Primary dysmenorrhea has a high incidence in junior and senior high school adolescents and is a common condition in adolescent girls. Some of the dysmenorrhea is mild and does not affect daily life much, but some of them have severe pain and must take painkillers, which seriously affects daily life and study. Every year, before the entrance exams, there are always parents of patients with dysmenorrhea who seek medication to delay menstruation because they are afraid that their children’s menstrual periods will coincide with the entrance exams. The drug postpones menstruation, in fact, is the use of progesterone (progestin) to extend the luteal phase, and finally the formation of drug withdrawal bleeding, but to achieve the purpose of artificial control of the date of menstruation. This can really slow down the momentary emergency, but there are also because of the menstruation is not very regular, or did not master the time to take the drug, and failed to postpone. There are also cases of menstrual disorders after the use of drugs to postpone menstruation. Therefore, medication is not a good way to delay menstruation. Minor abdominal pain or discomfort during menstruation can be left untreated if it does not affect daily life and study, but severe dysmenorrhea should receive treatment. Western medicine treats dysmenorrhea, mostly with prostaglandin synthase inhibitors (painkillers), or with birth control pills (ovulation suppression). Chinese medicine, on the other hand, treats dysmenorrhea on the basis of evidence-based treatment, and generally requires treatment for three menstrual cycles, the majority of which can be cured. Therefore, proactive treatment of dysmenorrhea can not only reduce the monthly pain of dysmenorrhea patients, but also avoid the psychological and physiological adverse effects caused by the temporary postponement of menstruation for students who are about to take secondary and high school exams.
