The cause of ulcerative colitis is unknown, but may be a combination of genetic and environmental factors.

Ulcerative Colitis

If you are living with ulcerative colitis (UC), you’re not alone. Approximately half a million people in the United States are going through exactly what you are.

Ulcerative colitis is a chronic disease that affects the colon or large intestine. In people with UC, the innermost lining of the intestine, called the mucosa, becomes inflamed and develops tiny open sores. These sores bleed and produce pus and mucus. The inflammation causes the intestine to empty frequently, which results in bouts of bloody diarrhea and abdominal cramps. Some patients may experience fever.

Ulcerative colitis is a type of inflammatory bowel disease (IBD). Approximately 1 million Americans have IBD — half of whom have UC. Both men and women have an equal chance of being affected.

Ulcerative colitis usually develops between the ages of 15 and 30 and also between the ages of 50 and 70. However, the disease can occur at any age.
