Abstract: An apparatus for estimating body water status includes a spectrometer having a light source configured to emit light onto an object, and a detector configured to measure a near-infrared (NIR) absorption spectrum by detecting light scattered or reflected from the object; and a processor configured to estimate an albumin concentration in the object based on the measured NIR absorption spectrum, and to estimate a body water index based on the estimated albumin concentration by using a body water index estimation model that represents a relationship between a change in the albumin concentration and a change in an amount of body water present in the object.
