The Shocking Link Between Your Gut & Mental Health – Fix This For Longevity | Dr. Mark Hyman

Ever notice how your stomach feels upset when you’re stressed or anxious? Turns out, your gut and your brain are best friends — they talk to each other all the time. And what’s happening in your gut can actually make your anxiety worse or better.

Sounds surprising, right? But it’s true. Your gut health and anxiety are closely connected, and taking care of your gut might be one of the easiest ways to calm your nerves.

Let’s break down what’s going on—and how you can start feeling better today.

Why Does Gut Health Matter for Anxiety?

Your gut is home to trillions of bacteria, both good and bad. This mix is called your gut microbiome. These tiny bacteria don’t just help you digest food—they send signals straight to your brain. Around 90% of your body’s serotonin (the hormone that helps you feel happy) is made in your gut, not your brain!

If the bad bacteria take over, they can cause inflammation and send stress signals to your brain, which can make anxiety worse. Studies have found that people with anxiety often have different gut bacteria compared to people without anxiety.

How Does a Troubled Gut Make Anxiety Worse?

Here’s what can happen if your gut is unhappy:

• Inflammation: Bad bacteria can irritate your gut lining. This inflammation sends signals to your brain that can increase anxiety.
• Stress Messages: Your gut talks to your brain, and a sick gut can send more “stress” messages than usual.
• Digestive Problems: If you often feel bloated, gassy, or have irregular bathroom visits, it can make you feel stressed. And stress makes these gut issues worse, creating a frustrating loop.

Signs Your Gut Might Be Fueling Your Anxiety

If you notice these symptoms, your gut might be playing a part in your anxiety:

• Frequent stomach pain or cramps
• Feeling bloated or uncomfortable after eating
• Constipation or diarrhea
• Anxiety that seems to flare up for no clear reason
• Feeling tired or having trouble sleeping

If this sounds familiar, focusing on your gut health could help.

Simple Ways to Help Your Gut and Calm Anxiety

The best part? You don’t have to make big changes overnight. Try these easy steps to support your gut and your mood:

1. Eat More Fiber and Fermented Foods

Fiber helps feed the good bacteria in your gut. Add more fruits, veggies, whole grains, and beans to your meals. Fermented foods like yogurt, sauerkraut, and kimchi add helpful bacteria too.

Curious about probiotics? This easy guide on probiotics explains how they work to keep your gut happy.

2. Cut Back on Sugar and Junk Food

Too much sugar feeds the bad bacteria and causes inflammation, which can upset your gut and your mood. Try to limit sweets, soda, and fast food.

3. Find Easy Ways to Manage Stress

Stress hurts your gut health, too. Even small things like deep breathing, a quick walk, or some quiet time can help you relax.

4. Get Enough Sleep

Sleep affects your gut bacteria and anxiety levels. Aim for 7 to 9 hours of good sleep each night to help your mind and gut recover.

5. Drink Plenty of Water

Water keeps digestion smooth and helps your gut stay healthy. Make sure to drink water throughout the day.
