About Colonoscopy Preparation

If you have Irritable Bowel Syndrome and are about to have colonoscopy preparation, you can learn how to do this for your investigation.

Preparing For Your Test

Colonoscopy prep does vary from one unit to another. There are some basics though that most people will need to know:

Colonoscopy Preparation Picture

1) Medications

Your Colonoscopist needs to know about your medications.

If you are diabetic or are taking blood thinning drugs such as Warfarin, Aspirin, Clopidogrel, Rivaroxaban and Dabigatran  you need to seek advice from the unit where you are having your test.

Also, if you are taking Iron medications these generally need to be stopped 7 to 10 days before the procedure.

Check with your local unit for their policy on this.

2) Health Issues

If you suffer from kidney disease, breathing issues or heart disease, your Colonoscopist needs to know about it.

If you have kidney disease, preparation can be risky so this needs to be given with caution and in consultation with the endoscopy unit you are going to.

Your Colonoscopy Preparation

So, this is what you should do:

3 Days Before Your Test

3 days before your colonoscopy, you should avoid high fiber foods, a list of which is below:

Wheat bran, All Bran, Weetabix, shredded wheat, oat bran, bran flakes, wheatflakes, muesli, ready brek, porridge, Wholewheat, high fiber white, soft grain or granary bread, oatbread, Wholemeal pasta, brown rice, Wholemeal or granary flour, wheatgerm, fruit and vegetables, all red meats, foods containing wholemeal flour, oatmeal, nuts, dried fruit etc, fruit cake, Ryvita, digestive or Hobnob biscuits, Jam or marmalade with pips, red jelly, seeds and skins, sweets and chocolates containing nuts and fruit, muesli bars, chunky vegetable, lentil or bean soup, nuts, quorn, fresh ground peppercorns and houmous.

A list of foods that are acceptable include:

Cornflakes, rice crispies, ricicles, sugar puffs, coco pops, white bread, white pasta and white rice, white flour, potatoes, chicken, turkey, fish, cheese and eggs, milk puddings, mousse, sponge cakes, Madeira cake, rich tea, marie or wafer biscuits, sugar, jelly (not red) jam, jelly marmalade, honey, syrup, lemon curd, clear or sieved soups, salt, pepper, vinegar, mustard, gelatine, salad cream and mayonnaise. 

Day Before Your Test

You need to avoid solid foods and only drink clear fluids.

This means avoiding milk in tea or coffee or at least keeping it to a minimum.

It is important to drink plenty of clear fluids and I must stress this is the secret to a good colonoscopy preparation.

As for the laxatives to clear the bowel, there are various preparations including Picolax, Klean Prep, Citramag and Moviprep.

These usually come as sachets and need to be taken depending on whether your colonoscopy is in the morning or afternoon.

Morning prep should usually be taken at 08.00 (1st sachet) and 16.00 (2nd sachet), afternoon procedures will need the prep at 16.00 and 08.00.

After this, only clear fluids should be taken until 3 hours before your test and then you should remain nil by mouth.
