Lower GI Endoscopy, or colonoscopy, is a diagnostic procedure used to examine the lower gastrointestinal (GI) tract, including the colon and rectum. During the procedure, a flexible endoscope with a camera is inserted through the rectum to visualize the inner lining of the colon. This allows for the detection and diagnosis of abnormalities such as polyps, tumors, and inflammatory conditions. Lower GI Endoscopy is essential for diagnosing conditions like colorectal cancer, Crohn’s disease, and ulcerative colitis. Patients should opt for this procedure when experiencing symptoms such as persistent abdominal pain, changes in bowel habits, or rectal bleeding.
