Dysmenorrhea is mainly divided into primary dysmenorrhea and secondary dysmenorrhea. Primary dysmenorrhea is more common in adolescence, so students' dysmenorrhea is mostly primary dysmenorrhea, which is mainly related to the increase of prostaglandin content in endometrium during menstruation. The symptoms of pain can appear as early as 12 hours before today, and the pain is the most severe on the first day of menstruation. Generally, this kind of pain will be relieved after two to three days. The treatment of dysmenorrhea can be divided into general treatment and drug treatment.

General treatment mainly refers to emotional counseling, relieving tension, ensuring adequate sleep, moderate exercise, quitting smoking and keeping warm. Drug treatment mainly refers to oral ibuprofen 200-400 mg, three or four times a day, or oral ibuprofen 50 mg, three times a day. Oral short-acting contraceptives, such as Marvelon or Yasmin, can reduce the contents of menstrual blood and prostaglandin by inhibiting ovulation.
