Decent Essays

Everyone should know that a lower GI is a very common and important exam used to diagnose many colon conditions. A lower GI examination, also know as a barium enema, is an x-ray examination of the large intestine. The large intestine, or large bowel, consists of the entire colon, including the appendix, rectum, and sigmoid colon.

You will be asked to turn to different positions, and the table may be tilted slightly to help the barium flow through your colon and to take x-rays from different directions. Sometimes a slightly different version of the test may be done. It is called a double contrast barium enema. If a double contrast study is being done, the barium will be drained out, and then air will be injected into your colon. As you can imagine with the air contrast study, the amount of cramping and pain increases, due to the expansion of the bowel with air. After all of the films are taken the enema tube is removed, and you are taken to the restroom to expel the remaining barium and air. One or two films may be taken afterwards, to check how much barium is remaining in your bowel. The entire test takes anywhere from thirty minutes to one hour. After the exam you may resume a regular diet, and be sure to drink plenty of liquids to replace those you have lost and to help flush the remaining barium out of your system.
