Drinking coconut water is a great way to replace the electrolytes lost in the body due to vomiting or diarrhea. Electrolytes are minerals that help to maintain a proper balance of fluid in the body. They also keep the nervous system functioning properly. When you have an upset stomach, it is important to stay hydrated, especially if you are losing fluids. The liquids will help your body get back to normal following the symptoms of gastrointestinal viruses.
