Migraines, Inflammation, and Your Genes

Why a Personalized Approach Matters

An interview with Dr. Amelia Scott Barrett, MD, by Dr. Elizabeth Yarnell, ND

Migraines are often minimized as “just headaches,” but migraine is a complex neurologic disease that involves the immune system, the gut, and the brain. For many people, inflammation plays a central role. What is often missing from the conversation is why inflammation behaves the way it does in one person versus another. That “why” is very often written into your genes.

If you are curious whether inflammation could be contributing to your migraines, and whether your genetics might help explain what is happening in your body, a good place to start is The Headache Quiz:

The quiz helps you explore whether inflammation, gut issues, or genetic factors may be part of your personal migraine pattern, and whether genetic testing could offer useful insight.

In this conversation, Dr. Elizabeth Yarnell, ND and Dr. Amelia Scott Barrett, MD explore why standard, one-size-fits-all migraine advice so often falls short. They discuss how unrecognized gut issues can drive ongoing inflammation, and how genetic differences influence how strongly the immune system reacts and how efficiently it settles back down. When people understand their genetic tendencies, symptoms that once felt confusing often begin to make sense, and decisions about food, supplements, and lifestyle become clearer and more grounded.

Inflammation and the Immune System

I often describe the immune system as a group of first responders. Their job is to recognize when something is wrong and send out a message asking for more help. Inflammation is that message.

In a healthy system, the message goes out, the issue is addressed, and the message stops. In many people with migraine, that message continues long after it should have quieted down. The immune system stays engaged, even when the original issue has passed, and that ongoing signaling can keep the nervous system in a sensitive, reactive state.

This tendency for inflammation to linger is frequently influenced by genetics. Some people are wired to produce stronger inflammatory signals or to have more difficulty shutting them off. That difference alone can shape how migraine shows up in the body.

The Gut–Immune Connection

One of the most important contributors to inflammation in migraine is the gut.

Many people with migraine sense that food matters, but they do not know why. They may notice bloating, discomfort, or inconsistent reactions that do not fit neatly into a single diagnosis. Often, there is an underlying gut issue that has never been fully identified.

When the gut lining is irritated or the microbiome is out of balance, the immune system receives constant signals that something is wrong. That ongoing communication can keep inflammatory pathways active and lower the brain’s tolerance for stress, sensory input, and pain.

Genetics again plays a role here. Some people are more prone to gut-driven immune activation, making them more sensitive to certain foods or environmental inputs, even when standard tests appear normal.

Why Avoidance Alone Is Not Enough

Avoiding inflammatory foods can be helpful, but it is rarely the entire solution.

Migraine inflammation is shaped not only by what enters the body, but also by how effectively the body can resolve inflammation once it begins. That process is genetically guided.

If your body struggles to shut down inflammatory signaling, simply avoiding triggers will not fully address the problem. In those cases, the goal becomes supporting the body’s ability to calm immune activity, repair the gut, and restore balance, rather than endlessly removing foods.

How Genetic Testing Brings Clarity

Genetic testing does not label or limit you. Instead, it provides context.

Your genetics can help explain:

• Why inflammation escalates easily

• Why certain foods affect you differently than others

• Why some supplements are helpful while others are not

For many patients, this understanding replaces years of trial and error with a clearer path forward.
