A patient is diagnosed with a condition that impairs the production of Antidiuretic Hormone ADH . Based on the information provided, what physiological consequence would most likely result from this condition?

  • A: Increased water retention in the kidneys, leading to higher blood volume.
  • B: Decreased water retention in the kidneys, leading to increased urine production and potential dehydration.
  • C: Impaired milk secretion from mammary glands.
  • D: Abnormal regulation of blood glucose levels.

Explanation

Antidiuretic hormone ADH primarily functions to increase water retention in the kidneys. This means it reduces the amount of water excreted in urine, helping the body conserve water and maintain blood osmolarity. Therefore, if ADH production is impaired, the kidneys would be unable to retain sufficient water, leading to increased urine output polyuria and a risk of dehydration.
