Dehydration:
Dehydration occurs when your body loses more fluid than you take in. When the normal water content of your body is reduced, it upsets the balance of minerals (salts and sugar) in your body, which affects the way it functions.

Symptoms can be severe in some people, particularly the young and the elderly.
