Dehydration

Dehydration is the condition in which body water output exceeds water input. Dehydration may develop with either water deprivation or excessive water loss. Symptoms include thirst, dry skin and mouth, rapid heartbeat, low blood pressure, weakness, exhaustion, and delirium. If not corrected, dehydration will end in death. When water intake is inadequate, the blood becomes concentrated. The mouth becomes dry, and the brain initiates drinking behavior. The first signal is thirst. Thirst drives one to seek water, but lags behind the body’s need because by the time thirst is felt the body has already lost some of its water.
