Yes, you will need a referral from your GP.

There are several different types of weight loss surgery. The two most common are gastric sleeve and gastric bypass, and each has its own advantages and disadvantages. Dr Peter Hamer and his team can help determine which surgery is best for your individual needs.

A few days.

One week is recommended, up to two. No heavy lifting for 6 weeks.

Sleeve gastrectomy is the most commonly performed weight loss operation in Australia and will generally be the first choice for most patients.

Gastric bypass is the most established weight loss operation world wide, with the best track record.  

Single anastomosis gastric bypass is a variation on traditional bypass that may be slightly safer.

Metabolic surgery is another name for weight loss surgery. The operations are the same as weight loss surgery, but some people prefer the name ‘metabolic surgery‘ as it emphasises the health benefits of sleeve gastrectomy or bypass rather than just the weight loss you will achieve. This may be important for you particularly if you have diabetes, obstructive sleep apnoea, high blood pressure or high cholesterol. For example, some people with type II diabetes who have metabolic surgery find that they can come off their medications, incredibly this often occurs within a few days of their operation before they have even begun to lose weight!

In general, bariatric surgery could be an option for you if your BMI is over 30.

Aftercare FAQs

Weight loss occurs over a 12 – 18 month period of time, but the most is lost over the first 6 months.

Gastric sleeve surgery is part of a holistic health program – and getting back to exercising will help you achieve your health goals! It is safe to walk as soon as you feel up to it. We usually recommend waiting about a month before going back to the gym or similar activities.

Hair can thin after weight loss surgery but doesn’t always occur.  Following the recommended diet after surgery (high in protein) can minimise this.

After weight loss surgery your body needs extra vitamins and minerals because you are only able to eat small amounts of food. This means your body may absorb less vitamins and minerals. For this reason, it is recommended that you take vitamin and mineral supplements every day as well as eating a healthy diet. Our dietitian will advise you on suitable vitamin supplements to suit you.
