Dehydration: How to Know
- Dehydration means that the body has lost too much fluid. This can happen with vomiting and/or diarrhea. A weight loss of more than 3% is needed. Mild diarrhea or mild vomiting does not cause this. Neither does a small decrease in fluid intake.

- Decreased urine no urine in more than 8 hours happens early in dehydration. So does a dark yellow color. If the urine is light straw colored, your child is not dehydrated.
- Dry tongue and inside of the mouth. Dry lips are not helpful.
- Dry eyes with decreased or absent tears
- In babies, a depressed or sunken soft spot
- 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.

- If the stools contain mucus, blood or smell bad, this points to diarrhea.
- Other clues to diarrhea are poor eating, acting sick, or a fever.
