The Dr. Hyman Show

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 the gut and microbiome to inflammation, nutrient deficiencies, blood sugar, hormones, and the foods we eat. Because the brain doesn’t operate in isolation. What happens throughout the body can directly influence how it functions. Here’s what we discuss in today’s episode: The surprising connection between your gut and your ability to focus—even if you have no digestive symptoms What I look for beyond the brain when someone comes to me with ADHD The everyday foods and nutrient deficiencies that may be quietly making ADHD symptoms worse Why two people with the same ADHD diagnosis may have completely different underlying drivers What caffeine, skipping breakfast, food dyes, sugar cravings, and menopause may mean for ADHD symptoms Where I would start if an adult came to me newly diagnosed with ADHD ADHD may begin with symptoms in the brain, but that doesn’t mean the brain is the only place we should look. By understanding the connections between diet, gut health, inflammation, nutrients, hormones, and brain function, we can start asking a more useful question: What is making it harder for each person’s brain to function at its best?

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, to explore what she calls the frantic-crash cycle. She explains how chronic fight-or-flight may intensify ADHD symptoms and why nervous system regulation can make other tools and strategies easier to use. You’ll learn: Why women and high achievers can compensate for ADHD for decades before their usual coping strategies stop working How perfectionism, procrastination, and working under pressure can keep the frantic-crash cycle going The physical signs of nervous system dysregulation, including shallow breathing, muscle tension, and rushing even when there’s no real urgency Why calming your body is only the first step in creating lasting change How you can move away from all-or-nothing behavior and build a more sustainable way of getting things done A diagnosis can help you understand how your brain works, but it doesn’t have to define what’s possible. By learning to recognize and regulate survival mode, you can create the conditions for your brain to work at its best.

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 and heart disease to arthritis and cognitive decline. Here’s what I unpack in today’s episode: The hidden “inflammation switch” scientists are studying and why it may help explain how chronic inflammation drives aging and disease The everyday habits that can keep your immune system stuck in a constant state of alarm The surprising connection between mitochondrial health, visceral fat, blood sugar, and inflammation The most effective ways to help calm chronic inflammation and the simple daily shifts that may have the biggest impact Inflammation isn’t the enemy—it’s one of your body’s most important survival tools. The problem is when the alarm never switches off. By changing the signals you send your immune system every day, you can help restore balance and support healthier aging from the inside out.

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 the brain as we age. You’ll learn: Why protecting your brain should begin long before memory problems appear How your daily choices influence whether the brain’s immune cells shift into a protective or damaging state Which numbers to know now, including fasting insulin, blood sugar, and waist-to-hip ratio How food, exercise, sleep, gut health, and environmental toxins shape your brain’s future What emerging research reveals about slowing—and even improving—cognitive decline I’ve always appreciated how David’s work replaces fear with something far more useful: a clearer understanding of how the choices we make today can help protect our memory, independence, and quality of life for years to come.

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 inside out The surprising connection between muscle, metabolism, and firmer, healthier-looking skin (especially after weight loss) How your body's natural cellular repair system helps slow the aging process and the habits that activate it The biggest everyday factors accelerating skin aging, and the science-backed strategies that help protect your skin for years to come Healthy skin isn't something you can simply apply—it's something your body creates. By improving your metabolic health, protecting collagen, building muscle, reducing inflammation, and supporting your cells, you can help your skin stay stronger, healthier, and more resilient from the inside out.
