Surgery FAQs

The term “Bariatric” relates to the treatment of obesity and weight related disease. Hence, bariatric surgery is surgery for those suffering obesity and wanting to lose weight.

Weight loss surgery is indicated for those with a Body Mass Index (BMI) >40, or those with a BMI >35 and suffering from obesity related disease. This includes diabetes, sleep apnoea, high cholesterol, high blood pressure and osteoarthritis. If you think this is something you would like to consider, book an appointment with one of our experienced surgeons to see if we can find an option that is right for you.

Bariatric Surgery through Northern Bariatrics is a flat rate that includes our follow-up and our aftercare program. The out-of-pocket expense for each individual will depend on private health insurance and the level of rebate with your insurer. If you do not have private health insurance, there are self-funding options available. For a quote, contact our rooms today.

You will remain in hospital for an average of 1–3 nights following the procedure. After this, depending on your occupation, people can require up to 4 weeks off work. This is due to the recovery needed from the procedure, but more importantly, becoming accustomed to the dietary changes required following the procedure. You will be gradually upgraded from a liquid diet up to a full texture diet over a 6-week period, and this can take some getting used to.

Bariatric surgery is merely a tool for lifestyle change, which in effect should lead to weight loss. Our team will discuss with you the healthy eating habits and activity changes that will help you reach your goals.

Although this will make bariatric surgery a more cost-effective option, you do not need private health insurance to see one of our bariatric surgeons.

There is no specific timeframe recommended, as each individual will be different. If after a consultation with our surgeons you wish to pursue bariatric surgery, you will be seen by our metabolic team. The aim of this is to make sure any medical issues are optimised prior to surgery, and that you are educated on the changes you will be experiencing both physically and mentally. Once you have been signed off by the surgeon, metabolic team and anaesthetist, we will find a surgery date that works with you.

Diet and exercise weight loss programs can be effective for a small proportion of people. However, as stated by the National Institute for Health (NIH) in those suffering morbid obesity, it is unlikely that these conventional programs will lead to significant or sustained weight loss. This can lead to weight regain and feelings of failure, and a repetitive cycle of dieting. Surgery aims at resetting those homeostatic mechanisms that lead to weight regain, as well as helping with hunger and appetite. These things combined means that surgery is much more likely to lead to long term success.

Aftercare FAQs

The rate of weight loss varies between each person, however most will achieve the largest weight loss within 6-12months, and most will plateau at approximately 12 months.

Your surgeon and dietician will want to see you within 6 weeks following surgery. After this, you will have multiple appointments over the following 24 months to help you adjust to your new lifestyle and help keep you on track.

This can include becoming intoxicated more quickly, from smaller volumes and for longer periods, than prior to bariatric surgery. We do not recommend consumption of alcohol during the initial weight loss period. And after this, only small and occasional consumption.
