How to Prepare for a Colonoscopy

Colonoscopy uses an instrument called colonoscope to internally examine the large intestine and rectum. The colonoscope has a small fiber optic camera attached to a flexible tube which is passed through the anus. Patients are normally sedated to avoid the pain. Pain killers may also be administered to reduce pain. The colonoscope will then be moved gently into the large bowel and sometimes into the lower part of small intestine. Sometimes, air is inserted through the scope to get better a view. You need to prepare yourself at least a week before you undergo colonoscopy.
