Colonoscopy Prep for Diabetic Patients

In order to have a thorough exam of the colon, it is necessary to have a good cleanout. This is the purpose of the laxatives you will be instructed to take before your procedure.

This cleansing preparation can lead to dehydration if you don't consume enough fluids. Diabetes and your medications can also contribute to dehydration, so it is doubly important that you consume enough clear liquids.

Follow prep instructions given to you for prep procedure.


Adjustment in Doses of Medicine One Day Prior to Procedure:

No change is necessary for Actos (Pioglitazone), Avandia (Rosiglitazone) or Precose (Acarbose). Take these medications as usual.

Do not take Glucophage (Medformin) or Avandamet. Resume medication when you resume your normal diet after the procedure.

Half normal dose: If you take Insulin or Diabeta (Micronase or Glyburide), Diabenase (Chlorpropamide), Amaryl (Glimepiride), Glucotrol (Glipizide), Starlix (Nateglinide) or Prandin (Repaglinide), take only a half dose of your medication. This half dose should be taken the day of preparation and the day of the procedure until you start eating normally again. Be sure to check your blood sugar 3 times per day on the day prior to your procedure.

General Instructions:

The clear liquid diet is much lower in calories than you usually consume, so you are allowed to drink clear juices, and we recommend that you do consume some juices to keep your energy up. Also, vary your clear liquids with broth and diet drinks. This will help you maintain normal electrolytes and keep you from feeling lightheaded.

The preparation works by flushing fluid through your colon. It is important to keep drinking so that there is fluid to use. This makes you feel better and allows a better cleanout.

Your blood sugar may run somewhat higher or lower at this time, but that is not cause for concern over the short term. If you experience low blood sugar you may drink clear juice or suck on hard candy. Do not forget to check your blood sugar!

We want you to feel comfortable about your preparation and are available to clarify issues specific to your case. Please call us with any questions at (706) 548-0058 and mention that you are going through preparation for a colonoscopy.
