How does age affect the ECW ratio?

Research using bioelectrical impedance analysis reveals that the ratio of extracellular water to total body water, or ECW ratio, increases significantly with age. This shift in fluid balance is a natural part of the aging process, reflecting a decrease in water inside the body's cells relative to the water outside them. Understanding how does age affect the ECW ratio is crucial for monitoring changes in body composition and potential health concerns associated with aging.
