Sept. 17 -- (HealthDay News) -- If you don't drink enough water -- especially on a hot day -- you could become dehydrated. That's an obvious cause.

But a number of other things can cause dehydration, a potentially dangerous lack of bodily fluids.

The U.S. National Library of Medicine offers this list:

  • Having diarrhea or vomiting.
  • Urinating frequently, perhaps from uncontrolled diabetes or using diuretic medication.
  • Sweating excessively.
  • Having a fever.
  • Not eating due to nausea or lack of appetite.
  • Having a sore throat or painful sores in the mouth.
