Approach

The diagnosis of volume depletion relies on clinical suspicion, careful history, and physical examination, supported by appropriate laboratory investigation.

Children and older people are at most risk due to their more limited capability to compensate for volume loss and potentially diminished capacity to communicate symptoms. Other risk factors include diuretic therapy and reduced levels of consciousness with limited access to fluids.
