In an April 2017 meta-analysis by Johns Hopkins University School of Medicine, it was found that, “Both obesity and being underweight are associated with an increased risk for migraine.

B. Lee Peterlin said, “age and sex were important variables in the relationship between body mass index and migraine” adding, "This makes sense, as the risk entailed by obesity and the risk of migraine is different in women and men and in younger and older people … Both obesity disease risk and the occurrence of migraine is more common in women and in younger people."
