Different symptoms that may lead to a colonoscopy to be suggested or performed include the following:
Before a colonoscopy procedure, the contents of the colon have to be emptied. This is usually done through a liquid-only diet for 24 hours as well as drinking a solution to help clear the bowels. If the bowel prep is not completed correctly, polyps and lesions can be missed and the entire procedure may have to be repeated.
Below is the most common bowel preparation for colonoscopies. Your Dignity Health Medical Group provider will discuss specifics with you prior to your scheduled procedure.
On the day before and up to the procedure, consume clear liquids only: broths, soft drinks, tea and coffee (with no milk or creamer), clear juices or Jell-O (but no red, blue, or purple coloring). You may also be asked to avoid nuts, seeds, hulls, skins, or other insoluble fiber for a day or more before beginning clear liquids.
This is an electrolyte-balanced solution consumed in large amounts (four liters, or about one gallon) the evening before a colonoscopy. You will need to drink eight ounces every tenminutes until the bowel’s output runs clear or the solution is completely consumed. In another approach, the dose is divided into three liters the night before and one liter the morning of the colonoscopy.
