Colonoscopy
A colonoscopy is a procedure used to examine the inner lining of the large intestine (colon) and rectum using a thin, flexible tube with a camera.
This procedure helps doctors detect, diagnose, and sometimes treat problems in the colon, including inflammation, ulcers, bleeding, polyps, and early signs of colon cancer.
Colonoscopy is considered the gold standard test for evaluating the colon and plays a key role in preventing colorectal cancer by detecting and removing polyps early.
Why is a Colonoscopy Done?
Common reasons include:
• Persistent abdominal pain
• Chronic diarrhea or constipation
• Blood in stool or rectal bleeding
• Unexplained weight loss
• Suspected colon polyps
• Screening for colon cancer (especially after age 45)
• Follow-up of previous polyps or intestinal disease
• Evaluation of inflammatory bowel disease (Ulcerative Colitis, Crohn’s Disease)
It is one of the most effective ways to identify serious conditions at an early stage.
