Dehydration occurs when the body does not have a sufficient amount of fluids to properly function and you lose more fluids are consumed. This can easily occur on a hot day when your body produces sweat to stay cool, or when you are sick and vomit or have diarrhea.
Mild dehydration can usually be treated at home simply by drinking more fluids. Moderate cases of dehydration may require you to visit the hospital and receive fluids intravenously of through an IV. Severe dehydration should be considered a medical emergency as it can be fatal when it is not treated. If necessary, go to the nearest hospital, quick care clinic or urgent care center for treatment.
Dehydration can happen to anyone at any age including infants, young children, and older adults who are at a higher risk for becoming dehydrated.
