.

When a couple is trying to get pregnant and it is not happening, the conversation can become very intense very quickly. Suddenly, you are hearing about IVF, egg freezing, AMH, sperm count, hormones, age, cost, and timing. But before the conversation jumps straight to the next procedure or the next number to panic over, there may be a deeper question worth asking: What is fertility trying to tell us about the health of the mother, the father, and the future child?
In this episode of Extend, I sit down with Dr. Labib Ghulmiyyah to talk about fertility and pregnancy through a much bigger lens. This conversation looks at infertility not as a failure, but as information. It helps explain why fertility struggles, sperm health, ovarian reserve, placental function, and pregnancy complications can all give clues about metabolic health, inflammation, cardiovascular health, hormones, sleep, stress, toxins, and long-term risk.
Dr. Labib Ghulmiyyah is an OB-GYN and residency director at Broward Health who brings together reproductive medicine, pregnancy care, longevity, and functional health. That combination matters because fertility is often treated like a separate category, when in reality, it is connected to the whole body. His approach helps couples think beyond "How do we get pregnant?" and start asking what their reproductive health may be revealing before, during, and after pregnancy.
What's Discussed:
(02:30) Why health optimization should happen before or alongside IVF.
(04:55) How long couples may need to optimize health before fertility treatment.
(07:17) Why the placenta may be one of the most overlooked biomarkers in pregnancy.
(10:40) Why pregnancy complications should be debriefed after delivery.
(18:40) Why the father's health matters far more than sperm count.
(26:15) How testosterone therapy can affect sperm production.
(41:29) Why low AMH does not automatically mean you cannot get pregnant.
Listen to this episode of Extend to understand why fertility is not only about having a baby. It may be one of the earliest windows into your health, your partner's health, and the health of the next generation.
