Which of the following is a symptom of dehydration?

A symptom of dehydration is an elevated temperature. When the body is dehydrated, it can lead to various physiological changes, including an increase in body temperature. This elevation often occurs as the body struggles to maintain its normal functioning without adequate fluid levels. Dehydration affects the body’s ability to regulate temperature, and individuals may experience fevers or elevated temperatures as a response.

In contrast, increased appetite is generally not associated with dehydration; instead, a lack of fluids can often lead to decreased appetite. Frequent urination typically indicates proper hydration as the body efficiently processes fluids, while weight gain may suggest fluid retention rather than a state of dehydration.
