Dehydration: How to Tell
The main risk of not drinking enough fluids is dehydration. This means the body has lost too much water. It is a reason to see a doctor right away. Your child may have dehydration if not drinking much fluid and:
- The urine is dark yellow and has not passed any in more than 8 hours.
- Inside of the mouth and tongue are dry.
- There are no tears if your child cries.
- Slow blood refill test: longer than 2 seconds. First, press on the thumbnail and make it pale. Then let go. Count the seconds it takes for the nail to turn pink again. Ask your doctor to teach you how to do this test.
- A child with severe dehydration becomes too weak to stand. They can also be very dizzy when trying to stand.
