The procedure is done using a long flexible tube, called a colonoscope. The colonoscope has a tiny camera and light on one end that is put in your rectum and moved into your colon. The camera sends images back to your provider for evaluation and can show inflamed tissue, polyps, ulcers, and other abnormal growths. Your provider may remove tissue or abnormal growths for further examination.  \nWhy do I need a colonoscopy?  \nYou may have a colonoscopy to:  \n• Look for problems in your colon such as: early signs of cancer, red or swollen (inflamed) tissue, open sores (ulcers) or bleeding.  \n• Examine the inside of your colon to: check for polyps and screen for colorectal cancer; check for the cause of blood in the stool or rectum, chronic diarrhea, iron deficiency anemia, or longterm, unexplained belly or rectal pain.  \n• Examine the inside of your colon after abnormal test results from a barium enema, blood in stool test, CT colonography scan, stool DNA test, or sigmoidoscopy.  \n• Treat colon problems such as inflammatory bowel disease (IBD) .  \n• Clean the lining of your colon with a water jet (irrigate) .  \n• Remove any liquid stool with a suction device.  \n• Inject air into your bowel to make it easier to see inside.  \n• Work inside your bowel with surgical tools.  \nWhat are the health benefits of having a colonoscopy?  \nOne of the major reasons to have a colonoscopy is to check for colon polyps or colon cancer. A colonoscopy can reveal pre-cancerous or cancerous polyps that may then be removed during the procedure or in a follow-up procedure. While not all polyps are cancerous some may become cancerous. Having a colonoscopy decreases your chance of having polyps that become cancerous over long periods of time.  \nWhat do colonoscopies detect?  \nA colonoscopy is used to screen for colorectal cancer. A screening means looking for cancer in people who don’t have any symptoms of the disease. A colonoscopy can help your provider look for and treat (if needed) problems in your colon such as colon polyps, tumors, ulcers, redness or swelling (inflammation), pouches (diverticula) along the colon wall, narrow areas (strictures) of the colon, and any objects that might be in the colon. *More information on colorectal cancer and other gastrointestinal procedures can be found under “Results and Colorectal Cancer”  \nWhat happens during a colonoscopy?  \n*More information found under “What to Expect on the Day of your Procedure”  \nYou may have your colonoscopy as an outpatient, meaning you go home the same day. Or your colonoscopy may be done as part of a hospital stay. The way your procedure is done varies depending on your condition and your healthcare provider’s practices. The colonoscopy follows this general process:  \n(a) Arrive and check-in approximately 45 minutes prior to your scheduled appointment time.  \n(b) You may be asked to remove any jewelry or other objects that might get in the way.  \n(c) You may be asked to remove your clothing and be given a gown to wear.  \n(d) An IV (intravenous) line with a sedative or pain medicine will be inserted in your arm or hand.  \n(e) You may be given oxygen to breathe in.  \n(f) Your heart rate, blood pressure, respiratory rate, and oxygen level will be monitored.  \n(g) You will be asked to lie on your left side with your knees pulled up towards your chest.  \n(h) A colonoscope will be greased, put into your anus, and moved into your rectum and colon. You may feel mild pain, pressure or cramping but the sedative should reduce your discomfort.  \n(i) Depending on the type of anesthesia or sedative, you may be completely asleep. If you areawake, you may be asked to take slow, deep breathes or change your position while the tube is being i","cbCairrTfhRAkX1n","https://ap.wps.com/l/cbCairrTfhRAkX1n","pdf",153287,12,"English","# What is a Colonoscopy?\n# Why do I need a colonoscopy?\n# What are the health benefits of having a colonoscopy?\n# What do colonoscopies detect?\n# What happens during a colonoscopy?\n# At what age should I have my first colonoscopy and how often do I need one?\n# Are there alternative procedures or tests to a colonoscopy?\n# What are the associated risks and complications with a colonoscopy?","[{\"question\":\"What is a colonoscopy and what does it look for?\",\"answer\":\"A colonoscopy uses a flexible tube with a camera to examine the inside of the colon and large intestine.
