(HealthDay News) -- Dehydration, if severe enough, can be life-threatening. While the obvious solution is to drink fluids, drinking even a little bit can sometimes make vomiting or nausea worse.
If you can't keep a small amount of water down, you should see a doctor as soon as possible.
The U.S. National Library of Medicine lists these warning signs of dehydration:
- Dryness or a sticky feeling in the mouth.
- Urine that is a dark yellow color.
- Not urinating as much as usual or not at all.
- Inability to produce tears.
- Eyes that appear sunken.
- When the "soft spot" at the top of a baby's head appears sunken.
- Feeling tired or having no energy.
