Severe dehydration in children

Severe dehydration means:

  • The child's mouth and eyes may be extremely dry.
  • The child may pass little or no urine for 12 or more hours.
  • The child may not seem alert or able to think clearly.
  • The child may be too weak or dizzy to stand.
  • The child may pass out.

Severe dehydration is a medical emergency. Call 911 or other emergency services immediately.

By the time a child becomes severely dehydrated, there is no longer enough fluid in the body to carry enough blood to vital organs. Shock, which is a life-threatening condition, can develop quickly.
