Dehydration occurs when your body loses too much water. This can happen if you do not drink enough fluids or lose a lot of fluid due to diarrhea, vomiting, sweating, or fever. Being dehydrated can cause health problems and can even be life-threatening.
To replace lost fluids, it helps to drink liquids that contain special minerals called electrolytes. Electrolytes keep your body working well. Plain water does not have electrolytes. You also need to rest to prevent more fluid loss.
