BMI Calculator for GLP-1 Eligibility

FDA guidelines require a BMI of 30 or higher, or a BMI of 27 or higher with at least one weight-related health condition such as type 2 diabetes, high blood pressure, or high cholesterol.

BMI (Body Mass Index) is calculated by dividing your weight in kilograms by your height in meters squared. The formula is: BMI = weight (kg) / height (m)². Our calculator handles the conversion from imperial units automatically.

No. While BMI is the main screening number, your doctor will also look at your overall health, medical history, current medications, and any weight-related conditions you have. Some patients with a BMI of 27-29.9 may qualify if they have a related condition like high blood pressure, type 2 diabetes, high cholesterol, or sleep apnea.

Generally no. GLP-1 weight loss medications like Wegovy and Zepbound are FDA-approved for adults with a BMI of 30+, or a BMI of 27+ along with at least one weight-related health condition. Off-label prescribing at lower BMIs is rare and up to the provider.

Clinical trials show average weight loss of 15-22% of body weight over 68-72 weeks on maximum doses of semaglutide or tirzepatide. Individual results vary based on starting weight, medication, dosage, diet, and exercise.

Most insurance plans that cover GLP-1 weight loss medications require a documented BMI of 30+, or a BMI of 27+ with at least one weight-related condition (high blood pressure, type 2 diabetes, high cholesterol, or sleep apnea), along with proof of prior weight loss attempts. See coverage by insurer.
