A normal mammogram can bring a real sense of relief. But when it comes to understanding your breast cancer risk, what else should you know? Today, I’m joined by OB/GYN and SHE MD podcast co-host Dr. Thaïs Aliabadi. Helping women get answers about their health has been central to her work for decades. Yet when she faced her own breast cancer diagnosis, she experienced the same dismissal so many of...

What if the fatigue, brain fog, bloating, and cravings you've accepted as normal are actually signs that something you're eating isn't working for your body? You may not realize how much your food is affecting you until you change it. In this episode, I break down why I created the 10-Day Detox, what happens inside your body when you remove common dietary triggers, and how just 10 days can reveal...

Early in my career, I noticed that patients’ skin often improved as we addressed their nutrition and gut health. That changed how I approached skin concerns and taught me to look beneath the surface for contributing factors. Today, I’m joined by triple board-certified dermatologist Dr. Mamina Turegano, co-author of The Holistic Psoriasis Management and Nutrition Guide and an advocate for Timeline’...

Why do some people catch every cold going around while others rarely get sick? Your immune system isn’t something you simply “boost” with one supplement—it’s shaped every day by your sleep, diet, stress, gut health, nutrient status, and metabolic health. In this episode, I’m joined by one of my producers, Emma, to break down what actually helps you build a more resilient immune system before cold...

Nutrition advice often reduces food to calories, nutrients, and a list of rules to follow. But the more we learn about how the body responds to different foods, the clearer it becomes that this way of thinking tells only part of the story. Today, I’m joined by cardiologist and public health expert Dr. Dariush Mozaffarian, director of the Food is Medicine Institute at Tufts University and author of...

In this episode, I break down five popular longevity myths that may be distracting you from the things that actually have the biggest impact on how long and how well you live. Here’s what I discuss in today’s episode: The common longevity goal that may actually work against you as you get older Why the “perfect” supplement stack can’t replace the habits that matter most The mistake people make whe...

You can know exactly how you want to eat and still find yourself reaching for something else when you’re stressed or exhausted. I’ve been there. Our relationship with food is influenced by far more than nutrition knowledge, and blaming ourselves for struggling doesn’t help us understand what’s actually happening. Today, I’m joined by clinical psychologist Dr. Rachel Goldman, author of When Life Ha...

Trying to eat healthy has gotten surprisingly complicated. You pick up salmon and wonder about mercury, grab strawberries and think about pesticides, or drink from a plastic bottle and start worrying about microplastics. But not every food-safety risk deserves the same level of concern. In this episode, I break down what actually matters, what’s worth paying extra for, and the simple changes that...

Chronic illness rarely fits neatly into a single diagnosis. Symptoms can span multiple systems, leaving people profoundly unwell even when standard testing appears normal. I understand this experience from the inside out because I’ve lived it myself. Today, I sit down with Dr. Neil Nathan, a leading expert in complex chronic illness and author of Toxic, now in its second edition. We explore why th...

Brain fog isn’t just a normal part of getting older—and it may not be a brain problem at all. If you struggle to focus, lose your train of thought, forget why you walked into a room, or feel mentally exhausted after eating, your body may be trying to tell you something. Here’s what I discuss in today’s episode: The five foods I most commonly see contributing to brain fog—and why some seemingly “he...

This week, I’m the one answering the questions in a deeply personal conversation about my health journey. I speak openly about some of the hardest parts of that journey, the treatments I’ve tried, the beliefs I’ve reconsidered, and what a lifetime devoted to health has taught me about what matters most. Here’s some of what I share: How becoming the patient changed the way I practice medicine How n...

With the Labour Day long weekend here, we’re bringing back one of our most popular Office Hours episodes on what really happens to your body when you take a break from alcohol. Whether you’re drinking less this weekend or simply curious about how quickly your body can recover, this conversation is worth revisiting. Today I discuss: What alcohol really is—and why the “buzz” is actually your brain s...

We hear a lot about improving gut health through food, probiotics, and supplements. But after more than a decade of major advances in microbiome research, the picture has become both more promising and more complex. In this episode, I’m joined by gastroenterologist and neuroscientist Dr. Emeran Mayer, co-author of the new book The Mayer Model, to explore how our understanding of the gut-brain conn...

ADHD is usually treated as a problem in the brain. But what if some of the factors making it harder to focus, regulate your mood, or manage your symptoms are actually coming from somewhere else in your body? In this episode, I’m joined by one of my producers, Emma, to explore ADHD through a functional medicine lens. We look beyond the diagnosis to ask what may be happening “under the hood”—from th...

ADHD can go unnoticed for decades, especially in women who learn to compensate through perfectionism, overpreparing, and working under pressure. It often isn’t until the demands of work, motherhood, or another major life transition become too much that the underlying struggle comes into view. In this episode, I sit down with ADHD counselor Jenna Free, author of The Simple Guide to ADHD Regulation,...

Chronic inflammation may be one of the biggest forces accelerating how we age—and the surprising part is that many of the things keeping it switched on are happening every day. Poor sleep, chronic stress, blood sugar spikes, visceral fat, and ultra-processed food can keep your immune system acting like it’s under constant threat, potentially contributing to everything from metabolic dysfunction an...

By the time memory begins to slip, the changes affecting the brain may have been developing for decades. But the trajectory isn’t fixed, and many of the factors driving it are within our control. In this episode, I sit down with my longtime friend and mentor Dr. David Perlmutter, six-time New York Times bestselling author whose new book, Brain Defenders, rethinks what it really takes to protect th...

Healthy skin isn't built in your bathroom—it’s built inside your body. While most people focus on creams, collagen powders, and cosmetic treatments, the biggest drivers of wrinkles, sagging, and loss of elasticity are happening at the cellular level. In today's episode, I discuss: Why blood sugar may be aging your skin faster than the sun and the hidden process that damages collagen from the insid...

GLP-1 medications have changed how we treat obesity and metabolic disease. But as their use has exploded, so have questions about side effects, muscle loss, long-term use, and whether patients are receiving the support they need to use them safely. In this episode, I reconnect with metabolic health and regenerative medicine expert Dr. Tyna Moore to revisit our conversation from two years ago and e...

The number on your scale tells you almost nothing about your actual health. You can lose weight while becoming less healthy—or stay the same weight while dramatically improving your metabolism, reducing your risk of disease, and adding years to your life. In today's episode, I discuss: Why the scale can completely miss what's happening inside your body and the hidden health risks it can't measure...

Heart disease is still the leading cause of death worldwide. Yet many people assume it only happens to those who are older, out of shape, or obviously unhealthy. In this episode, I sit down with cardiovascular surgeon Dr. Jeremy London, whose own heart attack challenged many of the assumptions we make about heart health. We discuss why prevention isn't always as straightforward as it seems—and how...

What if one of the most powerful anti-aging tools wasn't a supplement, medication, or expensive biohack—but the way you exercise? While many people think of exercise as a way to lose weight or burn calories, its greatest benefits happen deep inside your cells. In today's episode, I discuss: The two most effective forms of exercise for healthy aging and longevity What happens inside your cells when...

Living with chronic illness can feel like collecting diagnoses without getting real answers. Symptoms are treated one at a time, but the underlying causes can easily be missed. What if asking a different question is the first step toward feeling better? In this episode, I’m joined by Dr. Richard Horowitz, an internationally recognized Lyme disease expert and author of the new book Ending Chronic I...

What if the fatigue, brain fog, joint pain, or mysterious symptoms you've been chasing for years weren't caused by stress, aging, or burnout—but by a tick bite you never even noticed? Lyme disease is one of the most misunderstood illnesses in medicine. But Lyme is rarely just one infection—it's often part of a much bigger picture involving co-infections, immune dysfunction, inflammation, gut healt...

For decades, depression has often been described as the result of a chemical imbalance in the brain. But how strong is the evidence behind that idea? This episode explores one perspective on an area of medicine that continues to be actively debated and is intended to encourage thoughtful discussion—not to provide individualized medical advice. Today on The Dr. Hyman Show, I'm joined by psychiatris...
