Martin’s two-part review, “Diet and Headache” is available online in the scholarly publicationHeadache: The Journal of Head and Face Pain. It is co-authored by Dr. Brinder Vij, associate professor in the UC Department of Neurology and Rehabilitation Medicine.
“One of the most important triggers for headache is the withdrawal of caffeine,” says Martin, who also sees patients at UC Health. “Let’s say you regularly pound down three or four cups of coffee every morning and you decide to skip your morning routine one day, you will likely have full-fledged caffeine withdrawal headache that day.”
That said, too much coffee may also present a risk, no more than 400 milligrams daily–one cup is 125 milligrams–is probably the maximum for migraine patients, says Martin. “Large amounts of caffeine can bring on anxiety and depressive symptoms as well as headaches,” he explains.
