Which of the following is a common sign of dehydration?

Dry mouth and decreased urine output are well-documented signs of dehydration. When the body lacks adequate fluids, it prioritizes the conservation of water, leading to less urine production. Consequently, urine may become concentrated, often resulting in a darker color. A dry mouth occurs as a direct result of decreased saliva production, which is another symptom of insufficient fluid intake.

Understanding these signs is important, especially in settings where individuals may be at higher risk for dehydration, such as the elderly or those with certain medical conditions. Recognizing dehydration early can facilitate timely intervention and help prevent more serious complications.
