Obesity treatment in the form of bariatric surgery can reduce the incidence of migraines among severely obese people.
This is according to research conducted by Miriam Hospital, which has been published in the medical journal Neurology.
The researchers found that obese patients suffered from debilitating and painful migraines.
Obesity is defined as having a body mass index of 30 or above.
However, just six months after they underwent bariatric surgery, the people reported improvements in the frequency, severity and disability of their headaches.
During this time, the majority of patients had lost around 66 pounds in weight.
Lead author Dale Bond commented: "Obesity is thought to contribute to worsening of migraine, particularly for severely obese individuals, yet no study has examined whether weight loss can actually improve migraine headaches in these patients.
"Our study provides evidence that weight loss may be an important part of a migraine treatment plan for obese patients."
