Headache during menstruation is mainly caused by changes in hormone levels during menstruation. The concentration of estrogen in the body will change before and after menstruation, which will increase the sensitivity of intracranial vessels to serotonin, thus causing headache. In addition, another cause of headache is the release of prostaglandins in the body during menstruation. Prostaglandins are pain causing substances that not only cause headache, but also cause abdominal pain and lumbosacral discomfort. If the headache during menstruation is not serious, no special treatment is needed. Those with obvious headache can take NSAIDs appropriately. In addition, during menstruation, they should pay attention to rest, avoid cold, do not drink carbonated drinks and coffee, and avoid emotional fluctuations to alleviate pain and discomfort.
