How might collagenous colitis be treated?

Treatment for collagenous colitis varies depending on the symptoms and severity in each affected individual. In some cases the condition may resolve on its own (spontaneous remission), although most people continue to have ongoing or occasional diarrhea.[1]

Dietary changes are usually tried first to alleviate symptoms. These changes may include a reduced-fat diet, eliminating foods that contain caffeine and lactose, and avoiding over-the-counter pain relievers such as ibuprofen or aspirin. If these changes alone are not enough, medications can be used to help control symptoms.[1] However, the response rate to various types of medication reportedly varies.[2] Prescription anti-inflammatory medications such as mesalamine and sulfasalazine may help reduce swelling. Steroids including budesonide and prednisone can be used reduce inflammation, but they are usually only used to control sudden attacks of diarrhea. Long-term use of steroids is typically avoided because of unwanted side effects. Anti-diarrheal medications such as bismuth subsalicylate, diphenoxylate with atropine, and loperamide can offer short-term relief. Immunosuppressive agents such as azathioprine help to reduce inflammation but are rarely needed. In extreme cases where the condition does not respond to medications, surgery to remove all or part of the colon may be necessary. However, surgery is rarely recommended.[1]
