Is migraine associated with iron deficiency?
In the magazine Headache published a study on the type of migraine, often annoying many women. This is a headache that occurs at the end of menstruation. Previously, it did not stand out as an independent form, but was considered as one of the manifestations of migraine. The study involved 30 women who have headaches at the end of menstrual bleeding. At the same time, they found a low level of iron in the blood, which led scientists to think about the possible effectiveness of iron supplementation. Scientists suggest that migraine at the end of menstruation is not associated with the hormonal background, but depends on blood loss during menstruation, leading to a transient transient anemia that causes migraines. More common type of migraine is traditionally associated with hormonal causes, it is aggravated 1-2 days before or in the first 1-2 days of the menstrual cycle. And its manifestations are considered associated with a decrease in the level of estrogen. This kind of migraine can be treated with hormones. But there are cases and combinations of these two types of migraine, when a woman complains of a headache both before menstruation, and throughout her days. The number of such patients reaches 20%. Scientists noted that migraine in women often combines with restless legs syndrome, which usually reveals a low level of ferritin. Of the 30 women examined, 28 had a low ferritin level. Despite the fact that such patients receive iron supplements, the problem requires further study, since in addition to iron deficiency, the provoking factor can also be the release of prostaglandins, accompanying profuse and painful periods. In these cases, therapeutic tactics should be different, blockers of prostaglandins are indicated.
