What Is A Colonoscopy?

A colonoscopy is a procedure performed to detect abnormalities in the large intestine (colon) and rectum. During your colonoscopy, a GI specialist will insert a long, flexible tube with a light and video camera attached into your rectum. This allows for a thorough inspection of the inside of your colon and rectum in real time. It also provides the opportunity for your gastroenterologist to take tissue samples or remove polyps if necessary.

Who Needs A Colonoscopy? Is There A Certain Age?

The American Cancer Society now recommends colon cancer screening for all adults at an average risk of colorectal cancer starting at age 45. Patients with a family history of colorectal cancer or other risk factors, may be advised to start regular screenings earlier.

How To Prep For A Colonoscopy?

Be sure to follow your GI doctor’s instructions carefully to properly prepare for your colonoscopy.

  • Maintain a clear liquid diet the day before your colonoscopy
  • Drink the cleansing solution / complete the bowel prep kit
  • Stay hydrated
  • Do NOT eat or drink anything the morning of your procedure
  • Inform your gastroenterologist of all your medications beforehand
