Question

When you don't have enough ADH are you retaining water or losing water?

a) Retaining water
b) Losing water
c) No effect on water balance
d) Increased thirst

Answer 1

A deficiency in ADH results in the body losing water, not retaining it, leading to increased urine output and thirst.

Step-by-step explanation:

When there is a deficiency of Antidiuretic Hormone (ADH), the condition is characterized by the loss of water from the body. ADH plays a critical role in helping the body retain water by making the kidneys reabsorb water. Without sufficient levels of this hormone, the kidneys expel more water, resulting in increased urine production and a consequential rise in thirst. This can potentially lead to dehydration and requires continuous intake of water to compensate for the loss. In contrast, the normal function of ADH allows the body to conserve water, especially in times of dehydration or high osmolality, such as during stress. Conversely, when you consume substances like alcohol, ADH production is reduced, further promoting water loss.
