Both obesity and being underweight are associated with an increased risk for migraine, according to a meta-analysis published in the April 12, 2017, online issue of Neurology®, the medical journal of the American Academy of Neurology. The researchers looked at all available studies on body mass index (BMI) and migraine.

The researchers looked at all available studies on body mass index (BMI) and migraine.
“As obesity and being underweight are potentially modifiable risk factors for migraine, awareness of these risk factors is vital for both people with migraine and doctors,” said study author B. Lee Peterlin, DO, of Johns Hopkins University School of Medicine and a member of the American Academy of Neurology. “More research is needed to determine whether efforts to help people lose or gain weight could lower their risk for migraine.” A total of 12 studies with 288,981 participants were included in the meta-analysis. When the researchers compiled all of the results and adjusted for age and sex, they found that obese people were 27 percent more likely to have migraine than people of normal weight. People who were underweight were 13 percent more likely to have migraine than people of normal weight. Obesity was defined as a BMI of 30 or higher. Underweight was defined as a BMI of less than 18.5.
