An overview on mechanism, cause, prevention and multi-nation policy level interventions of dietary iron deficiency

Abstract

Iron deficiency anemia (IDA) is probably the most ignored situation in the world of malnutrition—largely due to its slow progression. Multiple reasons can be attributed as the cause of IDA, which is not limited to any specific region or population; therefore, making it a matter of global concern. Despite the human body’s ability to absorb and conserve iron stores, the gradual loss due to various physiological conditions leads to net deficiency of iron. Countless commercial iron supplements are available, but at given physiological conditions, almost all of these “Bio-not-available” iron forms quite often become ineffective. World Health Organization and other government bodies have jointly developed health advisories and tried to developed nutrition supplements several times in the last two decades. IDA, when combined with other disease conditions, becomes a life-threatening situation. At the same time, an overdose of iron could also be very harmful to the body. Therefore, it is important to deal with this situation with caution. This article covers iron metabolism, available options for iron supplementation, regulatory aspects and strategies to prevent IDA.
