Normal people suddenly incontinence, considering that may be caused by acute enteritis, nerve damage, anal sphincter injury, spinal cord tumors, intestinal tumors, etc., need to clarify the cause of the disease to take medication or surgical treatment.1, acute enteritis: if there is a dilute stool, the main consideration is that the acute enteritis caused by the stool can not be controlled followed by incontinence, you should go to the hospital to do the routine and enteroscopy and other tests to confirm the diagnosis, the application of antidiarrheal drugs, such as montelukast, Anti-inflammatory drugs such as norfloxacin and other combined treatment, while paying attention to dietary regulation, avoid eating spicy and fried and other stimulating foods, do not often stay up all night; 2, nerve damage: abnormalities in the brain nerves, resulting in fecal incontinence, should be to the professional cerebral medicine, neurology, neurology, neurophysiological response test and electroencephalography MRI examination, after diagnosis, can be used to olanzapine, cytrophosphocholine sodium and other nutritive nerve therapy, but also with Chinese acupuncture treatment. Anal sphincter injury: after anal fistula surgery, anal sphincter function will be affected and lead to fecal incontinence, patients need to pay attention to diet, avoid stimulating food, eat more fiber-rich food, keep normal stools, avoid diarrhea and constipation, and strengthen the anal sphincter muscle exercise in normal times, and surgery is needed for serious cases. 4. Spinal cord tumor: incontinence is a common sequela of spinal cord tumor surgery. Spinal cord tumor: incontinence is a common after-effect of spinal cord surgery, and the cauda equina nerve may be damaged, so surgery is recommended; 5. Intestinal tumor: if rectal cancer and colon cancer patients have large tumors, it can damage the sphincter muscle, so that anal sphincter loses its elasticity, and thus can not control the function of the anus, and the effect of general drug treatment is not obvious, so surgical treatment such as radical surgery of the local tumors may be considered to solve the problem.
