Colonoscopy preparation involves following specific instructions to cleanse the colon before the procedure. This preparation typically includes dietary modifications and consuming a laxative solution. Adequately preparing the bowel is a necessary step to ensure the colonoscopy is successful.
The Purpose of Colonoscopy Prep
The goal of colonoscopy prep is to thoroughly clean the colon. This cleansing allows the physician to clearly see the bowel lining during the procedure. A clean colon is important for detecting small growths, such as polyps, or other abnormalities. If the colon is not clear, these potentially concerning findings could be missed. The effectiveness of a colonoscopy relies heavily on the quality of this preparation.
Why the Full Volume is Crucial
The specific volume of laxative solution prescribed is carefully calculated to ensure complete bowel cleansing. These solutions contain osmotic laxatives, such as polyethylene glycol (PEG), which draw water from the body into the intestines. This increased fluid volume works to soften and flush out all solid waste from the colon. The large volume helps trigger muscle contractions, known as peristalsis, moving contents through and out of the digestive tract.
Consuming the entire prescribed amount is important for achieving the necessary level of cleanliness, resulting in clear, yellowish stool without solid particles. If the full volume is not consumed, residual stool or fluid can obscure the view of the colon lining. This can compromise the physician’s ability to identify polyps or other lesions.
Strategies for Completing the Prep
Successfully drinking the entire volume of colonoscopy prep can be made easier with various strategies:
- Chilling the solution can improve its taste, especially if you find it less palatable when warm.
- Drinking the solution through a straw may help bypass taste buds.
- Set small consumption goals, such as drinking a glass every 10 to 15 minutes.
- Add clear flavorings, like lemon-lime sports drinks or certain clear powdered drink mixes, but avoid red, blue, or purple dyes.
- Take short breaks if nausea occurs, and stay near a bathroom given the laxative effects.
- Adhere to the doctor’s specific instructions regarding timing and consumption.
What Happens If You Don’t Finish
Not completing the prescribed colonoscopy prep can lead to several complications. An incomplete prep results in residual fecal matter that can obstruct the view of the colon lining. This poor visibility makes it difficult for the physician to examine the area, increasing the risk of missing polyps or other abnormalities.
In such cases, the procedure may need to be rescheduled, requiring the patient to repeat the entire preparation process. This can lead to additional inconvenience, costs, and a delay in diagnosis or preventative care. If a patient is struggling to complete the prep, contacting their healthcare provider immediately is advised, rather than simply stopping.
