The pathogenesis of migraine is not clear yet, but it may be related to vasoconstriction and dilation dysfunction, abnormal secretion of certain neurotransmitters in the brain, such as 5-hydroxytryptamine, and disturbance of trigeminal nerve regulation mechanism. Although the pathogenesis is not clear, there are many triggers, among which milk is a common trigger, in addition to blowing wind, getting cold, staying up late and bad mood can trigger migraine. Patients with migraine should try to avoid triggers. If migraine occurs after drinking milk, patients should try to avoid drinking milk and other dairy products, including yogurt, cheese, ice cream and cakes.
