An apparatus for measuring a body fluid includes: an optical sensor configured to emit light onto an object, receive the light returning from the object, and measure a first intensity of a first wavelength and a second intensity of a second wavelength from the received light； and a processor configured to estimate a body fluid volume of the object based on the first intensity and the second intensity.
