Which is a common sign of dehydration in elderly patients?

Dry mouth is a common sign of dehydration in elderly patients. As individuals age, their bodies become less efficient at maintaining fluid balance, and they may not recognize thirst as effectively. A dry mouth occurs when there is insufficient saliva production, which is often due to a reduction in fluid intake or loss of fluids from the body. In elderly patients, dehydration can also lead to more severe symptoms, such as confusion, urinary tract infections, and constipation.

In contrast, increased appetite, heightened energy levels, and improved cognitive functions are not typical signs associated with dehydration. In fact, dehydration usually leads to decreased appetite and low energy levels, along with potential cognitive impairment, as the body’s systems are negatively affected by the lack of adequate hydration. Recognizing dry mouth as a sign of dehydration can help caregivers and healthcare providers intervene early to prevent further complications.
