Preparing for a colonoscopy

Of the members of the social group of five people I belong to, four have been diagnosed with inflammatory bowel disease, and at least four have undergone a diagnostic colonoscopy. This story goes an awful lot of people… I’m going to see the doctor yet again next week for another colonoscopy and a CT scan.The colonoscopy is performed by a doctor experienced in the procedure and lasts approximately 30-60 minutes. Medications will be given into your vein to make you feel relaxed and drowsy. You will be asked to lie on your left side on the examining table. During a colonoscopy, the doctor uses a colonoscope, a long, flexible, tubular instrument about 1/2-inch in diameter that transmits an image of the lining of the colon so the doctor can examine it for any abnormalities. The colonoscope is inserted through the rectum and advanced to the other end of the large intestine.


Your doctor places a thin, lighted tube through your anus and rectum up into the colon. Before the procedure, you get a sedative and pain medication to make you more comfortable. The colonoscopy tube has a small camera on it. It shows your doctor images of the inside of your colon as the tube moves through. The doctor can also take a small sample of tissue through the tube to examine later. Getting this type of sample is part of a test called a A doctor called a gastroenterologist, or GI doctor, usually does a colonoscopy. This type of doctor specializes in the digestive system. A surgeon may also do the procedure. Your team will also include a nurse and possibly an anesthesia specialist. (Source:biopsy. You will need to take a laxative or give yourself an enema at a certain time before the colonoscopy.

Your doctor's office will tell you what to use. The laxative is a pill or a powder you mix with water before drinking. A laxative speeds up the process of waste leaving your colon and it will make you have more bowel movements than usual. There is a small risk that the tube used for a colonoscopy might puncture the colon. This is rare, but you might need surgery to repair it if this happens.

Your lifetime risk (defined as life to 85 years old) is approximately 6% (male or female). Your risk is roughly doubled if one (1) first degree relative (parent, sibling or child) had colon cancer or polyps after age 50, and is higher if the cancer or polyps were diagnosed at a younger age or if more members of your family are affected. Certain inherited disorders, for example, polyposis syndromes and hereditary non-polyposis colorectal cancer, can increase your risk of developing colon cancer, but those are rare. Other important risk factors include obesity, cigarette smoking, inflammatory conditions in the colon such as Crohn’s, Colitis and Ulcerative Colitis, red meat consumption, and excessive alcohol consumption.

Your doctor is in the best position to discuss whether your personal or family history suggests one of those conditions.If one or more first degree relative (parent, sibling or child) has had a precancerous polyp or colon cancer, the general guideline is to begin colon cancer screening 10 years younger than the youngest age of the family member with colon cancer, or age 40, whichever is younger. There are additional guidelines for suspected or confirmed rare syndromes, and you should discuss these options with your doctor. (Source:gi.org)
