Watch our Q&A session to help you make informed decisions.

We understand that deciding on weight loss treatment or surgery is a significant step.

Meet Mr Jason Winnett and team, learn about our process from the first appointment to post-surgery recovery, and get answers to common questions about bariatric surgery from our latest Q&A session.

Choosing the right path

We recognise that weight loss surgery is not a one-size-fits-all solution and every patient's journey is unique. We start with a thorough medical assessment to understand your specific needs and health conditions. Based on this assessment, we'll recommend the best treatment plan for you.
If surgery is determined to be the most appropriate option for you, we'll ensure you're well-informed about the procedure, risks, benefits, and costs. Some of the most popular surgeries we perform include Gastric Sleeve, Gastric Band/ LAP-BAND® and Orbera Balloon. Our goal is to keep you comfortable and informed throughout your journey with us, whether it involves surgical intervention or another form of assistance.
