How long can an elderly person live without water?

Answer 1

A person will probably die without water after 5 days, but will suffer serious, effects after 3 days. Death by dehydration is a nasty process involving incessent skin irritation, halucinations, and the swelling/ cracking of the tongue. 3 days without water is a serious threat to survival. All of the figures that I have read say 10 to 20 days without food. Obviously, this depends upon your weight to begin with and your state of health before the eating stopped. An overweight adult will last longer because they have more reserves to work from than a thin person.

Answer 2

For a healthy person, three days are the limit for how long one can survive without water. However, with a terminally ill person, the body is weakened and may survive for up to three weeks without water.

Answer 3

This depends on the persons existing state of hydration, but usually would be only a matter of days after removal of a feeding tube.

Answer 4

People, of all ages, can only live 72 hours without water.
