The causes of fecal incontinence in the anal region are primarily considered to be due to local organic lesions, or disturbances in nerve control, which can also lead to incontinence. If fecal incontinence is caused by either of these two reasons, it generally will not heal on its own. Severe diarrhea or acute intestinal infections can also cause fecal incontinence due to an increased frequency of bowel movements and acute inflammatory edema of the local intestinal mucosa. This can be alleviated by taking oral anti-inflammatory and anti-diarrheal medications. If the incontinence is caused by excessive relaxation of the anal sphincter, surgical treatment can be considered. If it is due to other neurogenic changes, active treatment of the primary disease is needed.
