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.

GLP-1 eligibility requires BMI ≥30, or BMI ≥27 with at least one weight-related comorbidity.
GLP-1 eligibility thresholds explained
The primary eligibility threshold for all FDA-approved GLP-1 weight loss medications. No comorbidity required.
GLP-1 eligibility begins at BMI 27 when at least one qualifying weight-related condition is present.
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.
