Crohn’s disease and ulcerative colitis (UC) are the two main types of inflammatory bowel disease (IBD). Both cause chronic inflammation in the digestive tract, but they differ in location, depth, symptoms, and treatment. Knowing the differences between Crohn’s disease vs ulcerative colitis is essential for proper diagnosis, symptom management, and long-term care.
What Is Ulcerative Colitis?
Ulcerative colitis affects only the large intestine (colon) and rectum, causing continuous inflammation and ulcers in the colon lining.
Common symptoms of ulcerative colitis include:
- Persistent diarrhea with blood or pus
- Abdominal cramping and pain
- Urgent bowel movements and rectal bleeding
- Unexplained weight loss and fatigue
What Is Crohn’s Disease?
Crohn’s disease can affect any part of the digestive tract from the mouth to the anus, and often appears in patchy sections of inflammation. Unlike UC, Crohn’s can extend deeper into the intestinal wall.
Common symptoms of Crohn’s disease include:
- Abdominal pain and cramping
- Chronic diarrhea
- Fatigue, reduced appetite, weight loss
- Fever, mouth sores, blood in stool
Key Differences Between Crohn’s and Ulcerative Colitis
Here’s a quick side-by-side comparison of Crohn’s disease vs ulcerative colitis:
Causes and Risk Factors
- Genetics (family history of IBD)
- Abnormal immune system response
- Environmental triggers (diet, smoking, stress, infections)
Treatment Options
- Medications: Anti-inflammatories, biologics, immunosuppressants, antibiotics.
- Lifestyle changes: Trigger-food avoidance, stress management, hydration.
- Surgery:
- Crohn’s → may remove diseased segments, but recurrence is possible.
- UC → colectomy can cure UC, though alternative waste elimination is required.
