BMI calculator
Body Mass Index — a rough but useful starting point. BMI doesn't measure muscle, frame, or distribution; clinicians use it as one input among many.

What the categories mean

BMI and GLP-1 eligibility
Most clinicians consider GLP-1 weight-loss medications appropriate for BMI 30+, or BMI 27+ with weight-related comorbidities (high blood pressure, type 2 diabetes, sleep apnea, etc.). Your clinician confirms eligibility during your visit using your full picture, not BMI alone.
Numbers are the starting point
