Ulcerative Colitis

About Ulcerative Colitis

The exact cause of ulcerative colitis is unknown, but it is thought to result from your immune system attacking your large intestine and rectum.

Types of Ulcerative Colitis:

Ulcerative colitis is classified by the extent of the inflammation

• Ulcerative proctitis: Inflammation is confined to the rectum
• Proctosigmoiditis: Both the rectum and lower large intestine (also known as the sigmoid) are inflamed
• Left-sided colitis: The rectum and the left side of the large intestine are inflamed
• Pancolitis: The entire large intestine is inflamed

Symptoms of Ulcerative Colitis

Symptoms of ulcerative colitis can vary depending on which parts of the large intestine and rectum are inflamed. Even if your condition goes into remission, your symptoms may later “flare up” or reoccur.

Symptoms of ulcerative colitis may include:

• Abdominal pain
• Blood in stool
• Diarrhea
• Fatigue
• Anemia
• Weight loss

Risk Factors for Ulcerative Colitis

While experts don’t know what causes ulcerative colitis, the onset of ulcerative colitis is thought to be influenced by a combination of genetics, immune activity, and the environment.

Risk factors for ulcerative colitis may include:

• Age: Symptoms of ulcerative colitis typically first appear between the ages of 15 and 35 (though children and older patients may also develop this disease)
• Family history: Having a family member with inflammatory bowel disease increases your risk of developing the disease.

Diagnosing Ulcerative Colitis

No single test is definitive for making a diagnosis of ulcerative colitis. Several tests, including those listed below, can help provide the information your physician needs to make a diagnosis.

• Colonoscopy: This test looks at the entire colon and into the end of the small bowel (called the ileum). A flexible tube with a light and camera is inserted into the rectum and advanced into the colon and allows the physician to see the lining of the bowel. Signs of colitis include redness, swelling, ulcers and bleeding. Samples of the bowel (called biopsies) can also be obtained during this test for further analysis.
• Biopsy: Often obtained during colonoscopy, these samples allow for the tissue of the colon to be examined under a microscope to look for changes that suggest ulcerative colitis.
• Stool tests: Stool tests can include multiple pieces of information. They can be used to assess for inflammation in the stool (for example, a calprotectin test), to assess for infections (for example, C. difficile infection), or to evaluate for other causes of diarrhea.
• Blood tests: No blood tests can diagnose or definitively rule out ulcerative colitis. But some blood tests can be helpful to monitor the disease, monitor medications used to treat the disease, and evaluate for complications related to the disease.
