  • Dehydration is a depletion in total body fluids.
  • Dehydration is first reflected in a diminution of blood volume - hypovolaemia.
    • The blood becomes hypertonic or hyperosmotic.
    • Fluid is withdrawn from the interstitial compartment.
  • If the dehydration continues, water is drawn from the cells.
    • Cellular dehydration impairs metabolic function, and death ensues.


  • Either:
    • Decreased intake due to lack of availability of water.
    • increased losses via
      • The skin (sweating)
      • The gut (diarrhoea)
      • The kidney (Renal disease).
