What does a high level of specific gravity in urine indicate?

A high level of specific gravity in urine indicates dehydration. When the body is dehydrated, it tends to conserve water, resulting in the production of more concentrated urine. This concentration increases the specific gravity because specific gravity is a measure of the density of urine compared to pure water. Concentrated urine contains a higher amount of solutes, such as electrolytes and waste products, which contribute to this higher density.

Maintaining proper hydration is essential for various bodily functions, including kidney function, and a high specific gravity can serve as a signal to medical professionals that the patient may need to increase their fluid intake to avoid potential complications associated with dehydration.
