A colonoscopy is a medical procedure used to examine the inside of the colon (large intestine) and the rectum. This procedure involves the use of a colonoscope, which is a long, flexible tube with a camera and light source at the end. It is typically performed by a gastroenterologist or colorectal surgeon and is used for various diagnostic and, in some cases, therapeutic purposes.
Colonoscopy is considered a safe and effective procedure for diagnosing and, in some cases, treating conditions of the colon. However, like any medical procedure, it carries some risks, such as bleeding, infection, or complications related to anesthesia. Patients should carefully follow their healthcare provider's pre-procedure instructions, including dietary and cleansing requirements, and discuss any concerns or questions they may have about the procedure.
