Why do I get diarrhea during my period?

Many women frequently experience diarrhea during their menstrual period, sometimes accompanied by significant abdominal pain. So, what causes diarrhea during menstruation?

What Causes Diarrhea During Menstruation?

Diarrhea occurring during menstruation may be due to physiological changes. During the menstrual period, the female body releases large amounts of prostaglandins, leading to pelvic congestion. Prostaglandins further exacerbate pelvic congestion and stimulate intestinal spasms, impairing normal digestive function and resulting in gastrointestinal symptoms such as diarrhea and abdominal pain.

During menstruation, the body’s immune resistance declines. If unhygienic food is consumed, acute gastroenteritis may develop, causing diarrhea. If diarrhea is caused by menstruation-related physiological changes, no specific treatment is usually required. Menstrual-related diarrhea is also associated with pelvic congestion and uterine contractions. The pelvic nerves innervate both the uterus and the colon; thus, uterine contractions can trigger reflexive hypermotility of the intestines via neural pathways.

If diarrhea results from gastroenteritis, medical consultation is recommended. Blood tests and stool examinations should be performed, and antidiarrheal and anti-gastroenteritis medications should be administered under a physician’s guidance to prevent mild dehydration. For diarrhea occurring during menstruation, applying warmth to the lower abdomen, maintaining a light diet, drinking brown sugar–ginger tea for relief, avoiding late-night activities, and minimizing emotional stress are all advisable.
