Dehydration can be caused by losing too much fluid, not drinking enough water or fluids, or both.
Your body may lose too much fluids from:
Excessive sweating (for example, from exercise) Excessive urine output, such as with uncontrolled diabetes or diuretic use Fever Vomiting or diarrhea
You might not drink enough fluids because of:
Loss of appetite due to illness Nausea Sore throat or mouth sores
Dehydration in sick children is often a combination of refusing to eat or drink anything and losing fluid from vomiting, diarrhea, or fever. Infants and children are more likely to become dehydrated than adults because they weigh less and their bodies turn over water and electrolytes more quickly. The elderly and people with illnesses are also at higher risk.
