What does low urine specific gravity indicate in a patient with Diabetes Insipidus?

• A. Dehydration
• B. Overhydration
• C. Normal kidney function
• D. High blood glucose

Answer: (B)

Low urine specific gravity indicates that the urine is very dilute, which is characteristic of a patient with Diabetes Insipidus. This condition is defined by the body's inability to concentrate urine due to either a deficiency of the hormone vasopressin (antidiuretic hormone) or a resistance to its action. In Diabetes Insipidus, the kidneys lose the ability to retain water, leading to the production of large volumes of dilute urine. Therefore, when urine specific gravity is low, it reflects that the kidneys are excreting excess water rather than concentrating it, indicating that the patient may be experiencing overhydration or fluid excess, given that less solute is present in the urine. This finding is crucial for managing patients with Diabetes Insipidus, as it informs treatment strategies aimed at balancing fluid intake and maintaining hydration status. Hence, the identification of low urine specific gravity as a sign of overhydration becomes integral in understanding and addressing the clinical needs of the patient.
