You operation will be carefully planned.
Your surgeon and anaesthetist are responsible for your well-being during and after your surgery. They must be sure that you are fit enough to undergo the operation. This means you may have to attend a hospital appointment before your operation to have some tests. This is known as a pre-assessment clinic.
If you’ve been having problems with eating and have lost weight, you may be given extra help and support with your diet. This is to help prepare you for the operation.
If you smoke, try to give up or cut down before your operation. This will help reduce your risk of chest problems such as a chest infection. It will also help your wound to heal after the operation. Your GP can give you advice. You may also find it helpful to read our section about giving up smoking.
