Ulcerative colitis is a chronic disease that inflames the lining of the large intestine – the colon and rectum. People with ulcerative colitis have tiny ulcers and small abscesses in their colon and rectum that flare up periodically and cause bloody stools and diarrhea.
Ulcerative colitis usually affects people from 15 to 30 years of age. It can be inherited and is most common in the United States and northern Europe and people of Jewish descent.
Ulcerative colitis is characterized by alternating periods of flare-ups and remission, when the symptoms of the disease disappear. The periods of remission can last from weeks to years. Inflammation usually begins in the rectum and then spreads to other segments of the colon. How much of the colon is affected varies from person to person. If it is limited to the rectum, the disease may be called ulcerative proctitis. Ulcerative colitis, unlike Crohn's disease, does not affect the esophagus, stomach, or small intestine.
Symptoms of ulcerative colitis may include:
In addition, ulcerative colitis may be associated with weight loss, skin disorders, joint pain or soreness, eye problems, anemia (a deficiency in red blood cells), blood clots, and an increased risk for colon cancer.
The cause of ulcerative colitis remains unknown, but it is likely caused by an abnormal response of the immune system. Food or bacteria in the intestines, or even the lining of the bowel may cause the uncontrolled inflammation associated with ulcerative colitis.
Treatment for ulcerative colitis can include drug therapy, changes in diet, and/or surgery. Though treatments cannot cure ulcerative colitis, they can help most people lead normal lives. It is important for you to seek treatment for ulcerative colitis as soon as you start having symptoms. If you have severe diarrhea and bleeding, hospitalization may be necessary to prevent or treat dehydration, reduce your symptoms, and ensure that you receive proper nutrition.
