Micronutrient deficiency

Micronutrient deficiency refers to the sustained insufficient supply or intake of essential vitamins and minerals required in small amounts for normal growth, development, and maintenance of health. It is not itself a molecule or receptor but describes a pathological state resulting from inadequate dietary intake or absorption. Common deficiencies include iron, vitamin A, iodine, zinc and folate. These deficiencies can lead to serious health consequences such as anemia (from iron/folate/vitamin B12/vitamin A), impaired cognitive development in children, increased susceptibility to infections due to weakened immunity and other chronic health issues[1][3][5][9]. The term “hidden hunger” is often used because symptoms may be subtle until severe damage occurs. Micronutrient deficiencies are addressed through improved diet diversity/quality and public health interventions like food fortification and supplementation programs. Note on correctness: “Micronutrient deficiency” does **not** refer to any single molecular target such as an enzyme/receptor/transporter/protein; instead it describes a clinical/nutrition condition caused by insufficient levels of various essential nutrients[1][3]. Therefore this entry should be flagged as incorrect if intended for use in databases cataloging druggable molecular targets.
