Migraine and gut health

This is not a fringe idea. The gut and the brain are in constant communication through nerves, hormones and the immune system, and most of the body's serotonin is made in the gut rather than the head. That connection is real and well established.

It shows up in the numbers too. People who get migraines are more likely than others to also have irritable bowel syndrome, constipation, reflux, coeliac disease or inflammatory bowel disease. The two travel together often enough to be worth noticing.

For some people, and particularly for those who have digestive symptoms alongside their headaches, looking after gut health does seem to reduce how often migraines come. Some studies on particular probiotic strains point the same way, though the findings are mixed and none of this is standard treatment.

So it is a reasonable thing to work on, especially if your stomach is troubling you anyway. It is not a cure and should not be treated as one.

You will see it said that migraine is largely a gut problem. That is stronger than the evidence supports, and believing it can lead people away from things that would help them more.

Migraine is a neurological condition with a strong family component. Hormonal changes, poor sleep, stress, dehydration, skipped meals, certain medicines, bright light and individual food triggers all play their part, and for many people one of those matters far more than digestion does.

The honest version is this: gut health is one piece of the migraine puzzle, not the whole puzzle. Worth attending to, unlikely to be the answer on its own.

The things that support gut health are things worth doing regardless: plenty of fibre from vegetables, fruit, beans, lentils and whole grains, a variety of plant foods across the week, fermented foods if they suit you, less ultra-processed food, regular movement, decent sleep and some handle on stress.

For migraine specifically, the unglamorous basics tend to do more than anything exotic. Eat regularly rather than leaving long gaps, keep hydrated, protect your sleep, and keep a simple diary for a few weeks to find your own patterns rather than working from someone else's trigger list.

This is general food and lifestyle guidance, not medical advice. Headaches that are new, severe, different from your usual pattern, or coming with other symptoms should be seen by a doctor rather than managed from a website.
