GLP-1 medications are generally considered for adults with a BMI of 30 or above, or a BMI of 27 or above with at least one weight-related condition (such as type 2 diabetes, high blood pressure, or sleep apnoea). This tool calculates your BMI and gives you a plain-English note on where it sits relative to those general thresholds. Eligibility is always decided with a clinician.

Frequently asked questions
What BMI do you need to qualify for a GLP-1?
GLP-1 medications are generally considered for adults with a BMI of 30 or above, or a BMI of 27 or above with at least one weight-related condition such as type 2 diabetes or hypertension. Eligibility is always determined by a clinician after a full assessment.
Does BMI alone determine GLP-1 eligibility?
No. BMI is one factor. Clinicians also consider comorbidities, cardiovascular risk, previous weight-loss attempts, medication history, and contraindications. A BMI of 27–30 may still qualify with certain weight-related conditions. Eligibility is always an individual clinical decision.
