Bacteria can trigger migraine

A new study suggests that bacteria from the food left in the mouth may cause migraines.

The study, published this week in the American Society for Microbiology’s open-access journal mSystems, found that people who got migraines had more bacteria in their mouths than others.

Too much of bacteria may break down nitrates more quickly, causing blood vessels in the brain and scalp to dilate, thus causing migraines, a related research said.

Doctors suggest avoiding foods like aged cheese, salty foods, processed foods and food additives like aspartame and MSG.

Alcohol and caffeine may also trigger migraines.
