Common questions about BMI
What is BMI?
Body Mass Index (BMI) is a calculation that uses your height and weight to estimate body fat. It's a screening tool used by doctors to flag potential weight-related health risks.
What BMI qualifies for GLP-1 medications?
FDA-approved GLP-1 medications like Wegovy and Zepbound are typically prescribed for adults with a BMI of 30 or greater (obesity), or BMI of 27+ with at least one weight-related condition such as type 2 diabetes, high blood pressure, or high cholesterol.
Is BMI accurate?
BMI is a useful screening tool but it's not perfect. It doesn't distinguish between muscle mass and fat, so very muscular people may have a high BMI without excess body fat. Use BMI as a starting point, then talk to a licensed physician for a complete assessment.
