BMI Calculator for GLP-1 Eligibility

Q: What BMI do you need for GLP-1 medications?

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.

Q: How is BMI calculated?

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.

Q: Is BMI the only factor for GLP-1 eligibility?

No. While BMI is the primary screening criterion, your doctor will also consider your overall health, medical history, current medications, and weight-related conditions. Some patients with a BMI of 27-29.9 may qualify if they have comorbidities like hypertension or sleep apnea.

Q: Can I get GLP-1 medications with a normal BMI?

Generally no. GLP-1 weight loss medications like Wegovy and Zepbound are FDA-approved for adults with obesity (BMI 30+) or overweight (BMI 27+) with comorbidities. Off-label prescribing is rare and at the provider's discretion.

Q: How much weight can I expect to lose on GLP-1 medications?

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.

Q: Does insurance cover GLP-1 medications based on BMI?

Most insurance plans that cover GLP-1 weight loss medications require documented BMI of 30+ or BMI 27+ with comorbidities, along with proof of prior weight loss attempts. Learn more about insurance coverage .
