Question

describe the method of measuring the amount of body water?

Answer 1

Bioelectrical impedance analysis. Another method of determining total body water percentage (TBW%) is via Bioelectrical Impedance Analysis (BIA). In the traditional BIA method, a person lies on a cot and spot electrodes are placed on the hands and bare feet.

Answer 2

The total body water is then accurately measured from the increase in breath deuterium content in relation to the volume of D2O ingested. Different substances can be used to measure different fluid compartments: total body water: tritiated water or heavy water. extracellular fluid: inulin.
