Obesity medications are indicated for adults with BMI ≥30 kg/m² (or ≥27 kg/m² with complications) and must be used in conjunction with lifestyle interventions to optimize effectiveness and health outcomes.
If you have obesity or are overweight with a related health issue, medications are a valid medical option, but they work best when paired with diet and exercise changes. You must meet specific BMI criteria (usually 30+, or 27+ with health issues). Crucially, if you start a medication and don't lose at least 5% of your body weight after 12 weeks at the maximum dose, you should stop it, as it likely won't work for you. However, for those who respond, these drugs can significantly improve health markers and quality of life.
In Australia, medications, in conjunction with lifestyle interventions, are indicated for weight management in adults (≥18 years of age) with obesity (body mass index ≥ 30 kg/m2) or those who are overweight (body mass index ≥ 27 kg/m2, or ≥ 25 kg/m2 for phentermine) with at least one weight-related complication.
