The Science of Dehydration
Dehydration and Fever
Risk of Dehydration during a Fever
A fever can be caused by conditions such as the common cold, influenza, infections (viral and bacterial) or gastroenteritis. During a fever, it is likely that the patient (especially children) will consume less food and fluids, due to ill health. Lack of food and fluid intake can put the person at risk of developing mild dehydration.
Additionally, during a fever a person can experience fluid and electrolyte loss, through sweat. This can also contribute to the development of mild dehydration.
The combination of food and water deprivation, with moderate sweating can sometimes lead to mild dehydration.
It is important to monitor for signs and symptoms of dehydration during a fever.
