HealthDay News — Weight – both overweight and underweight – may influence risk of migraine headaches, according to a review published online April 12 in Neurology.

B. Lee Peterlin, DO, director of headache research at the Johns Hopkins University School of Medicine in Baltimore, and colleagues evaluated 12 previously published studies with 288,981 unique participants.
