Question: What are the treatments for What I need to know about Diverticular Disease ?
Answer: A doctor may prescribe antibiotics and recommend following a liquid diet. Most people get better with this treatment. Some people may need surgery and other treatments. - Surgery. Serious problems from diverticulitis are treated with surgery. Surgeons can clean the abdomen after infections and remove bleeding pouches and fistulas. - Colon resection. If you get diverticulitis many times, your doctor might suggest taking out the part of the colon with diverticula. The healthy sections can be joined together. With the diverticula gone, you may avoid other infections. - Emergency surgery. If you have severe problems, you may need emergency surgery to clear the infection and remove part of the colon. Later, a second surgery rejoins the healthy sections of the colon. The colon is separated for a brief time between surgeries, because rejoining the colon during the first surgery is not always safe. A temporary colostomy is needed between the two surgeries. A colostomy is an opening made on the abdomen where a plastic bag is connected to collect stool after food is digested. The surgeon makes the opening, called a stoma, and connects it to the end of the colon.
