Dehydration is the lose of more fluid than you take in. It makes it hard or even impossible for your body to work as it should. Drinking fluids can help mild dehydration. Severe dehydration needs immediate medical care.
To work properly, the body requires a certain amount of fluid and other elements, called electrolytes. Water is lost through normal body function like sweat, urine, bowel movements, and breathing. Drinking and eating helps to replace these fluids and electrolytes. Dehydration can occur if there is excess loss of fluids, poor intake of fluids, or a combination of both.
Severe diarrhea and vomiting is the most common cause of dehydration in young children. Older adults have a lower amount of water in their bodies. Medical conditions or medicine can further lower fluids in their bodies.
Dehydration is more common in young children and older adults.
