Our surgeons Dr Mark Gately & Dr Martin McLeod were specialty trained in General Surgery in the Hunter Region and had subspecialty training in dedicated bariatric centres in Australia and internationally. They are highly trained to perform a variety of weight loss surgery procedures.

What are the outcomes of weight loss surgery?

Studies show patients experience average weight losses of around 20-30% and 25-35% after undergoing a sleeve gastrectomy or Roux-en-Y gastric bypass, respectively. Read our article: The Outcomes of Weight Loss Surgery

Is weight loss surgery safe?

Weight loss surgery, known as bariatric surgery, is generally regarded as safe surgery, in appropriately selected patients. Risks are lower than the longer-term risk of dying from heart disease, diabetes and other consequences of carrying more weight than a person’s organs can tolerate.
