How to Calculate GLP-1 BMI Eligibility Checker

What is GLP-1 BMI Eligibility Checker?

The GLP-1 BMI Eligibility Checker determines whether you meet the FDA-approved BMI criteria for GLP-1 receptor agonist medications prescribed for weight management. It checks your BMI against approval thresholds and identifies qualifying weight-related comorbidities.

Formula

BMI = Weight (kg) / Height (m)²

W: Body Weight (lbs or kg) — Current body weight
H: Height (inches or m) — Standing height
BMI: Body Mass Index (kg/m²) — Calculated BMI value
C: Comorbidity Flag (yes/no) — Whether the patient has a qualifying weight-related comorbidity

Step-by-Step Guide

1Enter your weight and height to calculate your BMI
2Select any weight-related comorbidities you have (type 2 diabetes, hypertension, dyslipidemia, sleep apnea)
3The calculator checks your BMI against FDA eligibility thresholds: BMI >= 30, or BMI >= 27 with at least one comorbidity
4View your eligibility status and which specific GLP-1 medications you may qualify for

Worked Examples

Input

Weight: 195 lbs, Height: 5'8" (BMI 29.7), has hypertension

Result

BMI 29.7 with hypertension comorbidity — ELIGIBLE for Wegovy/Zepbound (BMI >= 27 with comorbidity threshold met)

Input

Weight: 160 lbs, Height: 5'6" (BMI 25.8), no comorbidities

Result

BMI 25.8 without comorbidities — NOT ELIGIBLE under current FDA criteria (requires BMI >= 30, or >= 27 with comorbidity)

Common Mistakes to Avoid

✕Confusing obesity medication eligibility (BMI 27/30) with diabetes medication eligibility (no BMI requirement for Ozempic/Mounjaro)
✕Not knowing that obstructive sleep apnea, PCOS, and NAFLD count as qualifying comorbidities
✕Using outdated BMI thresholds that do not reflect ethnicity-specific criteria recommended by some guidelines

Frequently Asked Questions

What BMI do I need for Wegovy or Zepbound?

FDA approval requires a BMI of 30 or greater (obesity), OR a BMI of 27 or greater (overweight) with at least one weight-related condition such as type 2 diabetes, high blood pressure, or high cholesterol. Your prescriber makes the final determination.

Can I get GLP-1 medication if my BMI is normal but I want to lose weight?

No, GLP-1 medications for weight management are not FDA-approved for patients with a normal BMI (under 25). Off-label prescribing is at the physician's discretion but is not supported by current guidelines and unlikely to be covered by insurance.

Does BMI eligibility differ by ethnicity?

Some medical organizations recommend lower BMI thresholds for Asian populations (BMI >= 25 for obesity, >= 23 for overweight) due to higher metabolic risk at lower BMI levels. However, FDA labeling currently uses standard thresholds. Discuss ethnicity-specific risks with your provider.
