Getting ready for a colonoscopy
Before the test, you will be expected to prep your colon. The prep enables your doctor to have a clear view of your colon. Your doctor will give you instructions. The test can involve having a clear liquid diet, and having laxatives or enemas. Make sure you go over the instructions and understand them.
Your doctor will view the colon
With a colonoscopy, a very thin tube with a tiny camera is used to view the colon. The test takes about a half-hour. If a polyp is found, your doctor likely will remove it. Your doctor also may take a biopsy of tissue that will be sent to a lab to be checked for cancerous or pre-cancerous cells.
People usually are given medicine to make them relaxed or sleepy during the procedure. Colonoscopies are not painful.
