Understanding Your BMI Result

BMI (Body Mass Index) is one of several factors surgeons consider when assessing weight loss surgery candidacy. It's calculated using your height and weight.

General guidelines in Australia:

BMI 40+ typically meets criteria for surgery
BMI 35-39.9 may qualify with obesity-related health conditions (diabetes, sleep apnea, etc.)
BMI 30-34.9 may be considered in specific cases with multiple co-morbidities

⚠️ Important: BMI is just one factor. Your individual eligibility depends on medical history, health conditions, previous weight loss attempts, mental health assessment, and many other factors that only a qualified surgeon can evaluate.
