Körperfläche

Körperfläche, also known as body surface area (BSA), is a measurement that represents the total external surface area of the human body. It is commonly used in medicine and physiology to assess and compare the size of an individual's body in relation to various biological and clinical parameters. Unlike body weight or height, Körperfläche provides a more comprehensive indicator of the body's physical scale, which can influence physiological processes such as heat exchange, drug metabolism, and fluid regulation.

Körperfläche is typically expressed in square meters (m²) and varies depending on factors such as age, gender, and overall body composition. It is especially relevant in dosing medications, including chemotherapy, where precise calculations are necessary to minimize toxicity and maximize efficacy. The measurement can be estimated through several formulas, with the Mosteller formula being one of the most common due to its simplicity and accuracy. The Mosteller formula calculates BSA as the square root of (height in centimeters multiplied by weight in kilograms divided by 3600).

Physiologically, Körperfläche plays a vital role in thermoregulation—larger surface areas facilitate heat dissipation, while smaller areas conserve heat. In clinical settings, body surface area is also used to evaluate nutritional status and body size relative to population data. It is a fundamental parameter in pediatric and geriatric medicine, where standard growth and aging processes influence body proportions.

Understanding Körperfläche is essential for tailored medical treatment and research, enabling healthcare professionals to make informed decisions based on individual body size and related biological functions.
