What causes dehydration?
The reasons of dehydration of the body are diverse. The normal body’s state of hydration is a matter of proper balance between the water consumed and water excreted. The reason of the dehydration may be simple, as drinking not enough water, and as more complicated as abnormal water quantity loss with diarrhea or vomiting.
Medical drugs can also increase fluid loss. As the body receives water through the intestine any disorders in the intestinal absorption (after surgery, for example) lead to dehydration.
