There is a very small risk of injury to males during surgery which could cause impotence. Over 10 years in our support group, no men have experienced sexual difficulty following surgery. Women have become pregnant and have delivered healthy babies both by C-section and through vaginal delivery. Most people taper off steroids within weeks of surgery. However, if you have been on steroid therapy for a prolonged time, low dose maintenance may be needed.
Some people require medication or fiber therapy to decrease the number of stools per day.
No, the surgery plus removal of the mucus membranes in the anal area removes this problem. If there is no colon, you can't have colitis. Removing the colon also takes away the chance of colon cancer. However, there may be a small amount of rectal tissue that remains after surgery that should be checked periodically by your surgeon. Also foods can effect the number of movements each day.
