If you’re going into hospital for an operation, it’s strongly advised that you stop smoking as soon as possible.
Quitting smoking before an operation will reduce your chances of complications and speed up your recovery after surgery. It will also make your stay at hospital more comfortable as smoking is not permitted on hospital grounds.
Try to quit smoking as soon as you can as this will give your body as much time as possible to repair itself before surgery.
The best way to quit smoking is with a combination of personalised support and stop smoking aids, like nicotine replacement.
