Always wanting to poop may be caused by acute enteritis, irritable bowel syndrome, intestinal tumors and other factors. 1. Acute enteritis: when the intestinal tract is attacked by bacteria and other pathogenic microorganisms and inflammation occurs, the inflammatory cells in the body will release some inflammatory mediators. These inflammatory mediators will not only cause an increase in vascular permeability, increasing the water content of intestinal contents, but also may directly stimulate the intestinal wall, causing increased intestinal peristalsis. Therefore, when acute enteritis occurs, the situation of always wanting to have a bowel movement may occur. 2. Irritable bowel syndrome: When irritable bowel occurs, gastrointestinal dynamics may change, and increased peristalsis occurs. Through peristalsis, the intestinal tract constantly pushes the intestinal contents toward the anus. After the intestinal contents reach the rectum, they may cause mechanical stimulation to the intestinal wall, thus inducing the bowel reflex. Therefore, when irritable bowel occurs, it may lead to always wanting to have a bowel movement. 3. Intestinal tumor: when there are tumor cells growing in the intestines, the tumor cells may cause damage to the intestinal wall tissue, which may cause the intestinal wall’s ability to perceive the stimulus to be disturbed, and thus the situation of always wanting to have a bowel movement may occur. There may be other reasons for always wanting to have a bowel movement, when there is always wanting to have a bowel movement, you should consult a doctor in time, and complete the examination of fecal bacteriological culture, fecal routine and colonoscopy under the doctor’s guidance, so as to clarify the cause of the disease and treat it positively.
