Colonoscopy is a diagnostic and preventive procedure used to examine the inner lining of the large intestine (colon and rectum). Dr. Bhavesh Thakkar performs colonoscopy to investigate symptoms such as rectal bleeding, persistent abdominal pain, unexplained weight loss, chronic diarrhea, or constipation. It also plays a crucial role in screening for colon polyps and colorectal cancer. During the procedure, a flexible tube with a camera (colonoscope) is inserted through the rectum to visualize the colon. Polyps or abnormal growths can be removed, and tissue samples can be collected for biopsy—all in one session, ensuring timely and accurate treatment.
