  • Moderate: interferes with normal activities such as playing, school or sports
  • Severe: can't stand, needs support to walk, feels like passing out now

After Care Advice

Overview:
  • Not drinking enough fluids and being a little dehydrated probably caused the dizziness.
  • It should go away with drinking fluids and resting in a cool place.
  • This is always made worse during hot weather. Too much sun exposure can also increase the body's need for fluid.
  • Here is some care advice that should help.
Fluids:
  • Drink several glasses of fruit juice, other clear fluids or water.
  • This will improve your child's fluid status and blood sugar.
  • If the weather is hot, make sure the fluids are cold.
Cool Off:
  • If the weather is hot, use a cold pack or washcloth to the forehead.
  • Taking a cool shower or bath will help even more.
Rest:
  • Lie down with feet up for 1 hour.
  • Reason: This will increase blood flow to the brain.
Prevention:
  • Extra water and salty foods during sports or hot weather
  • Regular mealtimes and snacks
  • Enough sleep and rest
What to Expect:
  • With treatment, the dizziness usually goes away in 1 to 2 hours.
