What condition results from poor absorption and utilization of Vitamin A?

Vitamin A deficiency is a condition that arises specifically from inadequate intake, absorption, or utilization of vitamin A in the body. This vitamin is crucial for numerous bodily functions, including vision, immune function, and skin health. When there is a deficiency, it can lead to a range of health issues such as night blindness, a weakened immune system, and, in severe cases, can cause total blindness.

The other conditions referenced do not directly pertain to vitamin A utilization. For instance, marasmus is a form of severe malnutrition characterized by energy deficiency, primarily resulting from a lack of protein and calories rather than a specific vitamin deficiency. Anemia refers to a condition often related to iron deficiency or other forms of inadequate blood cell production but is not specifically connected to vitamin A. Iodine deficiency disorder pertains to the lack of iodine in the body, which affects thyroid function rather than vitamin A levels. Thus, only vitamin A deficiency directly relates to the poor absorption and utilization of the vitamin itself.
