Migraine and Migraine Triggers
Migraine is a throbbing headache (one- or both-sided) with nausea and sensitivity to lights and sounds, lasting from 4 to 72 hours. Migraine is considered as an inherited sensitivity of the nervous system resulting in dilation (expanding) of the arteries on the brain surface when triggered by certain stimuli (1).
Migraine triggers are stimuli that may increase a risk of having a migraine attack in a sensitive person. A certain migraine trigger does not necessary provoke migraine in all migraine sufferers, and not even always in the same person.
