IBS has few associated complications. IBS does not lead to rectal bleeding, colon cancer, or inflammatory bowel diseases including ulcerative colitis. Diarrhea and constipation may aggravate hemorrhoids in people who already have them. If a person eliminates too many foods from their diet, and the diet is too limited in nutrients that could cause health problems.
Because irritable bowel syndrome is a chronic (long-term) disease, symptoms usually return from time to time. This may be influenced by factors such as stress, diet, or other environmental causes. No known treatment cures IBS. Multiple factors may play a role in aggravating IBS, so it is difficult to predict what triggers may make IBS worse in a particular person. Establishing a good relationship with a health-care professional may help alleviate concerns over symptoms and allow rapid recognition of changing or worsening symptoms.
Avoiding triggers is the best way to prevent symptoms of IBS.
