Normal people suddenly defecate incontinence

In normal people, sudden fecal incontinence is first considered to be caused by trauma to the anorectal ring, which causes the sphincter to lose its function. Examples include stab wounds, cuts, burns, frostbite, and lacerations.(mainly perineal tears during childbirth). In addition, neurological disorders such as brain trauma, brain tumors, brain infarction, spinal cord tumors, spinal tuberculosis, cauda equina nerve injuries, etc. can cause fecal incontinence. Finally, anal incontinence caused by anal and rectal diseases. For example, rectal tumors of the anal canal (such as rectal cancer, anal canal cancer), Crohn's disease and other invasion of the anal rectum, and accumulated to the anal sphincter; or ulcerative colitis, long-term diarrhea caused by anal inflammation; or rectal prolapse caused by anal relaxation, so that anal atresia incomplete, can cause fecal incontinence.
