Abstract
A body water amount condition judging apparatus is provided wherein at least two values selected from intra-cellular water resistance, extra-cellular water resistance, a combined resistance of the intracellular and extra-cellular water resistance, and the ratio of intra-cellular and extra-cellular water are used as the judging parameters, which values are obtained based on the bioelectric impedance measured in multi-frequency bioelectric impedance measurement. Using these parameters, it is possible to judge the body water amount condition considering not only total body water amount condition, but each constituent component of body water as well.
