Why do I always feel the urge to defecate, but only a little comes out each time?

Every time I want to have a bowel movement, I can only pass a little bit out, which may be due to some intestinal diseases, such as indigestion, irritable bowel syndrome, colitis, rectal or sigmoid colon abnormalities, slow intestinal movement, etc. These diseases may lead to abnormal bowel movements, so targeted treatment needs to be combined with specific diseases.

Many intestinal diseases can easily lead to abnormal bowel movements, such as irritable bowel syndrome. This disease may lead to indigestion and intestinal flora imbalance due to dysfunction of the autonomic nervous system. In addition, it is also seen in chronic intestinal inflammation, such as chronic ulcerative colitis and Crohn's disease.

Abnormalities in the rectum or sigmoid colon may also cause the symptoms of always wanting to have a bowel movement but not passing too much each time. In this case, you can go to the gastroenterology department for a check-up. If there are hemorrhoids, rectal mucosa prolapse, intussusception, or pelvic floor spasms, these may all cause these symptoms. A colonoscopy can be performed, and then the gastroenterologist can check for any abscesses around the anus or hemorrhoids to determine the specific condition and provide targeted treatment.

Slow intestinal movement or inability to function properly may lead to obstruction during bowel movements, affecting bowel movements and resulting in only a small amount of stool being passed. In addition, some intestinal muscles may not have enough strength, leading to less stool being passed, which is commonly seen in frail elderly people.
