Alcohol is a migraine trigger, but its risk overstated. Alcohol can provoke two types of headache in migraine patients: an attack within a few hours and a delayed hangover headache. Migraine patients consume alcohol less often than the general public.
Alcohol has long been associated with the development of headache, with about one-third of patients with migraine noting alcohol as a trigger. Based on this association, population studies show that patients with migraine tend to drink alcohol less often than people without migraine.
