There may be the following reasons why the elderly can’t hold back their bowel movements: 1. Organic lesions: suffering from acute and chronic inflammation of the intestines, inflammatory bowel disease, polyps in the colon or tumors in the colon, which can lead to an increase in the number of bowel movements, abdominal pain, diarrhea, etc. The elderly may not be able to hold back their bowel movements because they are too old. Excessive bowel movements and poor reflexes in the elderly who are getting older may make it too late to go to the toilet and have uncontrollable bowel movements. This kind of organic lesion suggests that we must go to the hospital by the doctor for stool test, or even enteroscopy to clarify the nature of the disease, and give symptomatic treatment. 2, functional lesions: such as ageing leads to degenerative changes in the muscles of the elderly, the rectal sphincter function decreases, so the anal contraction function also decreases, and when there is a bowel movement, it is impossible to be able to control the bowel movement properly. Fecal incontinence. Normal degenerative changes in the elderly can be recommended to the patient to lift the anus exercise, so the elderly often appear stool can not help or to go to the hospital in time for consultation, by the doctor according to the situation to clarify the diagnosis.
