The causes of heavy stools during menstruation usually include changes in hormone levels, endometriosis or pelvic inflammatory disease, etc. It may also have nothing to do with menstruation as it is caused by intestinal inflammation, so if it is accompanied by significant discomfort seek medical treatment in a timely manner.
1. During menstruation, female hormone levels will change, due to pelvic congestion and the role of prostaglandins during menstruation, some women experience discomfort in the lower abdomen and lumbar-sacral area or uterine contraction pain, and diarrhea and other gastrointestinal dysfunction symptoms, which leads to an increase in stools.
2. Patients with endometriosis may also have increased bowel movements during menstruation, especially in the deep nodular type, where the lesions are usually located in the gap between the vagina and the rectum, and bleeding from the lesions during menstruation may irritate the rectum and cause increased bowel movements.
3. Pelvic inflammatory disease may be aggravated during menstruation, which may lead to an increase in pelvic fluid, discomfort in the lower abdomen, a strong desire to defecate, and a feeling of incomplete defecation after defecation.
Increased bowel movements during menstruation may also not be related to menstruation, and there may be other conditions, such as enteritis. If there is a significant increase in the number of stools, dilute, accompanied by significant abdominal pain and discomfort, etc. should be promptly consulted.
