Incontinent bowel movement refers to the feeling that the stool is not fresh after defecation, and that there is an urge to go to the toilet, but after going to the toilet, the stool cannot be solved. This feeling is the discomfort of defecation due to certain stimulation of the rectum, and the patient may have constipation or diarrhea, which can be accompanied by the usual feeling of incomplete defecation. When such a problem occurs, it is advisable for the patient to go to the gastroenterology department for colonoscopy and stool tests if possible. On the one hand, it can be due to some mental and emotional factors, such as fatigue, emotional excitement, as well as dietary and functional factors that can cause such feelings. In addition, some organic pathologies must be excluded, such as inflammatory bowel disease and chronic enteritis, colon tumors and colon polyps, etc. Older people with malnutrition and a decreased sense of control over bowel movements may also experience such symptoms. In any case, it is important to go to a specialist hospital and have the doctor perform the appropriate colonoscopy or stool tests to further clarify the diagnosis.
