Undersecretion of a posterior pituitary hormone

The correct answer to the question is option C which states that the copious micturition without glucose in the urine could be due to undersecretion of a posterior pituitary hormone. Here is an explanation of why this is the correct answer:

Posterior Pituitary Hormone
The posterior pituitary gland secretes the hormone called antidiuretic hormone (ADH) or vasopressin. This hormone plays a crucial role in regulating the amount of water reabsorbed by the kidneys.

Role of ADH
ADH acts on the kidneys to increase the reabsorption of water, leading to a decrease in the volume of urine produced. When there is undersecretion of ADH, the kidneys do not reabsorb enough water, resulting in the production of large amounts of dilute urine (copious micturition).

Thirst
As a compensatory mechanism to cope with the excessive loss of water through urine, the individual may feel an increased sensation of thirst. This is the body's way of trying to maintain fluid balance.

Glucose in Urine
The absence of glucose in the urine indicates that the excessive urination is not due to conditions like uncontrolled diabetes, where high levels of glucose spill into the urine. Instead, it points towards a hormonal imbalance affecting water reabsorption in the kidneys.

Conclusion
In summary, when a person is passing out a large amount of urine, feeling thirsty, but their urine does not contain glucose, the cause could be undersecretion of a posterior pituitary hormone like ADH. This hormonal imbalance disrupts the normal water reabsorption process in the kidneys, leading to copious micturition and increased thirst.
