The Root Causes of Hair Loss (And How to Reverse It) | Dr. Mark Hyman

Too often, we focus on treating symptoms without fully understanding the systems underneath them—or the conditions that allow the body to function well in the first place. On this episode of The Dr. Hyman Show, I sit down with Fidji Simo, CEO of Applications at OpenAI, to explore how AI could help us shift medicine from treating symptoms to restoring systems. We talk about why chronic illness is so often misunderstood, how health data has been fragmented across silos, and what becomes possible when we finally see the full picture. Watch the full conversation on YouTube or listen wherever you get your podcasts. In this episode, you’ll learn: • Why having a diagnosis doesn’t always explain what’s actually driving your symptoms • How connecting your labs, lifestyle data, and health history can reveal patterns you might otherwise miss • What it looks like to move from reactive care to proactive, personalized health • How better context can help you make clearer decisions about food, sleep, movement, and recovery Health isn’t built in a doctor’s office. When you create the right environment, the body often knows what to do—and understanding your own biology is one of the most powerful steps you can take toward creating health, not just reacting to disease.

For decades, we’ve been told that high cholesterol is the main driver of heart disease—and that lowering LDL should be the primary goal. But as science has evolved, so has my thinking. In today’s Office Hours, I explain why cholesterol alone doesn’t tell the full story, what most doctors still aren’t testing, and what’s really driving heart disease for the majority of people. Today we discuss: • Why many people have heart attacks despite “normal” LDL cholesterol • The difference between cholesterol levels and cholesterol particles • How inflammation and insulin resistance fuel heart disease • Why sugar and refined starches are more dangerous than fat • The most important labs to assess real cardiovascular risk • What ApoB, lipoprotein(a), and triglyceride-to-HDL ratio reveal about your health • How metabolic dysfunction—not cholesterol alone—drives plaque buildup Heart disease is far more complex than a single lab value. When you understand the role of metabolic health, inflammation, and the right biomarkers, you can take meaningful steps to protect your heart and long-term health.

Around the world, we’re seeing declining sperm counts, rising infertility, more erectile dysfunction, and lower testosterone—even in younger men. These trends aren’t just affecting family planning; they’re pointing to something much bigger happening in men’s health. Joining me today on The Dr. Hyman Show is Dr. Michael Eisenberg, a Stanford researcher and leading voice in male reproductive health. We talk about why sperm quality matters far beyond fertility—and how everyday health choices quietly shape it. Watch the full conversation on YouTube or listen wherever you get your podcasts. [YOUTUBE THUMBNAIL] We cover: • Why sperm quality may be one of the strongest early indicators of overall health and longevity • How metabolic dysfunction, belly fat, and low testosterone impact fertility and sexual function • The role environmental toxins and endocrine disruptors play in declining sperm counts • What men can do right now to protect fertility and long-term vitality When we look at fertility through the lens of whole-body health, it changes how we think about prevention, risk, and longevity. Male fertility isn’t just about reproduction. It’s a signal. Register for The Ultra Learning Series: Functional Fertility on Thursday, February 12 at 12PM ET here.

Here’s what I cover: • Why infertility is rising and what’s really driving it • The hidden role of blood sugar, inflammation, and toxins in hormone balance • What to do if labs are “normal” but fertility struggles persist • How lifestyle and nutrition improve egg and sperm quality • Simple, practical steps to support fertility now and long-term Fertility challenges are complex and often influenced by underlying imbalances.

On this episode of The Dr. Hyman Show, I sit down with Dr. Robert Hedaya, a psychiatrist who has spent decades working at the intersection of biology, brain function, and mental health. His approach starts with a different question than most psychiatry asks: what’s interfering with the brain’s ability to regulate, adapt, and repair itself? We talk about why many mental health diagnoses describe symptoms without explaining causes—and how measuring brain function, energy, and network activity is opening the door to more precise, individualized care. Watch the full conversation on YouTube or listen wherever you get your podcasts. [YOUTUBE THUMBNAIL] We discuss: • How biological imbalances can drive anxiety, depression, and cognitive symptoms • Why many “treatment-resistant” mental health issues have overlooked root causes • How brain energy and mitochondrial function influence mood and cognition • What advanced brain mapping reveals about how your brain is actually working For far too long, mental health care has focused on managing symptoms in isolation. This discussion looks at what becomes possible when we treat the brain as part of the whole system and support its ability to heal.
