Colonoscopy Procedure

COLONOColonoscopy is a procedure that uses a long, flexible, narrow tube with a light and tiny camera on one end, called a colonoscope or scope, to look inside the rectum and entire colon. Colonoscopy can show irritated and swollen tissue, ulcers, and polyps-extra pieces of tissue that grow on the lining of the intestine. A gastroenterologist – a doctor who specializes in digestive diseases-performs this procedure.

A colonoscopy is performed to help diagnose

  • Changes in bowel habits
  • Abdominal pain
  • Bleeding from the anus
  • Weight loss

A gastroenterologist also performs a colonoscopy as a screening test for colon cancer. Screening is testing for diseases when people have no symptoms. Screening may find diseases at an early stage, when a health care provider has a better chance of curing the disease.


Instruction: Patient should come empty stomach (overnight fasting) for the procedure.
