Gastric bypass surgery can help alleviate migraine in the severely obese

5th April 2011

Severely obese patients who have undergone gastric bypass surgery may receive more health benefits than expected following surgery, according to a new study.

Scientists from Brown University and Miriam Hospital looked into the effects of gastric surgery on the reduction of migraines.

A small number of patients who underwent weight-loss surgery were investigated for the study, which was the first looking into this issue. They were given a 'migraine questionnaire before the surgery and again six months after to test the frequency of their headaches.

Almost half of the respondents reported a large reduction in the amount of severe headaches they suffered from, according to the study, which was published in the latest edition of Neurology.

It was also discovered that the drop in the number of headaches was directly linked to the amount of weight lost, with the biggest improvement seen in those who lost the most weight.

The study was based on the fact that migraine is more common in obese people than those of a normal weight. Women in particular suffer from severe headaches, nausea and other symptoms, yet nobody knows why this is the case.
