Can alcoholism cause loss of bowel control?

It depends...: Alcohol is a neurotoxin (poison for the nerves). After chronic use it can affect the small nerves first causing neuropathy in the hands and feet and eventually in other organs. Someone who is a heavy drinker who stops suddenly without being detoxed by a medical professional can have seizures during which there may be incontinence of urine and stool. It would be best that you consult an M.D.

Can in late stages: Chronic alcohol use can cause loss of bowel and bladder control in the later stages of the illness. Important to realize that most alcoholics do not look or feel very sick until they are almost dead.
