A colonoscopy is a procedure that lets your health care provider see your large intestine (colon). This procedure is done using a long, flexible tube (a “scope”) that passes into your rectum and through your colon.
Good to know
During a colonoscopy you will lie on your left side during your procedure. If your health care provider finds abnormal tissue, he or she may take a small tissue sample (biopsy). The sample will be sent to the lab for testing. A biopsy is not painful.
If your health care provider finds a polyp (a finger-like growth) he or she will remove it through the scope (polypectomy). The polyp will be sent to the lab for testing. A polypectomy is not painful.
The procedure takes about 15 to 30 minutes.
Arrange to have someone drive you home after your procedure. You will not be able to drive after your procedure. You cannot take public transportation home alone.
