Fevers, stomach flus, being out in hot weather, or too much exercise, for example, may result in too much fluid loss. This can lead to dehydration.
Dehydration isn’t something to take lightly. When it happens, the body doesn’t have enough fluids and water to function properly. In severe cases, your child can become delirious or unconscious. Dehydration could lead to brain damage or even death.
