Gastric Sleeve Surgery Near Me

Welcome to SIOS, home of the dedicated professionals in the field of obesity surgery in Australia.

When you find SIOS among the first results showing up while searching “gastric sleeve surgery near me” you are selecting an option for those who are interested in losing weight. This type of surgery is also known as laparoscopic gastric bypass surgery. This surgery is performed by making small incisions in the stomach and then dividing the stomach into two parts. The smaller part of the stomach is then removed, and the larger part is reattached to the small intestine. This surgery is usually performed under general anaesthesia.

The main aim of SIOS is to treat patients with obesity and help them achieve long-term weight loss. We offer a comprehensive and individualised approach to each of our patients, which includes pre-operative assessment, surgery, post-operative care and the follow-up program. We are a team of highly experienced and qualified surgeons, anaesthetists, nurses, and allied health professionals who are committed to providing the best possible care for our patients. We have successfully positioned ourselves as the number one institution showing up when you search “gastric sleeve surgery near me” providing second to none services at the highest standards known to date. A gastric sleeve surgery can help to improve or resolve a number of obesity-related health conditions, such as type 2 diabetes, high blood pressure, and sleep apnoea. All our patients often report an improved quality of life following surgery, due to increased mobility, increased energy levels and improved self-esteem.

If you are considering having gastric sleeve surgery, please contact us to book a consultation; our experts will be happy to assist you and walk you through the details to begin this process. We are entirely committed to offering our patients the best process so they can enjoy the benefits of being healthy and feeling well.

Understanding Bariatric Obesity Surgery

Every person and their body are different.  What works for one person, may not work for another.  There are many different surgeries available but finding the right one for you that is safe and healthy is our utmost priority.  Your health and lifestyle as well as food and weight concerns need to be carefully considered in the decision of which obesity surgery is best for you.


Depending on your individual weight and health, you may be a candidate for weight loss surgery. In order to determine whether this weight loss option is for you, take these first steps:

Medicare-Funded Sleep Studies

A good night’s sleep is important for good health and also for maintaining a healthy weight. Obesity may contribute to sleep problems such as sleep apnea, and sleep problems can also contribute to obesity. SIOS offers sleep studies, fully funded by Medicare.


Obesity surgery isn’t a quick fix, it requires a lifelong commitment to improving your health. Our better health journey program supports you with care, empathy and non-judgement from the SIOS team of allied health professionals.

For over 16 years, our weight loss surgery in Sydney has been there for all our patients.  We will be there for you, every step, through all your ups and the downs.
