The cross-sectional study doesn't prove that obesity causes episodic migraines, but it does demonstrate that people who are obese have an increased risk of having more of them, even low-frequency ones, said lead author Dr. Barbara Lee Peterlin, director of headache research at Johns Hopkins University School of Medicine, in Baltimore.
Adipose tissue secretes different inflammatory proteins based on how much tissue there is and where it is located. Since younger women and obese people have more adipose tissue, this could, at least in part, explain why they get more headaches.
