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.
