Dehydration occurs when the body has insufficient water to function properly. While mild dehydration may be just uncomfortable, more severe dehydration can lead to blood clots, seizures, and other potentially fatal complications.
Anyone may become dehydrated, but the condition is especially dangerous for young children and older adults.
The most common cause of dehydration in young children is severe diarrhea and vomiting. Older adults naturally have a lower volume of water in their bodies, and may have conditions or take medications that increase the risk of dehydration.
When you are dehydrated, your body doesn’t produce enough saliva.
‘If you’re not producing enough saliva, you can get bacteria overgrowth in the mouth, and one of the side effects of that is bad breath,’ says John Higgins.
Fever and Chills
If your body is severely dehydrated you may experience fever and chills. Fever, in turn, can worsen dehydration, and the higher the fever, the more dehydrated you may become.
