BMI ≥30A common adult obesity threshold
Wegovy and Mounjaro assessment
GLP-1 eligibility and BMI requirements
BMI is an important starting point, but it is not the prescribing decision. The doctor also reviews weight-related conditions, previous attempts, current medicines, pregnancy plans, contraindications, goals and whether monitoring can be provided safely.
BMI ≥27May qualify with a relevant weight-related condition
Doctor decisionEligibility is individual and never automatic
What the doctor reviews
Expect questions about blood pressure, cholesterol, sleep apnoea, diabetes, cardiovascular disease, pancreatitis or gallbladder history, digestive symptoms, medicines, allergies, pregnancy and prior GLP-1 treatment.
BMI is a screening tool—not a complete diagnosis
BMI does not describe body composition, frailty, eating disorders or every individual risk. Measurements should be accurate, and the doctor may recommend an examination or tests before treatment.
When an online pathway may not be enough
Complex symptoms, uncertain diagnosis, severe side effects, pregnancy, suspected acute illness or a need for physical examination may require in-person care. Prescribing is never guaranteed by a calculator result.

Safety first
Give the doctor complete and accurate information
The pre-check is screening only. Do not conceal medical history, medicines, previous injections, pregnancy plans or change measurements to qualify; inaccurate information can make treatment unsafe.

Common questions
GLP-1 eligibility and BMI requirements: questions
What BMI is usually considered?
For adult weight-management pathways, authorised criteria commonly include BMI 30 or above, or BMI 27 or above with at least one relevant weight-related condition. Individual assessment still applies.
Which weight-related conditions may be relevant?
Examples in authorised criteria include dysglycaemia or type 2 diabetes, high blood pressure, abnormal blood lipids, obstructive sleep apnoea and cardiovascular disease.
Can I qualify below these BMI ranges?
The doctor can discuss alternatives, but a medicine should not be prescribed outside an appropriate clinical pathway merely because it is requested.
Does diabetes change the decision?
Yes. Diagnosis, glucose control, diabetes medicines and the risk of low blood sugar require specific review.
Is BMI enough to decide treatment?
No. BMI is a screening measure. The doctor also reviews medical history, current medicines, previous treatment, risks, goals and monitoring.
Can GLP-1 treatment be used during pregnancy?
These weight-management medicines should not be used during pregnancy. Tell the clinician if you are pregnant, breastfeeding or planning pregnancy.
Will I need blood tests?
Not everyone needs the same tests. The doctor may recommend observations, blood tests or an in-person assessment depending on history, symptoms and medicines.
Does the free pre-check approve treatment?
No. It is screening only. A registered clinician makes the final prescribing decision after assessment.
