Scientists from France, who analyzed the data obtained in the course of a long-term study, obtained a very unexpected result. It turned out that women suffering from migraines are much less likely to develop diabetes.
Is it possible to find at least something good in a migraine, from which, strictly speaking, one headache? Oddly enough, the answer to this question is positive. Women suffering from this neurological disease have a lower risk of developing diabetes mellitus - this was the conclusion made by a group of scientists led by Guy Fagerazzi, a senior researcher at Digital & Diabetes Epidemiology, who analyzed a huge amount of statistical data.
The article, published in the journal JAMA Neurology in the second half of December, published the results of this large-scale work. The authors of the material Associations Between Migraine and Type 2 Diabetes in Women ("The Correlation between Migraine and Type 2 Diabetes in Women") initially used health information obtained in 1990 during a survey of French women born between 1925-1950 years (98 995 people took part in it).
Then they studied the data of eligible women who completed the 2002 questionnaire, which also contained a paragraph on migraine (76 403 French women did). After that, 2 156 diabetologist patients were excluded from the sample.
Thus, at the beginning of the study, none of the remaining 74,247 women (their average age was 61 years old) suffered from type 2 diabetes. Over the following years of observation, 2 372 of them were diagnosed with type 2 diabetes.
A lower risk of developing type 2 diabetes was observed in women with active migraine compared with women without a migraine in history.
Scientists also noted that the number of migraine attacks in those women who were eventually diagnosed with type 2 diabetes decreased from 22% to 11% a few years before the diagnosis was made.
So far, researchers can not explain what specific mechanisms underlie this relationship. But they suggested that the results may indicate a potentially important role of both hyperglycemia and hyperinsulinism in the incidence of migraine, because with elevated blood sugar levels leading to type 2 diabetes, migraine symptoms may decrease.
