(HealthDay News) -- Dehydration occurs when the body doesn't have enough fluids to continue working properly.
If you don't drink enough fluids or have diarrhea, your risk of dehydration rises. This can be especially dangerous for older people or those with weaker immune systems.
The U.S. National Digestive Diseases Information Clearinghouse says anyone with these warning signs should see a doctor as soon as possible to be evaluated for dehydration:
- Feeling thirsty.
- Not urinating often or noticing that urine is very dark.
- Having dry skin.
- Fainting or feeling dizzy.
- Being tired.
- Having skin that doesn't quickly return to normal after being pinched.
