  • The person is in shock from severe dehydration (faints, can't walk, is confused or is having trouble breathing)

Dehydration with the following symptoms should be evaluated and treated in an emergency room:

  • Little to no urination
  • Extreme thirst
  • Lack of tears
  • Dry mouth
  • Sunken eyes
  • Dizziness or lightheadedness
  • Rapid breathing and heartbeat
  • Lack of alertness
  • Blurred or double vision

Signs of food poisoning from eating a canned food:

  • Give a child an oral rehydration solution. Call your health care provider for age-appropriate dosing specifics.
  • Give an adult as much clear fluid as possible.

  • The person has kidney, liver, or heart disease and must restrict fluid intake.
  • The person develops sudden, severe abdominal pain.
  • Dehydration symptoms develop.
  • Symptoms fail to resolve after a week.
  • Gradually ease food back into the person's diet.
  • Start with bland, easy-to-digest food such as crackers, bananas, toast, rice, and chicken.
  • Avoid dairy, caffeine, and alcohol until recovery is complete.
  • If medical treatment is necessary, the person may receive fluids intravenously and anti-nausea medications.
