How common is bariatric surgery in Australia?

By 2025 more than 80 per cent of Australians will be overweight or obese according to the Monash Obesity and Diabetes Institute.

As a result of the obesity epidemic, the number of Australians undergoing bariatric surgery has increased from 500 in 1988 to 17,000 per year in recent decades.

What are the benefits of losing weight via surgery?

Research has consistently found that obesity has a negative impact on your health, life expectancy and can be detrimental to your quality of life (Medical Journal of Australia 2005). Weight loss surgery is recognised as the most effective method to lose a significant amount of weight and keep it off, and in turn reduce these negative impacts.

With regular follow-up, improved diet and exercise programs you may notice these benefits:

Your risk of premature death and obesity-related illness reduces dramatically.

  • Obesity surgery reduces and often resolves symptoms of obesity-related sleep apnoea, arthritis and diabetes.
  • You will have a reduced risk of heart attack, cardiovascular disease, heart failure or stroke.
  • Cancer risk reduces too, with obesity now a significant risk factor for many cancers
  • You may experience other health improvements. Infections heal more quickly and you’ll see the reduction in issues such as:
    • Nerve defects
    • Impotence
    • Blindness and eye disease
    • Kidney disease
    • Infertility, Irregular Bleeding or Polycystic Ovarian Syndrome
    • Reflux
    • High Cholesterol

You will enjoy a healthier, active and engaged lifestyle

  • You’ll be able to move about easier, play sports, enjoy hobbies and social activities with friends
  • Your body image, self-esteem and self-confidence will improve
  • You may experience decreased depression and stress

What is the cost?

The costs of the surgery can vary based on whether you have private health insurance, the types of procedure and the weight loss solution you select. At your initial consultation, you and your surgeon will have a thorough conversation about the costs applicable to you.

At times, options are available for self-funded patients. If this is your preference, please speak to the surgeon whether you are suitable.
