When should I get a colonoscopy?

Colonoscopy is indicated for patients having symptoms concerning for colorectal cancer or inflammatory bowel disease. Screening colonoscopy is indicated for average risk patients at age 50. Newer guidelines recommend screening start at age 45 for African Americans. If a family member has had colorectal cancer or adenomatous polyps before the age of 60, it is recommended you start screening 10 years before their age at diagnosis.

Am I sedated for my colonoscopy?

IV Sedation is commonly used for procedures such as colonoscopy and endoscopy. With Intravenous Sedation, sedative drugs are injected into a vein in your arm or hand. The drugs will make you drowsy and relaxed. Most people fall asleep and forget what happened during the procedure but the aim is to put you at ease during the procedure, not to make you unconscious.

Can I go to work the same day I have my colonoscopy? What about the next day?

It is recommended that you take the day off work on the day of your procedure. Some patients who work evenings will also need to take off work the day before the procedure to do the bowel preparation.

Does someone have to be with me for my colonoscopy?

You will need a responsible adult to pick you up upon discharge from the hospital. You are not allowed to drive for 24 hours after your procedure. You are not allowed to take public transport, unless accompanied by an adult for 24 hours after your procedure. You should not make any important decisions, sign legal documents, operate machinery or drink alcohol for 24 hours following the procedure.

Will I have to have clearence from my PCP for colonoscopy or surgery?
