I want to have a bowel movement, but I can’t. This situation may be due to two reasons: First, there is indeed stool, but there is constipation. Due to the dryness of the stool stuck in the anal opening, you always want to poop, but can’t. You can apply opioid, oral lactulose, mannitol, hemp nuts and other drugs to assist in defecation. Usually pay attention to drink more water and supplement dietary fiber such as fruits and vegetables. Second, if there is no stool, or want to go to the toilet, mainly consider the symptoms of rectal irritation signs, that is, the presence of acute inflammation of the intestine, always want to go to the toilet, but also did not pull out much, and a while later want to go to the toilet.
