Can you reverse damage from dehydration?

By drinking more fluids, you can typically treat any bout of mild hydration. More moderate to severe cases of dehydration may require hospitalization for treatment with IV fluids. Left untreated, severe dehydration can lead to serious complications, including electrolyte imbalances, organ failure and death.
