Causes of Dehydration
You can lose more water than usual with: A fever, Diarrhea, Vomiting, Excessive sweating, Peeing a lot (Diabetes and some medications like water pills -- also called diuretics -- can make you pee more often.)
You may not replace the water you lose because:
> You’re busy and forget to drink enough.
> You don’t realize you’re thirsty.> You don’t feel like drinking because you have a sore throat or mouth sores, or you’re sick to your stomach.
Symptoms of Dehydration
Thirst isn't always a reliable early indicator of the body's need for water. Many people, particularly older adults, don't feel thirsty until they're already dehydrated. That's why it's important to increase water intake during hot weather or when you're ill. The signs and symptoms of dehydration also may differ by age.
