Colitis

Colitis is swelling (inflammation) of the large intestine (colon).

Most of the times, the cause of colitis is not known.

Causes of colitis include:

Symptoms

Symptoms can include:

Exams and Tests

The health care provider will perform a physical exam. You will also be asked questions about your symptoms, such as:

  • How long have you had the symptoms?
  • How severe is your pain?
  • How often do you have pain and how long does it last?
  • How often do you have diarrhea?
  • Have you been traveling?
  • Have you been taking antibiotics recently?

Your provider may recommend a flexible sigmoidoscopy or colonoscopy. During this test, a flexible tube is inserted through the rectum to examine the colon. You may have biopsies taken during this exam. Biopsies may show changes related to inflammation. This can help determine the cause of colitis.

Other studies that can identify colitis include:

Treatment

Your treatment will depend on the cause of the disease.

Outlook (Prognosis)

The outlook depends on the cause of the problem.

  • Crohn disease is a chronic condition which has no cure but can be controlled.
  • Ulcerative colitis can usually be controlled with medicines. If not controlled, it can be cured by surgically removing the colon.
  • Viral, bacterial and parasitic colitis can be cured with appropriate medicines.
  • Pseudomembranous colitis can usually be cured with appropriate antibiotics.

Possible Complications

Complications may include:

  • Bleeding with bowel movements
  • Perforation of the colon
  • Toxic megacolon
  • Sore (ulceration)

When to Contact a Medical Professional

Call your provider if you have symptoms such as:

  • Abdominal pain that does not get better
  • Blood in the stool or stools that look black
  • Diarrhea or vomiting that does not go away
  • Swollen abdomen
