The Dr. Hyman Show

Your doctor says your blood sugar is normal, so you assume everything is fine. But what if your body is already showing signs of insulin resistance and your routine blood tests aren't catching it? Today, I break down what your blood sugar numbers actually reveal, the critical markers most doctors aren't testing, and how to spot metabolic dysfunction before it develops into something more serious.

Here's what we discuss in today's episode:

• Why normal blood sugar doesn't necessarily mean you're metabolically healthy
• The overlooked blood test that may reveal insulin resistance years before your glucose rises
• What your fasting glucose, insulin, and A1c numbers actually mean and what to look for
• How sleep, stress, meal timing, and even the order you eat your food can affect blood sugar
• The surprising signs of insulin resistance, even in people who appear thin and healthy
• Simple changes you can make today to improve your metabolic health

Insulin resistance can develop silently for years before showing up on a standard blood test. The sooner you understand what's happening in your body, the sooner you can take action. And the good news is that many of the most powerful ways to improve your metabolic health start with simple, everyday habits.

How well is your brain aging? Your birthday tells you one thing, but your brain may tell a different story.

Today, I’m talking with neuroscientist Paul Thompson, PhD, whose work with the global ENIGMA Consortium is revealing how brain health connects to what’s happening throughout your body. We get into what brain scans can tell us and why those findings matter to you.

We discuss:

• What your “brain age” means and how it can differ from your actual age

• Why your metabolic health deserves attention when you’re struggling with mood or memory

• How sleep and nutrition support your brain’s ability to function and recover

• What having an Alzheimer’s risk gene does, and doesn’t, tell you about your future

• How brain scans, blood tests, and AI could help identify the right treatment for you

It’s so exciting to see researchers like Paul looking across thousands of brain scans and uncovering connections between the health of the body and the brain. For me, it opens up a bigger conversation about how we care for ourselves and how our everyday habits can help protect our memory and support our mood as we age.

In this episode, I'm joined by Dr. Boham, Medical Director of the UltraWellness Center, to explore why breast cancer develops, the hidden factors that may influence your risk, and what you can do to be proactive about prevention—not just early detection.

Here's what we discuss in today's episode:

• Why breast cancer is increasingly being diagnosed in younger women
• The overlooked factors that may influence breast cancer risk beyond genetics and family history
• How your gut health, hormones, and environmental exposures may be connected to breast cancer
• What women should know about hormone replacement therapy and breast cancer risk
• The screenings, tests, and everyday habits that can help you take a more proactive approach to breast health

While we can't prevent every case of breast cancer, there are meaningful steps we can take to influence our health. Understanding your individual risk and addressing the factors within your control can help you make more informed decisions about prevention and long-term wellness.
