Name of Leaflet: Preparation for your CT Colonography Examination – Diabetic Patient
Date Produced: August 2013
Review Date: August 2015*Do not take this medication until you have received your appointment details.* Preparation for your CT Colonography Appointment There are 2 parts to this information leaflet. Part 1 tells you about Gastrografin, the special liquid that you need to take before your examination. Part 2 tells you how to take it and the special diet instructions you need to follow. Please read both sections of the leaflet completely and follow the instructions in order to prepare your large bowel for the test. If you do not follow these special instructions fully, we may not be able to perform the test. PART 1 - Gastrografin What Is Gastrografin and why do I need to take it? Your Doctor has arranged for you to have a CT Colonography examination, which is a CT scan of the large bowel. In order to see the inside of your bowel clearly we ask you to drink a special liquid called Gastrografin. It makes the CT pictures of your bowel clearer. Gastrografin is a contrast medium (a dye) which contains iodine. Please contact the CT Scan Department if you are allergic to iodine or have difficulty swallowing liquids. Does Gastrografin have any side effects? All drugs may have some side effects. Most people who receive Gastrografin experience few side effects. Gastrografin does have some laxative effects and it may cause diarrhoea so it is advisable to stay close to a toilet. It is important to take note of any new symptoms you experience after starting the preparation. If you are concerned please telephone the number on your appointment letter to speak to a member of the CT Team. In some cases Gastrografin can also cause nausea and vomiting, skin rashes and very rarely anaphylactic/allergic reaction. Can I take any other medications along with Gastrografin? If you are taking iron tablets stop taking them 7 days before your scan. Preparation for your CT Colonography Examination – Diabetic Patient Page 2 of 10
If you are taking Interleukin-2 or have done so within the last several weeks, then please telephone the Radiology Department and let us know the last date you took this medicine. If you are taking beta-blockers, any hypersensitivity or allergic type reaction can be aggravated. If you are concerned you may be experiencing any allergic reactions please contact your GP or A&E Department for advice. Unless taking any of the medication mentioned above, you should continue to take your regular medicines as prescribed by your doctor unless you are told otherwise. Is there any situation when I should not take Gastrografin? If you are hypersensitive to iodine-containing contrast media (“x-ray dye”) or have hyperthyroidism (over active thyroid) then you should not take Gastrografin. Please contact the CT Scan Department for further instructions or advice. If you are pregnant or think you might be pregnant, please contact the CT Department on the telephone number on this leaflet. If you are having tests or taking thyrotrophic radioisotopes for thyroid disorders, Gastrografin may make any tests or treatment less effective for up to several weeks. Always tell your Doctor that you have had Gastrografin recently. Caution Keep all tablets and medicines out of reach of children. Never give any medicine prescribed for you to anyone else.

PART 2 –Taking Gastrografin and Dietary Instructions What you have to eat before the test will improve the performance of the bowel preparation and the diagnostic accuracy of the procedure. Do not start to take this medication until you receive your CT colonography appointment. If you are a diabetic, please telephone us on 01942 8222368 to tell us before starting any preparation. As a diabetic you are at an increased risk of having a ‘hypo’ (low blood sugar - symptoms include sweating, shakiness, blurred vision, light-headedness) when not eating for any length of time. To avoid this we recommend you follow the instructions as below and if able, please regularly check blood sugar. Please make sure you have additional glucose drinks/glucose tablets at home. If you are concerned about the preparation for your test please contact your GP. Examples of suitable glucose drinks include: lucozade, fizzy drinks, clear fruit juices (but not diet or non-sugar versions).

fizzy drinks, coffee and tea.
At 7:00pm drink half of the bottle of Gastrografin (50mls) – you can mix it with an equal

Preparation for your CT Colonography Examination – Diabetic Patient Page 5 of 10On the day of the CT Colonography
Do not eat any solid food. You may drink water or clear sugary drinks.
Do not take insulin/diabetic tablets
Closely monitor your blood sugar.
You can continue drinking plenty of fluids right up to the procedure. Make sure you have
glucose drinks regularly (i.e. 100 mls glucose drinks every 2hrs).
Bring your insulin/diabetic tablets and some food with you to the hospital, to have after the
procedure if needed.
You will be in the Radiology Department for approximately one to one and a half hours.
Please refer to the accompanying leaflet “Having a CT Colonography” for further information
about the procedure itself.
What to expect after the procedure
You will need to wait in the Department for approximately 20 minutes after your examination.
You can return to your normal eating and drinking pattern. We recommend that you
drink plenty of fluids for the following 2-3 days.
Although the carbon dioxide used to inflate your bowel is absorbed quite quickly following the
procedure some minor abdominal discomfort may remain for 1-2 hours. Returning to your
normal diet and moving around will help to ease any remaining discomfort.
However please seek urgent medical advice (your GP or Accident and Emergency out of
hours) if you experience any of the following symptoms over the next 4 days:
1. Severe abdominal pain
2. Increasingly painful abdominal discomfort
3. Sweating and nausea
4. Feeling generally unwell.
You may have been given an injection (Buscopan), used to relax the muscles in the bowel
wall during your examination. Blurring of your vision can be a side effect of this injection,
although, this side effect is short lived, usually 30 minutes. If you do experience blurring
please make sure your vision has returned to normal before driving.
Preparation for your CT Colonography Examination – Diabetic Patient Page 6 of 10Very rarely some people can develop blurred vision within 48 hours of this test as this injection can cause an underlying condition called glaucoma, if so you are advised to seek medical help. How to contact us If you have any questions, concerns or you need any further information, please contact the CT Scan Department on 01942 822368.

70% of people that smoke would like to quit. The Trust is a smoke free area and smoking is
prohibited in all buildings, grounds and car parks.
For patients wishing to quit smoking following their admission to hospital, or if patients simply
require support during their hospital stay, there is a designated specialist Stop Smoking Team
available.

also access specialist support. The Wigan Stop Smoking Service community team provides
support across the borough. You can call us on 01942 482539 or free on 0500 7867 669 to
