About Body Surface Area (BSA)

BSA is often used in medicine as a more accurate indicator of metabolic mass than body weight because it is less affected by abnormal adipose mass. Factors such as weight and height play a significant role in determining BSA.

The BSA Formula

One commonly used formula to calculate BSA is the Du Bois formula. Here's how it works:

BSA = 0.007184 × Weight0.425 × Height0.725

This formula considers the weight in kilograms and the height in centimeters.

Real-life Application

For instance, consider an adult weighing 70 kg and measuring 175 cm in height. Using the Du Bois formula, the BSA can be calculated as follows:

BSA = 0.007184 × 700.425 × 1750.725 = 1.86 m2

Hence, this person's BSA is approximately 1.86 square meters. BSA is especially critical in determining medication dosages. For instance, chemotherapy drugs are often dosed according to a patient's BSA.

Key Achievements

The Du Bois formula, proposed by Dr. Du Bois and Dr. Du Bois in 1916, is one of the most widely used BSA calculation formulas. Their contribution has greatly impacted the medical field, particularly in the areas of drug dosage calculations and the treatment of skin disorders, providing a more accurate method for patient assessment.

Understanding your BSA can be crucial in medical treatments and overall health assessment. However, it's essential to note that while the BSA calculation provides a good estimation, each individual is unique. Always consult with a healthcare professional for personalized advice.
