A colonoscopy is an examination that allows doctors to investigate the colon and the inner lining of the intestine and is carried out using a flexible tube known as a colonoscope.
The colonoscopy usually takes around 20-30 minutes and during the test, a tissue sample, known as a biopsy, may be taken for analysis at the laboratory. In some cases, polyps, small projections from the wall of the intestine similar to warts may also be removed.
Colonoscopy is still considered the gold standard for assessing the colon because it allows diagnostics and biopsy to be performed at the same time. CT colonography (virtual colonoscopy) may be an alternative or adjunct in certain situations.

Before the colonoscope is inserted, painkillers and a sedative will be given, and a small device will be attached to your finger to monitor your pulse and breathing rate.
The procedure should not be painful, but it may be uncomfortable as the colonoscope moves around corners. However, any discomfort should wear off very quickly.
Sedatives can make you feel drowsy, so you may feel tired afterwards. It is advisable to avoid driving, operating heavy machinery or making important decisions for 24 hours after the procedure and you will need to ask a friend or relative to take you home and stay with you until you come round.
