Health Tip: What Can Cause Dehydration?

(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.
