Difficulty in defecation during menstruation may be related to physiological reasons such as hormonal changes during menstruation, or pathological reasons such as endometriosis and gastrointestinal disorders, which need to be analyzed.
1. Physiological reasons: Changes in hormone levels during menstruation will cause pelvic congestion, resulting in lower abdominal pain with a sensation of bloating, and sometimes there will be a feeling of wanting to defecate, but the actual defecation is not possible, which may also be a normal physiological phenomenon.
2. Endometriosis: when the endometrium is ectopic to the pelvic cavity, especially the uterine rectal fossa, there will be strong stimulation to the rectum during menstruation, and this stimulation will trigger a local non-inflammatory reaction, and there will be a strong feeling of defecation, but the bowel movement will not come out.
3. Gastrointestinal dysfunction: Gastrointestinal dysfunction will lead to slow intestinal peristalsis, food in the intestinal tract storage time is too long, excessive absorption of water in the feces will lead to dry stools, while intestinal motility function is reduced, resulting in difficulties in the discharge of stools.
There may be other reasons why a woman may have difficulty passing stool when she is menstruating, so it is recommended that a relevant examination be conducted and targeted treatment measures be taken.
