The short answer

Wegovy and Zepbound are approved for adults with a BMI of 30 or more, or 27 or more with at least one weight-related condition such as type 2 diabetes, high blood pressure, high cholesterol or sleep apnea. BMI is weight in kilograms divided by height in metres squared. Meeting the number is the first screen, not a prescription: a clinician still checks the contraindications in the labels.

Check your BMI against the label criteria

Weight-related conditions diagnosed by a clinician (optional)

Enter your height and weight to see your BMI and how it maps to the label criteria.

Criteria are from the FDA prescribing information for Wegovy and Zepbound for adults, as set out in our eligibility guide, which also lists the contraindications (a personal or family history of medullary thyroid carcinoma or MEN 2, pancreatitis history, pregnancy and others) that this tool does not check. Meeting the BMI criterion is not a prescription: a licensed clinician decides. Nothing you enter here is stored or sent.

What the result means

The calculator reports the standard adult BMI categories and then states which, if any, of the label criteria your number meets. It is deliberately conservative: a BMI between 27 and 29.9 is reported as meeting the criteria only when you tick a weight-related condition, because that is what the prescribing information requires, and a BMI below 27 is reported as not meeting them.

The four conditions listed are the ones named as examples in the labels. They are not the only ones a clinician can document, and the telehealth providers we review each publish their own intake rules. Our guide to who qualifies for GLP-1 weight-loss medication walks through the criteria, the contraindications and what each provider states.

If your number meets the criteria and you are comparing providers, the cost calculator multiplies every verified price out over the months you choose, and the provider guide covers the checks that matter beyond price.

Frequently asked questions

How is BMI calculated?

BMI is weight in kilograms divided by height in metres squared. In imperial units it is weight in pounds divided by height in inches squared, multiplied by 703. The calculator does that arithmetic and nothing else; it does not store or send what you enter.

What BMI do you need for Wegovy or Zepbound?

The prescribing information for both medications covers adults with a BMI of 30 or more, or a BMI of 27 or more with at least one weight-related condition such as type 2 diabetes, high blood pressure, high cholesterol or obstructive sleep apnea. Those are the criteria the calculator checks against.

Does meeting the BMI criterion mean I will be prescribed a GLP-1?

No. BMI is one criterion. A clinician also screens for contraindications in the labels, including a personal or family history of medullary thyroid carcinoma or MEN 2, pregnancy, and a history of pancreatitis, and reviews your other medications. Each telehealth provider also applies its own intake criteria.

What are the limits of BMI?

BMI does not distinguish muscle from fat, does not account for where fat is carried, and uses the same thresholds for everyone. A muscular adult can have a high BMI with little body fat, and some groups carry health risk at lower BMIs. It is a screening number, which is why the labels pair it with weight-related conditions rather than using it alone.

Do online GLP-1 providers use the same criteria?

The providers we review publish their own eligibility criteria, and most reference the same BMI thresholds as the labels. Compounded semaglutide and tirzepatide are not FDA-approved products, so for those the provider's clinician, not a label, decides who is prescribed. Our eligibility guide lists what each provider states.

Medical disclaimer

This page is general information about GLP-1 weight-loss medications such as semaglutide and tirzepatide, published to help you compare services. It is not medical advice, it does not create a doctor-patient relationship, and it is not a substitute for a consultation with a licensed clinician who knows your history. Treatments Hub is not a medical provider, pharmacy or clinic and does not prescribe, sell or dispense medication. Do not start, stop or change any treatment because of something you read here, and do not delay seeking care; in an emergency call 911.

Semaglutide and tirzepatide carry an FDA boxed warning about thyroid C-cell tumours seen in rodents and are not for anyone with a personal or family history of medullary thyroid carcinoma or MEN 2, nor for use in pregnancy. Compounded versions sold by telehealth providers are prepared by state-licensed pharmacies and are not FDA-approved products. Where a review or post on this page mentions weight lost, that is one person's result and is not typical; results vary widely.

Medical and scientific statements on this site are checked against the sources linked on the page by our medical content reviewer, who does not choose providers or set prices. Prices, plans and customer reviews are each provider's published figures and customers' own words on the dates stated. We may earn a commission from provider links.
