What are the consequences of Vitamin A deficiency?

Vitamin A deficiency primarily leads to vision problems, particularly affecting the ability to see in low light conditions, which is referred to as night blindness. This nutrient is essential for the formation of rhodopsin, a pigment found in the retina that is critical for vision in dim light. Insufficient levels of Vitamin A can also lead to dry eyes and more severe conditions like xerophthalmia, which can result in permanent blindness if not addressed.

While other options such as increased fatigue, muscle cramping, and a weak immune response are health concerns associated with various nutritional deficiencies, they are not specifically tied to Vitamin A deficiency. Vitamin A plays a significant role in supporting the immune system by maintaining the health of skin and mucosal cells, but the most notable and immediate consequences of its deficiency are related to vision.
