Preparing for Surgery

What can I do to improve my weight and health before having bariatric surgery?

There are things you can do now to improve your weight and health before you have surgery.

To have the best chance for a good outcome after bariatric surgery, you’ll need to make lifestyle changes and keep them for the rest of your life. Changes aren’t easy when you’re used to doing things a certain way for a long time. Part of making a change is practice and learning from the times that a change has gone well or hasn’t gone as well as you planned. The time before surgery is a good time to practice some lifestyle changes.

You may have already tried to make some of the following lifestyle changes to help you manage your health and weight. Keep those healthy habits. Other changes may be new habits for you, but you will need to make them after bariatric surgery. Click on the links below to learn how to build these healthy habits.

What other changes do I need to make after having bariatric surgery?

After bariatric surgery you will need to:

  • keep track of what you eat and how much you eat
  • take vitamin and mineral supplements
  • take care of your mental and emotional health
  • have regular blood tests and visits with your doctor
  • keep up the healthy habits you started before surgery

What can I expect while I wait for surgery?

Your clinic will give you information about your surgery and what to expect.

You will have medical tests to make sure that i​t is safe for you to have surgery. Tests may include a sleep test, blood tests, and tests to check how well your heart is working.

You will need to go to all appointments with your healthcare team at the clinic and keep working on lifestyle changes. Bariatric surgery is an elective surgery so if there is a higher priority surgery, your surgery may be delayed or cancelled.

What do I need to plan ahead for and arrange at home to help me recover from surgery?

Before surgery, make sure to plan and have things ready at home to help you rest and recover such as:

  • plan how you’re getting to and from hospital – you won’t be able to drive yourself home after the surgery
  • make sure you have someone to stay with you after surgery
  • arrange time off work and let your employer know if you won’t be able to return to all of your duties when you go back to work (such as lifting or standing for long periods of time)

What do I need to do in the days right before my surgery?

Your healthcare team will talk to you about what you need to do in the days before surgery, such as:

  • if you need to make any changes to the medicines you’re taking
  • what you can eat and drink
  • what to do if you need to clean out your bowels to prepare for surgery

On the day before your surgery, you will only be allowed to drink fluids. You won’t be able to eat or drink in the hours right before your surgery (fasting).​​​
