What is Body Surface Area (BSA)?

Body Surface Area (BSA) is a measurement of the total surface area of the human body, commonly used for medical dosing, metabolic health assessment, and fitness tracking.

How do I calculate my Body Surface Area?

BSA is calculated using formulas such as the DuBois, Mosteller, or Haycock method, which factor in height and weight to determine the body's total surface area.

Why is BSA important in medicine?

BSA is crucial for determining accurate drug dosages, particularly in chemotherapy and pediatric medicine, ensuring safe and effective treatment.

How does BSA relate to fitness and metabolism?

BSA helps estimate metabolic rate and caloric needs, offering a more precise assessment than BMI for those managing weight, muscle mass, or overall health.
