Obese people are more likely to suffer from more frequent and severe migraine headaches. The question that remained unanswered was whether losing weight helps relieve headaches. A new study just published in the leading neurology journal, Neurology suggests that this may be the case. Researchers from Brown University in Providence, RI examined 24 severely obese patients before and after bariatric (weight reduction) surgery. Their mean body mass index (BMI) was 46 and their mean age was 39. A direct correlation between the amount of weight loss and the reduction in the number of headache days was observed. Weight loss was also associate with reduced disability. This study gives scientific support to the idea that weight loss may improve migraine headaches.

An interesting study by Dr. Bigal and his colleagues, just published in Cephalalgia looked at this effect of drugs in 331 patients. They found that 16% of them gained weight (5% or more of their baseline weight) and 17% lost weight. The various treatments given to these patients were equally effective in both groups. However, not surprisingly, those who gained weight had elevation of their cholesterol, blood glucose, blood pressure and pulse. Patients who have migraine headaches with aura (about 15-20% of migraine sufferers) already have an increased risk of strokes, so adding additional risk factors for both strokes and heart attacks should be especially avoided in this group. The only preventive migraine drug which consistently lowers weight in many patients is topiramate (Topamax). This drug is now available in a generic form, making it much less expensive. While topiramate does lower weight and helps prevent migraine headaches only half of the patients stay on it. For the other half it causes unpleasant side effects (memory impairment and other) or it does not work.
