Menstruation the 3rd day still is in dysmenorrhea what reason is loose bowels again

Dysmenorrhea is a common symptom of female menstruation. Dysmenorrhea accompanied by diarrhea is caused by a large amount of prostaglandin secreted by the uterus. Prostaglandins can cause abdominal pain due to uterine smooth muscle spasm. At the same time, they can also act on intestinal smooth muscle, causing diarrhea symptoms to increase. It is recommended to use hot water bags or towels for local hot compress to help relieve pain.
