Migraine Risk May Be Tied to Body Weight
The exact cause for migraine is not yet fully understood, and although several treatments are available, an absolute cure has not been discovered. A new analysis of existing research examines the potential link between migraines and body weight—specifically how being underweight, overweight, or obese can affect migraine risk.
For their analysis, researchers compiled information and examined results from 12 studies, involving about 290,000 participants. They found that people with obesity—defined as having a body mass index (BMI) greater than 30—had a 27 percent higher risk of migraine, and those who were underweight—BMI below 18.5—had a 13 percent higher migraine risk than people who were normal weight.
Because this study was observational—and some information was reported by the participants and may have been inaccurate—it does not prove a definitive link between migraine headaches and body weight. However, maintaining a healthy weight, getting enough sleep and exercise, and reducing stress have all been shown to decrease migraine symptoms.
