What is a common complication of Vitamin A deficiency?

Vitamin A deficiency is well-known for its specific association with several health complications, one of the most notable being night blindness. This condition occurs because Vitamin A is a crucial component of rhodopsin, the pigment in the retina that is essential for low-light and nighttime vision.

When there is inadequate Vitamin A in the body, the production of rhodopsin is impaired, which leads to difficulty seeing in dim light conditions. This effect highlights the vital role that Vitamin A plays in maintaining eye health and function. Night blindness serves as an early warning sign of Vitamin A deficiency before more severe ocular issues, such as xerophthalmia (a condition that can lead to corneal damage), may develop.

The other options relate to different vitamins, proteins, or overall nutritional issues but do not specifically correlate with Vitamin A deficiency as closely as night blindness does. For instance, goiter is typically linked to iodine deficiency, while protein-energy malnutrition and kwashiorkor are associated with a lack of protein and overall calories in the diet, rather than a specific vitamin deficiency.
