Pharmacological treatment for obesity is indicated for adults with a BMI ≥30 kg/m², or ≥27 kg/m² with at least one comorbidity, when lifestyle changes are insufficient to achieve or maintain weight loss objectives.
If your BMI is 30 or higher, or 27 or higher with a health condition like diabetes or high blood pressure, and diet and exercise haven't worked, you qualify for prescription weight-loss medication. This is a standard medical indication, not a failure of willpower. Discuss this with your doctor to see if it's appropriate for you.
