In the days leading up to your surgery, you'll need to make travel arrangements for getting to and from the hospital and think about what to pack.
Make sure you give your family and friends plenty of notice about your operation so they can take time off work to be with you, if necessary.
Check your hospital's policy on visiting times and let your family and friends know.

At some hospitals, you'll be asked to attend a pre-operative assessment, which may be an appointment with a nurse or doctor, a telephone assessment, or an email assessment.
You'll be asked questions about your health, medical history, and home circumstances.
If the assessment involves a visit to the hospital, some tests may be carried out.
This is to check if you have any medical problems that might need to be treated before your operation, or if you'll need special care during or after the surgery.
The tests you have will depend on what operation and the kind of anaesthetic you're having.
These tests might include blood tests, urine tests and pregnancy test for women.
This assessment will usually happen one or more days before your operation.
Make sure you know the results of any previous tests, as well as all the medications, vitamins and herbal supplements you take.
You'll be given clear information on:
If your doctor has instructed you not to eat (fast) before the operation, it's important that you don't eat or drink anything – this includes light snacks, sweets and water.
You need an empty stomach during surgery so you don't vomit while you're under anaesthetic.
If you take insulin because of diabetes, you'll still need to avoid eating and drinking before surgery, but make sure your medical team is aware of your condition so appropriate precautions can be taken.
You'll need to remove all body piercings, make-up and nail polish before your operation.
This can help reduce unwanted bacteria being brought into the hospital. It also helps doctors to see your skin and nails to make sure your blood circulation is healthy.
Some hospitals may request that you have a bath or shower before coming in for your surgery, or have one once you arrive.
If you're staying in hospital, you may wish to pack:
You may want to check with your hospital about their policy on the use of mobile phones, MP3 players and laptops or tablets during your hospital stay.
Remember to bring your appointment card or admission letter with you, too.

Think about how you'll get to the hospital and back again. You won't be able to drive yourself home, so you should arrange transport or ask a friend or relative to help.
In some cases, the hospital may be able to arrange transport home for you.
Some hospitals charge for parking. You may be able to check whether you have to pay for parking at your chosen hospital by finding your hospital and selecting "facilities".
If you're unable to attend your hospital appointment or don't feel well enough to have your operation, let the hospital know as soon as possible. They'll be able to talk to you about rearranging the appointment.
