Dehydration occurs when you lose more fluid than you take in. If lost fluid remains unreplenished you may suffer serious consequences.
Common causes of dehydration include intense bouts of diarrhea, vomiting, fever or excessive sweating. Inadequate intake of water during hot weather or exercise.
Signs and symptoms:
Dry, sticky mouth
Sleepiness or tiredness
Headache, dizziness or lightheadedness
Decreased urine output-fewer than six wet diapers a day for infants in eight hours.
Lack of sweating
In infants, sunken fontanels –the soft spot on top of the head
Delirium or unconsciousness
Unfortunately, thirst is not a reliable gage of the body's need for water. A better barometer is the color of your urine, clear or light–colored urine means you are well hydrated, where as a dark yellow or amber color is usually signs of dehydration.
