Colonoscopy Prep for Diabetics: Essential Instructions

Preparing for a colonoscopy while managing diabetes requires special attention to blood sugar levels, medication timing, and diet adjustments. Follow these essential steps to ensure a safe and smooth procedure.

Scheduling Your Colonoscopy

It is crucial to inform Dr. John Kurran’s office in advance that you have diabetes. Request an early morning appointment so that you can resume eating and taking your diabetes medication as close to your normal schedule as possible.

Diabetic Colonoscopy Prep: Managing Blood Sugar

Any procedure that requires fasting or a change in meal timing can affect blood sugar levels. Since your diet will be restricted to clear liquids the day before the procedure, careful planning is necessary to maintain safe glucose levels.

  • Monitor your blood sugar levels more frequently than usual during the preparation process.
  • Have a source of glucose available in case of low blood sugar, but ensure it complies with your prep instructions.
  • Avoid sugary drinks that could cause blood sugar spikes and crashes.

Consult Your Diabetes Care Provider

At least two weeks before your colonoscopy, contact your healthcare provider who manages your diabetes. Inform them about your upcoming procedure and ask about adjusting your medications during the prep period.

Key questions to ask your provider:

  • How should I modify my insulin or oral diabetes medication before and after the procedure?
  • What steps should I take if I experience low blood sugar during prep?
  • When should I resume my normal diabetes treatment after the colonoscopy?

Colonoscopy Prep and Low Blood Sugar: What to Do?

Since you will be consuming only clear liquids, there is a risk of hypoglycemia. Here’s how to stay safe:

  • If you feel dizzy, shaky, or weak, check your blood sugar immediately.
  • If needed, drink a small amount of clear liquid containing glucose (such as apple juice) after consulting your doctor.
  • Avoid beverages with artificial sweeteners, as they do not help raise blood sugar.

Clear Liquid Diet Guidelines for Diabetics

The day before your colonoscopy, you must follow a strict clear liquid diet. Approved options include:

  • Water
  • Clear broth (chicken, beef, or vegetable)
  • Unsweetened tea
  • Clear apple juice (in moderation, per doctor’s approval)
  • Electrolyte drinks (ensure they are low in sugar)

Avoid sugary juices, dairy products, and anything with pulp or artificial colorings.

Medication Adjustments and Final Preparations

Ensure you fully understand any changes your healthcare provider has recommended regarding your diabetes medication. Write down these instructions and follow them exactly on the day of your procedure.

Any questions regarding your diabetes medication should be directed to your healthcare provider.
