    • Preoperative diet

    Before your surgery, it is strongly recommended that you eat a protein-rich diet.

    You received a document about your preoperative diet at your pre-admission visit. This diet will improve your nutritional status 14 days before your operation and reduce the size of your liver. This makes the surgeon’s work easier and is associated with reduced complications after the surgery. 

    People with diabetes taking hypoglycemic medication or insulin should contact their treating physician or endocrinologist to modify their dose. Because of the low amount of carbohydrates in this diet, you need to monitor your blood sugar levels to prevent hypoglycemia.
