When most people think of migraine triggers, they think of stress, hormones, sleep patterns, or changes in the weather. But there’s another important—and often overlooked—factor: gut health.

At Migraine Relief Center, we believe in treating the whole person, not just the pain. That’s why we pay attention to emerging research and patterns in patient care. One area that’s getting more attention lately? The gut-brain connection and its impact on migraine frequency and severity.

What Is the Gut-Brain Connection?

Your gut and brain are in constant communication. This system—called the gut-brain axis—involves a complex network of nerves, hormones, and biochemicals that allow the digestive system to send signals to the brain, and vice versa.

When your gut is out of balance due to inflammation, poor diet, or stress, those distress signals can contribute to neurological symptoms—including migraines.

How Gut Health Can Affect Migraine Patterns

Here are a few ways your digestive health may be influencing your headaches:

1. Chronic Inflammation

An unhealthy gut can cause low-grade inflammation throughout the body. This inflammation may sensitize your nervous system and lower your threshold for migraine attacks.

2. Microbiome Imbalance

Your gut is home to trillions of bacteria that support immune health, digestion, and even mood. Imbalances in these bacteria (called dysbiosis) have been linked to increased migraine activity in some studies.

3. Food Sensitivities

Certain foods—like aged cheeses, chocolate, processed meats, and artificial sweeteners—are known migraine triggers for many people. These same foods can also disrupt gut health, leading to a double whammy.

Signs Your Gut Might Be a Migraine Trigger

• Frequent bloating, constipation, or digestive discomfort

• Headaches that follow certain meals

• A history of antibiotic use or poor diet

• Migraines worsened by stress (which affects gut function too)

If any of these sound familiar, your gut might be sending signals your brain is interpreting as pain.

What You Can Do

Improving gut health doesn’t require a complete diet overhaul overnight. Start small:

• Eat more whole foods like fruits, vegetables, legumes, and fermented foods

• Avoid skipping meals, which can trigger both migraines and digestive stress

• Stay hydrated

• Limit processed foods and added sugars

• Consider keeping a food and symptom journal to identify patterns

And most importantly—don’t try to figure it out alone. Every person’s triggers and biology are different. What helps one person might not help another.
