Water balance depends on an intact regulating mechanism for volume and osmolality. While thirst has a very important function in osmoregulation, in repletion of volume deficits it is of little importance. A thirst deficit is common in old persons and often a cause of dehydration in geriatric patients. Diagnosis, treatment and prevention of dehydration are discussed.
水平衡取决于完整的容量和渗透压调节机制。虽然口渴在渗透压调节中具有非常重要的作用，但在补充容量不足方面作用不大。口渴缺乏在老年人中很常见，并且常常是老年患者脱水的一个原因。本文讨论了脱水的诊断、治疗和预防。
