Maintaining the fluid balance
When the body loses more fluid than it has taken in, it can lead to dehydration. Without enough fluid, the body is unable to carry out the normal processes needed for it to function.
Dehydration can be classified as mild, moderate or severe. Mild dehydration may be reversed if treated promptly. However, if left untreated, it can quickly progress to severe dehydration, which is a life-threatening medical emergency.
