The most common type of dysmenorrhea is primary dysmenorrhea, which may be as painful as childbirth, but there is no organic disease in the body. The pathogenesis of primary dysmenorrhea is that women produce prostaglandins during menstruation, which stimulate the contraction of the smooth muscles of the uterus. Since the gastrointestinal wall also has smooth muscles, it will also be stimulated at the same time, so some girls vomit during dysmenorrhea, which is a manifestation of gastrointestinal spasm. During menstruation, large chunks of the endometrium are shed, blocking the cervical opening. The uterus will react naturally and strengthen contraction to expel it, causing pain, which is also one of the pathogenesis of dysmenorrhea. Girls with narrow cervical openings are especially prone to dysmenorrhea.

Mental factors are actually the pathogenesis of primary dysmenorrhea in sensitive girls. When mental stress is high, such as when studying, some girls will have dysmenorrhea, and the pain will go away after they relax. Primary dysmenorrhea usually does not last long. It is often very painful on the first day of menstruation, and it will ease within a few hours to 24 hours. Most girls have primary dysmenorrhea, which gradually disappears with age after childbirth or marriage.
