You are to undergo an examination of your large bowel. For this to be done properly the bowel needs to be prepared by adjusting your diet and taking a bowel preparation drug (strong laxative) the day before. The bowel preparation and appropriate instructions will have been sent to you separately. You may need to adjust you diabetes medication to prevent you having a low blood sugar and this leaflet will give you advice on how to do this.
Your blood sugar levels may not be as well controlled as you are used to during your bowel preparation so do not worry. The main aim is to keep you free of hypo’s (low blood sugar levels, less than 4 mmol/l). Your blood sugar levels should return to what you are used to a couple of days after the test.
