Which of the following conditions is NOT typically associated with Vitamin A deficiency?

• A. Night blindness
• B. Dry or cracked skin
• C. Increased thirst and urination
• D. Damage to the cornea

Answer: (C)

Vitamin A deficiency primarily affects vision and skin health, leading to specific conditions. Night blindness occurs as a direct result of insufficient Vitamin A, which is essential for the formation of rhodopsin in the retina that allows for low-light vision. Damage to the cornea, such as xerophthalmia, is another classic sign of Vitamin A deficiency, as the vitamin is crucial for maintaining the integrity of epithelial tissues, including those in the eyes. Dry or cracked skin can also be associated with Vitamin A deficiency due to its role in skin health and cellular differentiation. A lack of Vitamin A can lead to hyperkeratosis, a condition where the skin becomes dry and rough. Increased thirst and urination, however, are typically associated with conditions such as diabetes mellitus or diabetes insipidus, and not with Vitamin A deficiency. This symptom is indicative of disruptions in glucose metabolism or fluid regulation, rather than a deficiency of this specific vitamin. Thus, it is clear the correct answer pertains to the condition least connected to Vitamin A deficiency.
