Reasons for the connection between migraine and gas
Gut-Brain Axis: There is a very strong neural connection between the brain and the digestive system (via the Vagus nerve). Disturbances in the stomach affect the brain, which can trigger migraine pain.
Serotonin: Most of the hormone serotonin in the body is produced in the digestive system. Changes in serotonin levels can cause migraine pain and digestive disorders (gas, diarrhea).
Food allergies/sensitivities: Eating certain foods can cause migraines and affect digestion and cause gas. For example:
Dairy products (Lactose intolerance)
Foods containing gluten
Some types of artificial sweeteners
Migraine medications: Some medications used to reduce migraines can damage the digestive system and cause gas, constipation, etc.
Lifestyle: Excessive mental stress (Stress) is a major cause of migraines. This same stress slows down digestion and causes gas problems.
Dietary habits/skipping: Not eating food at the right time can cause gas, which can later lead to migraine pain.
