How do you diagnose and treat crohn's disease because i think i have it?

First see a doctor: Crohn's disease can be diagnosed with a combination of lab testing including xrays (enterography, ct scan) endoscopic biopsies and new serological markers (ibd panel). Newer modalities such as capsule endoscopy where you swallow a small pill-size camera that examines your intestines can help diagnose more subtle cases. The treatment is based on medications that suppress intestinal inflammation.

Colonoscopy : The gold standard for diagnosing crohn's if the colon or ileum is colonoscopy. Special ct and mre can help to see if the rest of the small bowel is involved.
