How much weight is lost when dehydrated?

How long does it take to rehydrate your body?

It takes minutes to hours to start feeling better from hydration, but full rehydration varies from 45 minutes for mild cases to days for severe dehydration, depending on fluid loss, body absorption (faster on an empty stomach), and if electrolytes are needed. Mild dehydration (after exercise) might resolve in 2-3 hours, while moderate cases (vomiting/diarrhea) could take a day or more, with severe dehydration sometimes requiring hospital IVs for days. 

What is the fastest way to reverse dehydration?

The fastest way to cure mild dehydration is to slowly sip fluids containing electrolytes, like oral rehydration solutions (ORS), sports drinks, or coconut water, especially after sweating, vomiting, or diarrhea, while water works for simple thirst; severe cases need immediate medical help, possibly requiring IV fluids, so see a doctor if symptoms are intense or persistent.
