Sleeve Gastrectomy

Gastric Sleeve Surgery

Also known as a sleeve gastrectomy, gastric sleeve surgery removes a large portion of the stomach, resulting in feeling fuller quicker

Roux en Y Gastric Bypass

Roux en Y Gastric Bypass

Backed by over 40 years of research, a Roux en Y gastric bypass is a keyhole procedure that creates a small stomach pouch that allows food to effectively bypass the small bowel, meaning fewer calories absorbed.

Omega Loop (Mini) Gastric Bypass

Omega Loop (Mini) Gastric Bypass

A mini gastric bypass creates a small stomach pouch and then joins the small intestine to the lower end of the stomach pouch, providing a shortcut for food meaning fewer calories are absorbed.

Lap Gastric Band Surgery

Lap Band Removal Surgery

Adjustable laparoscopic gastric banding was a previously popular weight loss procedure. Unfortunately it is now associated with poor outcomes. We specialise in gastric band removal and may consider an alternative procedure if appropriate.

“There are many options to manage obesity. Let us help find the right one for you.”

The Risks of Obesity – How Bariatric Surgery is the Answer

​​Did you know that 1 in 3 adult Australians is obese?

However, obesity is far more than simply numbers on scale; obesity is a leading risk factor for many serious medical conditions including type 2 diabetes, high blood pressure, heart disease, cancer, stroke, depression, infertility and over 200 other conditions. Research has shown that the longer you live with obesity, the greater the negative effect on your physical health and mental health and the shorter your life expectancy.

Unfortunately, yo-yo diets won’t work for many people, and this is when weight loss surgery (also known as obesity surgery) can help you achieve lasting results. Surgery works by influencing hunger and the way in which the body processes food/calories. It is expected that following weight loss surgery, a patient can eat everyday normal healthy food (in a smaller quantity), achieve their weight loss goals, enjoy a great quality of life and reduce their risk of serious medical conditions.
