The physician will review the procedure with you and ask you to sign a standard consent form. This authorizes your doctor to perform the test. Please read this and be sure you understand it to your satisfaction. Be sure you have all your questions and concerns answered by the doctor before signing it.

Colonoscopy is usually performed on an outpatient basis. It is usually well tolerated and rarely causes much pain. There is often a feeling of pressure, bloating, or cramping at times during the procedure. Your doctor may give you medication through a vein to help you relax and better tolerate any discomfort from the procedure. You will be lying on your side or your back while the colonoscope is advanced slowly through the large intestine. As the colonoscope is slowly withdrawn, the lining is again carefully examined. The procedure usually takes 15 to 60 minutes. In some cases, passage of the colonoscope through the entire colon to its junction with the small intestine cannot be achieved. The physician will decide if the limited examination is sufficient or if other examinations are necessary.
