Double GoLYTELY Colonoscopy Instructions

What is a Colonoscopy?

A colonoscopy is a test that lets the doctor view the inside of your lower digestive tract. It can help screen for colon cancers and can also help find the source of abdominal pain, bleeding or changes in bowel habits. Cancer of the colon and rectum is the second most common cause of cancer death in the United States. Screening for this cancer can prevent many of these cancer deaths.
