Colonoscopy pep talk - FAQs
Q: Do I really need to have a colonoscopy?
A:The need for a colonoscopy is real. Colon cancer is the second leading cause of cancer deaths in the U.S, yet it’s totally preventable. During a colonoscopy, a gastroenterologist can remove benign polyps that can grow into colon cancer later on. That's one of the main reasons for this procedure, and makes it worth enduring. A colonoscopy stops colon cancer from ever starting or nips it in the bud!
Q: Does a colonoscopy hurt?
A: The doctor gives you pain relievers and a sedative to bring you into a state called "conscious sedation." This is not like general anesthesia, where you’re unconscious, but a pleasant, sleepy, relaxed dreamlike state in which you don’t feel a thing.
Q: Will I be in a private room?
A: Colonoscopy is always done behind closed doors, in a private room, with no other patients around. Your privacy is a top concern.
Q: Will I be unconscious during the procedure?
A: Before the exam, your doctor administers pain relievers and a sedative through an intravenous (IV) line. The sedative brings you into a state called "conscious sedation." This is not like general anesthesia, where you’re unconscious, but a pleasant, sleepy, relaxed dreamlike state in which you don’t feel a thing.
Some people worry that while they’re under conscious sedation they’ll say or do embarrassing things. Rest assured that these medications don’t work like that. They make you sleepy, but not silly.
Q: How will I feel afterward?
A: After the procedure, you’ll be taken to one of our state-of-the-art recovery rooms where you’ll wake up. Most people feel OK after waking up. Some feel a bit woozy. You’ll be watched closely by one of our nurses and given fluids. You may have some gas, which could cause mild discomfort. Basically, you’ll get up and walk out. But because you may be woozy from the sedation, you’ll need someone to drive you home.
Q: What if the doctor finds something?
A: The doctor will remove polyps because they could eventually become cancerous. If your doctor sees a large polyp or tumor or anything else abnormal, a biopsy will be done. For the biopsy, a small piece of tissue is removed. Having a biopsy is painless, because the inner lining of the colon has no pain receptor nerves.
Q: How often do I need a colonoscopy?
A: Your doctor will suggest how often you need this exam, depending on your personal risk for colon cancer. Doctors usually recommended starting at age 50 and repeating it every 10 years. If you have an increased risk for colon cancer, or have had previous treatment for colon polyps or colorectal cancer, the test may be done at a younger age and more often. Find out from your doctor whether you should start before age 50.
Q: I’ve heard some things about virtual colonoscopy. How does it compare to conventional colonoscopy?
A: Researchers say virtual colonoscopy is less reliable than previously thought and not ready for widespread use. According to a study of 600 patients at nine major clinics, its accuracy varies considerably, depending on the training and methods of the doctors performing it. Moreover, should a virtual colonoscopy reveal polyps or other suspicious tissue you would have to make an appointment for a traditional colonoscopy and go through the preparation process all over again. The American College of Gastroenterology recommends that people get a conventional colonoscopy, calling it the “gold standard” of colon cancer screening.
