"In addition, it is unclear what is meant by complete, partial and no resolution, Loder said. "It would be very, very unusual for any treatment to cause complete resolution of migraine," she said.
Another expert, Dr. Richard B. Lipton, vice chairman of neurology, and director of the Montefiore Headache Center at the Albert Einstein College of Medicine in New York City, felt that the findings underscored the need for further research.
"These data are compatible with the epidemiologic studies showing that obesity is a risk factor for migraine progression," he said. "In addition, there is another published observational study showing that migraine improves after bariatric surgery in proportion to the extent of weight loss. Randomized trials are badly needed."
