Bariatric Surgery

Bariatric surgery (weight loss surgery) is designed to treat severe obesity. Obese patients can achieve an accelerated weight loss through various bariatric surgery options; this is achieved by reducing the size of the stomach, for example using a gastric band or removing part of the stomach altogether.

What is bariatric surgery (weight loss surgery)?

There are many different bariatric surgery options available and we pride ourselves as having not only the widest range of options available, but experience and safety that is unmatched anywhere else in Australia. We offer a variety of bariatric surgery (weight loss operations) such as laparoscopic sleeve gastrectomy (removing a large portion of the stomach), laparoscopic gastric bypass (the stomach is bypassed and food enters a small gastric pouch then into the small bowel for digestion) and laparoscopic adjustable gastric banding (an adjustable band around the stomach to assist in controlling eating habits).

How does bariatric surgery work?

This surgery alters the anatomy and function of the oesophagus, stomach and small bowel to drastically reduce hunger and eating capacity. Once patients have had bariatric surgery they are able to more easily control their eating, lose weight and gain health. Following successful bariatric surgery most patients find that diseases such as diabetes, high blood pressure and sleep apnoea significantly improve or disappear altogether.

Revision Bariatric Surgery

For those patients that have already undergone bariatric surgery in the past, at Upper GI Surgery one of our services is bariatric revision surgery. Some patients may not have managed to achieve or maintain their weight-loss goals, and some may suffer side effects from operations that were not suited to them.

Why choose Upper GI Surgery for your bariatric surgery

Bariatric surgery has been conclusively shown to increase life expectancy and quality of life of patients suffering from morbid obesity. Obesity is a complex, lifelong disease that requires long-term treatment. Patients who have undergone a successful weight loss surgery require more than just an operation to get a good result.

The three most important determinants of a good outcome are safety, effectiveness, and follow-up.


There is no unit/hospital in Australia that has performed as many of the three common weight loss operations (laparoscopic gastric band, sleeve gastrectomy and gastric bypass) for as long as the surgeons at St George Hospital. Our safety data is continuously audited and has always been in the top 90% with regards to complications and readmissions. Dr Talbot has been performing gastric banding and gastric bypass surgery since 2003 and sleeve gastrectomy since 2004 and has performed over 2500 surgeries in this time. He performs over 50% of the Laparoscopic Gastric Bypasses performed in NSW and has treated over 200 patients who have unsuccessful results from previous weight loss surgery with other clinics.


While all weight loss surgery operations are on average ten times more likely to help patients lose weight than dieting there is no doubt that not all patients suit all operations. We are happy to offer treatments that are not ‘procedure specific’ but rather those that are focused on someone’s individual requirements. We offer the widest range of treatments including the more common band/sleeve/bypass options, gastric plication, experimental procedures, endoscopic procedures, and repair/revision of failed or complicated surgery.


Obesity is a chronic lifelong condition. The habits that reinforce someone’s weight problem take years to develop and also may take many years to fix. Patients who come back for follow up appointments lose more weight and suffer fewer complications than patients who don’t. We have assembled a large team whose job is to support patients before, during and after surgery. Medicare pays a subsidy towards meeting some of the costs of these staff, but the majority of payment for these staff comes from your surgery program fee.
