Dehyration (hypohydration) is the removal of water (hydro in ancient Greek) from an object. In Physiologic terms, it entails a relative deficiency of water molecules in relation to other dissolved solutes. Dehydration, thus, is slightly different from hypovolemia, which defines water deficiency only in terms of overall volume rather than in terms of solute concentrations.
