Dipsogen

Definition
A dipsogen is an agent that causes thirst. (From Greek: dypsa: thirst and the suffix -gen, to create.)

Physiology
Angiotensin II is thought to be a powerful dipsogen, and is one of the products of the renin-angiotensin pathway, a biological homeostatic mechanism for the regulation of electrolytes and water.
