If fecal incontinence occurs, the first step is to identify the main cause of the fecal incontinence. If it is caused by relaxation of the anal sphincter and anal canal, then surgery can be performed to tighten this area, specifically through an anal tightening procedure, which can restore control over fecal incontinence. If the patient has other underlying diseases or is elderly and frail, accompanied by changes in the nervous system, the symptoms of fecal incontinence may be alleviated through medication or physical therapy, but complete recovery is unlikely. This is because the recovery of the nervous system requires the integrated regulation of other bodily organs and functions. If there are multiple underlying diseases or if the patient is elderly and frail, especially in the later stages of coma, recovery is difficult.
