Crohn's colitis is a form of Crohn's disease that affects the colon. It leads to swelling and sores in the large intestine.
Unlike ulcerative colitis, which stays on the surface, Crohn's colitis can go deeper into the bowel wall.
People often ask about Crohn's vs. ulcerative colitis. This guide explains the key differences.
He starts by discussing your symptoms, past medical history, and any patterns in flare-ups or digestive issues.
These help check for inflammation, anemia, or infections that could point to Crohn’s disease or complications.
During colonoscopy, Dr. Chadha examines the colon lining and may collect tissue samples for confirmation.
He may recommend MRI or CT scans to assess inflammation beyond the colon or to detect complications like abscesses or fistulas.
This approach helps find answers fast and avoid delays.

No. They are distinct conditions with overlapping symptoms but different patterns of inflammation and tissue involvement.
Diagnosis involves a combination of medical history, blood and stool tests, colonoscopy with biopsy, and imaging studies such as MRI or CT enterography.

Many patients experience relief within weeks of starting therapy, but ongoing maintenance is crucial to sustain remission and prevent flare-ups.
Genetics increase susceptibility, but environmental factors and immune system behavior also play significant roles in disease development.
Both can cause fissures, but those from Crohn's tend to be deeper, more persistent and often associated with fistulas.
