Dehydration is the loss of water from the body which increases serum sodium levels. When fluid intake reduces and the body fails to replace the fluid loss due to underlying problem dehydration occur.
Dehydration can affect kidney function and increase the risk of kidney stones.
It can also lead to loss of strength and stamina.
So it is very necessary to know the proportion of water to take and when to take it on daily basis. Giving lots of liquids to a child with diarrhea is more important than any medicine. If enough liquid is given, no medicine is usually needed in the treatment of diarrhea. The common cause of death in children with diarrhea is severe dehydration or loss of too much water from the body. By giving a child with diarrhea plenty of water ( best with sugar or honey and salt).
Dehydration can often be Prevented.
Most children who die from diarrhea die because they do not have enough water left in their bodies.
Dehydration results when the body loses more liquid than it takes in. This can happen with severe diarrhea, especially when there is vomiting as well. It can also happen in very serious illnesses when a person is too sick to take much food or liquid.
People of any age can become dehydrated, but dehydration develops more quickly and is most dangerous in kids. Take note that any child with watery diarrhea is in danger of dehydration.

Types of solution given to regain fluid loss are
Hypotonic solution: It has a lower osmotic pressure than the extracellular fluid e.g 0.45% normal saline.
Hypertonic solution: These have higher osmotic pressure than extracellular fluid e.g 10% D/W.
Isotonic solution: These are solutions that have the same osmotic pressure as that of the extracellular fluid e.g 0.9% normal saline, wronged lactate, 0.45% normal saline.
