When menstrual cramps occur, the uterus contracts violently, stimulating gastrointestinal motility and easily causing gastrointestinal reactions such as nausea and diarrhea. It is common in women with poor spleen and stomach function, or deficiency of qi and blood, and stagnation of qi and blood. Diarrhea symptoms can be relieved by drinking ginger brown sugar water, or fried rice water, which is the upper layer of water after frying rice. At the same time, the abdomen should be warmed and the spleen and kidneys should be warmed to treat diarrhea. After the symptoms are relieved, you should go to a regular hospital for timely adjustment, as dysmenorrhea diarrhea is a medical condition rather than an ordinary physiological phenomenon. Chinese herbs can be taken continuously for 2-3 months to regulate menstruation and the spleen and stomach.
