Diverticulitis is a common condition that typically affects the sigmoid colon but sometimes can affect all parts of your colon. Approximately 50% of Americans at age 50 will have diverticulosis, meaning out-pouching of the colon. These can get infected or inflamed. This can cause pain, abdominal bloating, nausea, constipation, and is commonly called diverticulitis. This condition ranges from mild to severe and sometimes surgery is the best cure. Our surgeons can help you decide if surgery is right for you.
