What is Ulcerative Colitis?
Ulcerative colitis is an inflammatory bowel disease (IBD) that causes long-lasting inflammation and ulcers (sores) in your digestive tract.
Ulcerative colitis affects the innermost lining of your large intestine (colon) and rectum.
Symptoms usually develop over time, rather than suddenly.
Ulcerative colitis can be debilitating and can sometimes lead to life-threatening complications.
While it has no known cure, treatment can greatly reduce signs and symptoms of the disease and even bring about long-term remission.
Symptoms
Ulcerative colitis symptoms can vary, depending on the severity of inflammation and where it occurs. Signs and symptoms may include:
- Diarrhea, often with blood or pus
- Abdominal pain and cramping
- Rectal pain
- Rectal bleeding — passing small amount of blood with stool
- Urgency to defecate
- Inability to defecate despite urgency
- Weight loss
- Fatigue
- Fever
- In children, failure to grow
When to see a doctor
See your doctor if you experience a persistent change in your bowel habits or if you have signs and symptoms such as:
- Abdominal pain
- Blood in your stool
- Ongoing diarrhea that doesn't respond to over-the-counter medications
- Diarrhea that awakens you from sleep
- An unexplained fever lasting more than a day or two
Causes
The exact cause of ulcerative colitis remains unknown. Previously, diet and stress were suspected, but now doctors know that these factors may aggravate but don't cause ulcerative colitis.
One possible cause is an immune system malfunction.
Complications
Possible complications of ulcerative colitis include:
- Severe bleeding
- A hole in the colon (perforated colon)
- Severe dehydration
- Liver disease (rare)
- Bone loss (osteoporosis)
- Inflammation of your skin, joints and eyes
- An increased risk of colon cancer
Heredity also seems to play a role in that ulcerative colitis is more common in people who have family members with the disease. However, most people with ulcerative colitis don't have this family history.
Diagnosis
Your doctor will likely diagnose ulcerative colitis after ruling out other possible causes for your signs and symptoms:
- Blood tests.
- Stool sample.
- Colonoscopy.
- Flexible sigmoidoscopy.
- X-ray.
- CT scan.
- Computerized tomography (CT).
