A gastroenterologist diagnoses and treats conditions related to the digestive system, including the stomach and intestines. They perform colonoscopies to examine the lining of your large intestine for abnormalities, and the procedure involves inserting a thin, flexible tube with a camera into the rectum to view the colon. Proper preparation allows your doctor to see the colon wall without obstruction, which leads to a more effective examination. Here are some preparation tips for your colonoscopy:
Clean Out Your Intestines
Your colon must be empty before the procedure. Small amounts of stool or residue can obscure the view of the colon’s lining, sometimes causing the appointment to be rescheduled. Many doctors prescribe a strong laxative to flush waste from your system, and this is typically started the day before your appointment. The laxative is usually consumed over several hours and begins working quickly, resulting in frequent, sometimes urgent, trips to the bathroom. Staying at home and scheduling time for frequent restroom breaks will help you manage this process. Completing the full dosage, even if it is uncomfortable, will help avoid the need to repeat the procedure. If you experience severe bloating, nausea, or vomiting, notify your healthcare provider to discuss adjustments.
Follow a Clear Liquid Diet
Solid foods are off-limits the day before your procedure; this helps clear out any remaining food particles from your digestive tract. A clear liquid diet keeps you hydrated and allows your body to produce very little waste, making the preparation more effective and safer for the exam. Acceptable clear liquids include:
- Water
- Broth
- Clear juices like apple juice or white grape juice
- Plain tea or coffee without milk or creamers
- Sodas like ginger ale and lemon-lime varieties
Gelatin desserts and ice pops are often permitted, but you should avoid those with red, blue, or purple coloring. These dyes can stain the colon lining and appear as blood during the examination, complicating the results. If you accidentally eat solid food or drink a beverage with restricted colorings, contact your doctor right away. Transparency helps your medical team decide the next steps.
Adjust Medications
Some prescriptions and over-the-counter medications interfere with a colonoscopy, or they can increase the risk of complications such as bleeding. Review your current medication list with your doctor several weeks before your scheduled procedure. Blood thinners sometimes require temporary adjustment, and iron supplements can darken the stool, making it harder for the gastroenterologist to see the tissue lining clearly.
People with diabetes who use insulin or other medications may need to temporarily alter their dosage, as you will not be eating normal meals during the preparation. Taking the standard dose of these medicines without food could result in dangerously low blood sugar levels. Anti-inflammatory medications, such as ibuprofen and naproxen, may also need to be paused in advance. Follow your doctor’s instructions closely, and you should not stop or change doses without their guidance.
