Congratulations on a life-changing experience to be the best version of yourself, living life to the fullest! 

From the moment you make your first purchase with us - the welcoming, caring team at BN Healthy will be there to support you throughout your new, improved you. Once your Bariatric Surgery is finalised, there is still a long process ahead before actually undertaking your surgery.
Coming prepared before and following surgery will help ease your nerves.

Preparing for Bariatric Surgery

After finalising your Bariatric Surgery date, your team will give you specific recommendations for preparing for Weight Loss Surgery to make the surgery as safe as possible.

Pre-Op Plan:

You will often need to sustain a very low-calorie diet, consuming meal replacement shakes, soups, and some small meals for some time before your surgery. The recommendations for this stage may vary depending on your team.

Many of them are personalised, so it is crucial to follow the recommendations made for you, even if they are different from someone you know has been through the same process.

This "pre-op" phase is not aimed at weight loss directly.
The most important outcome of your pre-op phase is reducing the size of your liver to make sure the surgery can go ahead safely.
Your Bariatric Surgeon will tell you more about preparation for the actual procedure, including a preparation phase and a fast.


Being more active is an excellent complement to your preparation for surgery. Once you get the all-clear from your team, start gradually, and do something you enjoy by moving 20 to 30 minutes daily.

It will decrease the risk of complications during surgery, help with weight loss and get into a routine that will lead to long-term weight loss.
Exercise is also a great way to support your pre-surgery nerves and encourage a good night's rest. 


If you smoke, you will need to completely stop for at least three months before any surgery can go ahead, as smoking poses severe risks for surgery. Quitting smoking can be difficult; your Bariatric team can help with the resources and support you need.

Some surgeons will not operate on patients who use cigarettes. Depending on your specific needs and medical history, your team may have slightly different recommendations for you. Ensuring you take these recommendations is vital for your safety and feel more confident with the surgery.

Nutrition and Recovery:

Being "nutritionally fit" as you possibly can make all the difference to your recovery from surgery. Many Bariatric patients are deficient in Iron, B12 and Vitamin D before surgery. Catching these up after the procedure is made more difficult by the malabsorption the surgery causes.

Your team should run a complete set of blood tests to see where you are sitting in the pre-op stage. If you see any nutrients falling into the lower ends of the healthy range - this is the time to work on boosting.
Bariatric patients cannot absorb some nutrients efficiently due to the changes in the digestive system and reduced food intake.  


You'll need to take Bariatric specific vitamins and minerals every day for the rest of your life. Start building that into your routine with our range of BN Multivitamins

Medical Tests Before Bariatric Surgery

Weight Loss Surgery is a life-changing decision and carries certain risks.

Your surgeon will likely run a range of medical tests before your surgery to implement a safer process and decrease the chances of added complications that could compromise your well being and safety. Understanding the medical testing process can help put your mind at ease to help ensure that you are fully prepared for your surgery.

What medical tests may I need before Bariatric Surgery?

Barium swallow test

A barium swallow test provides your surgeon with a "road map" of your anatomy and digestive processes. It helps identify any potential complications that may hinder your surgery and recovery.

EKG (Electrocardiogram)

EKG (Electrocardiogram) measures the electrical activity of your heart. It can help rule out any underlying heart conditions that could complicate your surgery.

Exercise stress test

Exercise stress test involves walking on a treadmill or using an exercise bike and evaluating your cardiac function (heart functions) to determine how well your body manages physical activity. 


Ultrasound can identify any gallbladder inflammation or gallstones - if abnormalities in the gallbladder are found, your gallbladder may be removed during your surgery.

Thyroid test

A thyroid test and complete blood count is an all-inclusive overview of your overall health, helping to ensure you are ready for Bariatric Surgery.

Blood tests

A complete set of blood tests will assess your current state of health and act as a baseline for your nutrient levels. After Weight Loss Surgery, regular bloods will need to be checked for life. Any nutritional deficiencies are actioned before they have an opportunity to affect your newfound good health! 

Psychological Consultation

Weight Loss Surgery is not a one thought decision. The more you learn about bariatric surgery, the higher your chance of success is.
A Bariatric psychologist is an integral partner to support you from the very beginning and throughout your journey in pursuit of improving your quality of life and mental and physical health conditions.

Why is a Pre-Bariatric Surgery psychological consultation necessary?

Your surgeon and insurance require it.

Learn more about your challenges around eating, unique triggers, reasons for your habits and obstacles that prevent you from staying on track and provide you with a plan to help you post-surgical success. 

Discuss the surgery's psychological, behavioural and relational impacts on you.

Support you to prepare for surgery and beyond from the very beginning.

Pre-Surgery Diet

Once your Weight Loss Surgery is confirmed, your surgeon and dietitian will have you start a bariatric 'pre-op' diet to prepare for surgery. The diet before Bariatric Surgery is crucial to the safety of your surgery, and believe it or not, the focus of this stage is not on weight loss; it's all about reducing "fatty liver" to ensure the surgeon can perform your procedure safely.

Two weeks before surgery, you'll be on a Very Low Calorie (VLCD) preparation plan, including:

Meal replacements



High-protein, low-calorie foods

The goals of a Pre-Bariatric
 Surgery diet consist of:

  • Reducing the size of your liver to decrease the risk of complications
  • Increased protein intake to protect muscle tissue levels
  • Reduced overall inflammation in the body to improve surgical recovery

Support Group Meetings

Bariatric Surgery is a significant event at the beginning of your weight loss journey. Ongoing support needs to be a large part of the process to keep the weight off long term. We highly recommend attending at least two monthly support group meetings before your Bariatric / Weight Loss Surgery.

Support groups are designed to meet, interact and discuss problems, fears and achievements with others who can understand what you are going through and provide support. It can make a massive difference to the success of your weight loss journey, helping you know what to expect.

You will gain value from the information received and meet people who can share your journey and identify who genuinely appreciate your situation.

Final Steps to Getting Bariatric Surgery

Some of the final steps before Bariatric Surgery include:

Insurance approval:

Once you have completed all required medical tests, your Bariatric team will send the necessary documentation to your insurance company for pre-authorisation. The approval process will depend on your insurance company.

Schedule surgery:

Your Bariatric team will work with you to determine a surgery date and prepare you for the final steps.

Reassess what to expect:

Your Bariatric dietitian will educate you on your Post-Bariatric Surgery diet. Your Bariatric Surgeon will review what to expect at the hospital with you before surgery.
