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, or sweating. Being dehydrated can cause health problems and can even be life-threatening.
To replace lost fluids, you need to drink liquid that contains special chemicals called electrolytes. Electrolytes keep your body working well. Plain water does not have electrolytes. You also need to rest to prevent more fluid loss. Replacing water and electrolytes (oral rehydration) completely takes about 36 hours. But you should feel better within a few hours.
Follow-up care is a key part of your treatment and safety. Be sure to make and go to all appointments, and call your doctor or nurse call line if you are having problems. It's also a good idea to know your test results and keep a list of the medicines you take.
