4 Our Values: Caring about what we do Respecting and valuing each other General advice For a successful examination to be carried out, it is very important that the bowel is completely clean and you adhere to the following instructions. If the instructions are not followed correctly the examination may have to be repeated. Some investigations required you to fast for extended periods of time to ensure the bowel is completely clean. For people with diabetes, any procedure that causes you to miss a meal or change your usual meal plan will require special planning to safely manage your blood glucose. Some diabetes treatments can, if taken without food cause your blood glucose level to drop too low i.e. you can become hypoglycaemic. (Blood glucose below 4mmol/L) For this reason we recommend some alterations to some of your usual diabetes medication. 4 Caring with Pride: Our ultimate objective is to be trusted to deliver

5 Listening in order to improve Always doing what we can to be helpful For people treated with, try and avoid your blood glucose dropping too low when you are fasting. You may need to take regular amounts of sugary drinks instead of solid food at your usual mealtimes. Include one of the following sugary drinks. 200mls Lucozade 300mls Coca Cola (not diet ) 200mls clear apple juice What to do with your medication. For people who take injections it is recommended you reduce your doses the day of your bowel preparation and the day of the test. The chart on pages 8-10 will help you manage your diabetes treatment if taking when undergoing your bowel preparation or fasting period. For people on tablets the recommendation is you do not take any of your diabetes tablets the day before the test and on the morning of your test. You can restart your usual medication after the test is complete. If you are taking GLP-1 including Byetta (exenatide), Victoza (liraglutide) or Lyxumia (lixisenatide) by injection, these medications should not be taken on the day of your procedure and restarted once you start eating and drinking normally. safe, effective and sustainable healthcare within our communities 5

6 Our Values: Caring about what we do Respecting and valuing each other Monitoring your blood glucose levels If you monitor your blood glucose levels it is a good idea to check before each meal on the preparation day (day before the test) and before you arrive for your test and if at any time you have symptoms of hypoglycaemia (low blood glucose) or very high blood glucose. If you do not normally monitor your blood glucose levels at home, you do not need to do so for this period. Bring all your medication including, your blood glucose meter, test strips and hypo treatment with you on the day of the procedure. What is a hypo? A hypo is where your blood glucose level falls below the normal range usually less than 4mmol/L. This is usually associated with symptoms including feeling sweaty, shaky, feeling dizzy and heart racing. You need to treat your hypo immediately by taking rapid acting carbohydrate for example: 100mls Lucozade 150 mls - (mini can) coca cola or half a standard can 5-7 Dextrose tablets chewed 6 Caring with Pride: Our ultimate objective is to be trusted to deliver

7 Listening in order to improve Always doing what we can to be helpful Recheck your blood glucose level minutes later, if still below 4mmol/L repeat with more rapid acting carbohydrate as above. Once your blood glucose level has risen above 4mmol/L recheck hourly to ensure your blood glucose does not drop too low again. What to do after your procedure The nursing staff will inform you when it is safe to eat and drink after your procedure. Take your tablets / as advised from the flowchart when you are able to have your next meal. When you get home your blood glucose levels may vary for a short time, but this should quickly return to your usual level. These are general guidelines, if you have any concerns please call the diabetes team for further advice. safe, effective and sustainable healthcare within our communities 7
