The Criteria for Weight Loss Surgery in Australia​



Weight loss surgery, also known as bariatric surgery, is a life-changing medical procedure that helps individuals who struggle with obesity achieve significant and sustainable weight loss. In Australia, weight loss surgery is becoming an increasingly popular option for those who have not been able to lose weight through traditional methods. However, the decision to undergo weight loss surgery is not one to be taken lightly. There are specific criteria that individuals must meet to be eligible for such a procedure. In this article, we will explore the criteria for weight loss surgery in Australia, helping you understand who may qualify and the steps involved in the process.

  1. Body Mass Index (BMI)

One of the primary criteria for weight loss surgery in Australia is a high Body Mass Index (BMI). BMI is a measure of body fat based on a person’s weight and height. Generally, candidates for weight loss surgery typically have a BMI of 35 or higher. However, for individuals with specific comorbidities like type 2 diabetes, sleep apnea, or high blood pressure, a BMI of 30 or higher may be considered. At our Bangkok Weight Loss Surgery Center, the minimum BMI is 32. 

  1. Previous Weight Loss Attempts

Before being approved for weight loss surgery, candidates are often required to demonstrate a history of unsuccessful attempts at losing weight through conventional methods such as diet and exercise. Medical professionals typically recommend that candidates have made multiple attempts to lose weight, with documentation of these efforts.

  1. Comorbidities

Weight loss surgery in Australia is often recommended for individuals with obesity-related health issues or comorbidities. Conditions such as type 2 diabetes, high blood pressure, sleep apnea, and joint problems are considered in the evaluation process. The presence of these conditions can increase a person’s likelihood of being approved for surgery.

       4. Age and General Health

Age is also a factor in the eligibility criteria. Generally, weight loss surgery candidates should be between 18 and 65 years old, although this can vary depending on individual circumstances. Additionally, candidates should be in good general health, with no uncontrolled medical conditions that could increase the surgical risks.

        5. Informed Consent

Candidates for weight loss surgery must give informed consent, indicating their understanding of the procedure’s potential risks, benefits, and long-term commitments. This process ensures that individuals are making an educated decision about their health.

        6. Support System

Having a supportive network of family and friends is vital for success after weight loss surgery. Candidates are encouraged to have a support system in place to assist them in making necessary lifestyle changes and coping with the physical and emotional challenges that come with post-surgery recovery.


Weight loss surgery is a powerful tool that can help individuals with obesity achieve significant and long-lasting weight loss. In Australia, specific criteria must be met to qualify for this life-changing procedure. These criteria include a high BMI, a history of unsuccessful weight loss attempts, comorbidities, a psychological evaluation, age, and general health, informed consent, and a support system.

Before considering weight loss surgery, it is essential to consult with a medical professional who can evaluate your specific circumstances and guide you through the process. Additionally, it’s crucial to be well-informed about the potential risks and benefits and the lifestyle changes required for post-surgery success. Weight loss surgery is a major decision, and understanding the criteria and requirements can help individuals make the best choice for their health and well-being.
