​A colonoscopy allows your doctor examine the lining of your large intestine (colon) for abnormalities by inserting a thin flexible tube into your anus and slowly advancing it into the rectum and colon. This instrument, called a colonoscope, has its own lens and light source and it allows your doctor to view images on a video monitor.  Tissue can be biopsied during a colonoscopy.  Intravenous sedation is usually given during this procedure to ensure a painless procedure.

A colonoscopy may be recommended as a screening test for colorectal cancer. Colorectal cancer is the third leading cause of cancer deaths in the United States. 

A colonoscopy  may  be recommended to
evaluate symptoms such as:​
  • abdominal pain
  • bleeding
  • chronic diarrhea
  • ​constipation

A colonoscopy  may  be recommended to
monitor conditions
such as:​

  • ulcerative colitis​
  • Crohn's disease
  • previous diagnosis of colon cancer

​Before having a colonoscopy is performed, the colon must be completely clean to ensure an accurate and comprehensive exam.  The day before the procedure, a special diet and cleansing solution/oral laxative is usually ordered.   Please ensure you follow the instructions carefully.
