10 Frequently Ignored Signs of Vitamin A DeficiencyIntroduction

Vitamin A is one of the most essential nutrients for the human body. It supports healthy vision, strengthens the immune system, promotes cell growth, and helps maintain the health of the skin and internal organs. Many people do not obtain enough vitamin A from their diet, despite its significance. The early symptoms of deficiency are often overlooked because they may appear mild or unrelated. However, if left untreated, a vitamin A deficiency might eventually cause major health issues.

In this article, we’ll discuss ten symptoms of vitamin A deficiency that are often ignored, helping you identify the signs early and protect your long-term health.

1. Poor Night Vision

Night blindness, or the inability to see in low light or at night, is one of the earliest symptoms of vitamin A insufficiency. Vitamin A is necessary for the retina to produce rhodopsin, a pigment that helps the eyes adjust to darkness. If you find yourself struggling to see while driving at night or moving around dimly lit spaces, it could be an early warning sign.

2. Dry Eyes and Eye Irritation

Vitamin A keeps the eyes lubricated by supporting tear production. Without enough of it, you may experience dry eyes, burning sensations, or frequent irritation. In severe cases, prolonged deficiency can lead to xerophthalmia, a condition that causes the cornea to become dry and damaged, potentially resulting in blindness.

3. Frequent Infections

Vitamin A is known as an “immune-boosting” vitamin. It plays a central role in producing white blood cells that fight infections. People with low levels of vitamin A are more likely to experience frequent illnesses such as respiratory infections, urinary tract infections, or skin infections. If you feel like you “catch everything,” vitamin A deficiency may be a hidden factor.
