How Does Our Body Respond To Vitamin A Deficiency?

Vitamin A deficiency is a very common problem in developing countries that do not have access to the Vitamin A rich foods that the United States does.

The World Health Organizations estimates that approximately 250,000 to 500,000 undernourished children in Third World countries become blind every year as a result of Vitamin A deficiency. In the United States, Vitamin A deficiency is rare, but when it does occur, it is associated with severe dietary restrictions and extreme intake of alcohol. A Zinc deficiency will often accompany a Vitamin A deficiency as Zinc is necessary to create the binding proteins that transport Vitamin A throughout our bodies. A deficiency of zinc will limit our body's ability to transport stores of Vitamin A from the liver to the tissues in the body.

The first sign of a Vitamin A deficiency is generally night blindness. Vitamin A deficiency will contribute to blindness by drying up the cornea of the eye and damaging both the retina and cornea simultaneously. A Vitamin A deficiency will also inhibit the body's capacity to fight infections. It is because of this that many children will die from a Vitamin A deficiency as they live in countries where immunization is limited and they will die from infectious diseases such as measles and pneumonia. In Vitamin A deficiencies, cells that line the lungs lose the capacity to rid the lungs of disease causing bacteria, and thus pneumonia ensues.

Those in the United States that are at risk for Vitamin A deficiency are in the following groups:

Preschool and toddler aged children
Children living below the poverty line
Children with no access to health care or immunization programs
Children living where there is known nutritional deficiencies
Immigrants or refugees that have arrived in America recently from Third World countries that have high rates of either Vitamin A deficiency or measles
Children that have known diseases of pancreas, liver, bowels, or not enough fat digestion or absorption
