BMI calculator — GLP-1 eligibility check

Body Mass Index (BMI) is a screening measure of body weight relative to height. For FDA-approved GLP-1 weight management medications (Wegovy®, Zepbound®, Ozempic®), eligibility is typically BMI ≥30, or BMI ≥27 with at least one weight-related comorbidity (hypertension, type 2 diabetes, high cholesterol, sleep apnea). Use this calculator to estimate your BMI, then complete a brief intake to be evaluated by an independent, board-certified physician on the FirstCall platform for program eligibility.

Eligibility Criteria

GLP-1 eligibility thresholds explained

GLP-1 Eligible
BMI 30 or above

The primary eligibility threshold for all FDA-approved GLP-1 weight loss medications. No comorbidity required.

Wegovy® injection (semaglutide 2.4mg weekly)
Wegovy® pill (oral semaglutide 25mg daily)
Zepbound® (tirzepatide 5–15mg weekly)
Compounded semaglutide available through licensed pharmacies
Eligible with Comorbidity
BMI 27–29.9 with comorbidity

GLP-1 eligibility begins at BMI 27 when at least one qualifying weight-related condition is present.

High blood pressure (hypertension)
Type 2 diabetes or prediabetes
High cholesterol or dyslipidemia
Obstructive sleep apnea
Cardiovascular disease
Not Currently Indicated
BMI under 27

GLP-1 medications are not FDA-approved for weight loss below BMI 27. A physician can discuss evidence-based alternatives.

Important: BMI is a screening tool, not a complete clinical assessment. Some patients below the BMI threshold have clinical factors that make GLP-1 therapy appropriate; others above the threshold may have contraindications. A free physician evaluation provides the complete picture.

Common Questions

BMI & Eligibility FAQs

Understanding the eligibility criteria for GLP-1 treatment.

BMI is the primary threshold in FDA approval criteria but not the only factor. Your physician evaluates your complete health profile — including comorbidities, cardiovascular risk, medications, thyroid history, and kidney function — before recommending a treatment approach.
Yes. BMI 27–29.9 with hypertension (high blood pressure) qualifies for FDA-approved GLP-1 weight loss medications including Wegovy® and Zepbound®. A free physician evaluation will confirm eligibility and recommend the best medication for your profile.
Yes. BMI 30+ qualifies for GLP-1 treatment without requiring any comorbidity. Clinical benefits at BMI 30–35 include meaningful reductions in cardiovascular risk, blood pressure, and metabolic markers — even in patients who currently feel well.
BMI is a useful screening tool but has known limitations — it does not account for muscle mass, bone density, fat distribution, or metabolic health. Your physician uses BMI as one data point alongside labs, health history, and clinical judgment. The tool below gives you a starting point for that conversation.
