In a colonoscopy, the doctor inserts a tube that has a camera on the end of it into the rectum. The tube is threaded through the lower colon while the doctor looks with the camera to see if there are any polyps or other abnormalities. If a polyp is found, a sample is taken of the polyp or the polyp is removed in its entirety and examined under the microscope for evidence of cancer. This is why it is so important to have a proper colonoscopy preparation. Good preparation means that the entire colon is visible and no polyps are missed due to retained stool.

You will meet with the doctor before the colonoscopy to discuss the colonoscopy preparation as well as the particulars of how you’ll get home after the colonoscopy. You’ll need a ride because most doctors use sedation for the colonoscopy so you’ll be completely relaxed. In addition, you’ll want to have the doctor understand what medications you’re on and this includes herbal remedies. The doctor will tell you which medications you can take with a small sip of water the day of the procedure and which medications you can skip. Tell your doctor what allergies you have to medications or to latex.

Liquid Diet

The colonoscopy preparation ensures that your bowels are completely empty at the time of the procedure. This allows the camera to see the lining of the colon during its entire length. The preparation is vital to a successful colonoscopy. The first step is taking a liquid diet to begin to clean out the colon. The liquid diet can last anywhere from one to three days before the procedure.

In a completely liquid diet, you drink only clear liquids. This means not drinking milk, cream in your coffee or ice cream. The liquid diet involves drinking fat-free bouillon, either chicken, beef or vegetable. This is broth you can buy in cubes and mix with hot water. You can drink it with strained fruit juices, water, coffee with sugar or nothing only, tea with sugar or nothing only, or diet sodas. Jell-O or popsicles can be eaten in any color except for red and blue.

In a colonoscopy preparation, the dye colors red, blue or purple can mimic blood in the colon and can fool the colonoscopist into thinking there is bleeding in the colon or upper digestive tract. Use orange, yellow or green Jell-O or popsicles instead.

An additional measure in colonoscopy preparation involves the use of Golytely® or Fleets Phospho-Soda®. These are liquid medications that induce diarrhea and allows the entire intestinal tract to be flushed out and cleaned. These medications are often difficult to drink because there is a lot of fluid to drink and the drink is tasteless or slightly salty in taste. Many people struggle with taking these medications but they can be important to making sure there is no particulate matter left in the colon. You often take the medications the night or day before the colonoscopy procedure. These aspects of colonoscopy preparation are not used by all surgeons or colonoscopists.
