Examining the Large Intestine (Colon) and Rectum
A colonoscopy is a procedure that allows your gastroenterologist to examine the inside of your entire large intestine (colon) and rectum. It’s one of the most effective tools for detecting and preventing colorectal cancer, as well as for diagnosing various digestive conditions. A colonoscopy can identify issues early—often before symptoms appear—allowing for timely treatment and better health outcomes.
Colonoscopy
How a Colonoscopy Works
During the procedure, your doctor uses a thin, flexible tube with a small camera and light at the tip (a colonoscope). The colonoscope gently passes through the rectum and into the colon, sending high-definition images to a monitor for detailed examination. If polyps or abnormal tissue are found, they can often be removed during the same procedure. Biopsies may also be taken for further analysis.
What to Expect Before, During, and After
Before Your Procedure
Our team will provide detailed prep instructions, including how to clean out your colon the day before (often with a special liquid and clear liquid diet). Good preparation is essential for obtaining accurate results.
During Your Procedure
You’ll receive sedation so you can rest comfortably. Most patients feel no pain and don’t remember the procedure itself. It typically takes between 30 and 60 minutes.
After Your Procedure
You’ll relax in our recovery area until the sedation wears off. Some mild bloating or cramping is normal for a few hours. You’ll need a driver to take you home. Your doctor will review the findings with you, and the biopsy results will be shared once they are available.
