Fasting for your operation is essential for safe anaesthesia
Stop drinking 2 hours before
Clear fluids (e.g. water, apple juice, or other fluid that you can read the newspaper through) may be consumed up to 2 hours before your operation.
General food and drinks
Stop drinking and eating 6 hours before
You need to fast from all food and milk drinks (including coffee) for 6 hours prior to your operation. This ensures that your stomach is empty and will reduce the risk of aspirating contents of your stomach into your lungs.
