[Dipsogenic behavior].
Hydroelectrolytic homeostasis assumes balance between the intake and elimination of water and electrolyte, according to the necessities of the organism. The water intake is made mainly by fluid ingestion. The necessity to drink is a subjective sensation which is the expression of an objective situation, because it translates the homeostatic deviations. The ingestion of water is motivated (reparatory thirst), when it appears after hydric and electrolytic imbalances (ex. a decrease of the fluid volume, increase in the plasmatic osmolarity) or is manifested without an objective reason (unreparatory thirst).
