Often the first symptom a person with dehydration experiences is thirst. By the time thirst is experienced, dehydration is already occurring. Not all people, especially the elderly, may experience or be aware of thirst in the early stages of dehydration. Other symptoms may include dry mouth, dry lips, sunken eyes, inability to make tears and little or no urine production.
In infants symptoms of dehydration may include a sunken fontanel (soft spot) on the top of the head, no tears with crying, and fewer wet diapers.
