D) increased intestinal absorption of calcium

Question

Quizplus · Accepted Answer

Vitamin D deficiency can lead to an increase in parathyroid hormone levels, which can cause bone resorption and the release of calcium from bones into the bloodstream. This can eventually lead to osteoporosis and bone fractures. Hypercalcemia (choice A) is actually a condition of too much calcium in the blood, which is unlikely in the case of vitamin D deficiency. An increase in bone mass (choice B) is also unlikely as vitamin D is necessary for bone remodeling, and a deficiency would lead to weaker bones. Increased intestinal absorption of calcium (choice D) is dependent on vitamin D, and would not be increased in the case of a deficiency.
