Colonoscopy is the procedure or test administered by inserting a long tube into the rectum to examine its condition. This test is usually conducted for eliminating the abnormalities in rectum and colon (large intestine).
During the testing process, a lengthy flexible tube is inserted into the rectum and a tiny powerful camera is kept on the other side. The doctor will view the camera for studying the condition of the colon. The tube is also used to remove certain polyps to conduct biopsy for eliminating cancer. Though it may sound very simple, the procedure of colonoscopy has some risks. Some patients are subjected to side effects and adverse reaction because of the given sedative while examining the colon. Bleeding can occur from the site where small tissue is removed. In rare cases, there may be small tear in the wall of the rectum causing injury.
Preparation is necessary for conducting colonoscopy test. The person should come empty after emptying the colon completely. Any residue or fecal matter will be removed using enema. Generally the doctor will ask you to take special diet a day before the process so that unwanted diet will not stay in the colon.
Drinking alcohol should be avoided before a day or two since it can get confused for blood. The person should not eat or drink anything after night and keep his stomach empty for getting ready for test.
Laxative is given in the form of pill or liquid to clean the colon and it is necessary to use that once or twice before the testing. For many persons, enema is given either on the night or just before the testing for cleaning the colon fully.
Based on the result, your doctor will initiate treatment for the findings on the intestine and rectum.
