Vitamin A Deficiency: Causes, Symptoms, and Treatment

Causes of Vitamin A Deficiency

Vitamin A deficiency occurs when a person’s diet lacks sufficient amounts of this essential nutrient. Several factors contribute to this condition, which can have significant health consequences. Below are some common causes of vitamin A deficiency:

Dietary Insufficiency: The most prevalent cause of vitamin A deficiency is a diet that lacks foods rich in this vitamin. It commonly affects individuals living in impoverished areas with limited access to diverse and nutritious food sources.
