How is the abdomen painful before menstruation to return a responsibility

Abdominal pain before menstruation is considered to be caused by dysmenorrhea. Dysmenorrhea can be divided into primary dysmenorrhea and secondary dysmenorrhea. Primary dysmenorrhea is mainly related to the increase of prostaglandin content in the body. When the prostaglandin content in the body increases, it is easy to cause excessive contraction of uterine smooth muscle, resulting in uterine ischemia, resulting in dysmenorrhea. Secondary dysmenorrhea is mainly related to gynecological diseases such as adenomyosis.
