At DefineMD, we go beyond BMI — our physicians look at the full picture to build a plan tailored to your biology, your goals, and your life.
BMI is a screening tool and does not diagnose disease or body composition. Results should be interpreted in the context of a full medical evaluation. DefineMD physicians provide comprehensive assessments that consider BMI alongside labs, hormones, history, and individual health factors.
