What Are the Causes of Dehydration?

Every day we lose fluid and electrolytes via urine, sweat, saliva, and other bodily fluids. Usually, a normal, healthy diet will serve to replace lost electrolytes and fluid. But certain conditions or activities can lead to inadequate levels of fluid and electrolytes within our bodies. This is called dehydration.

Common causes include:
