Eat healthily in preparation for your operation especially fruit and vegetables. On the day of your operation you will be given a carbohydrate drink to keep your body fuelled for surgery. After the operation you may have nutritional supplements in the form of drinks- please take them as they will help your body recover. Try to drink plenty of fluids and inform the nursing or medical staff if you feel sick as you may need anti-sickness medications or a review by a doctor. Eat little and often post operatively to try and minimise sickness whilst building up strength.
