Overview

Micronutrient deficiencies are states of insufficient vitamins or minerals required in small quantities for normal metabolism, growth, and immune function. Often termed hidden hunger because they may occur without overt caloric undernutrition, they include deficiencies of vitamin A, the B-complex vitamins such as B12, vitamin D, iron, iodine, zinc, and folate. Causes encompass inadequate dietary intake and diversity, impaired absorption, increased physiological demand—as in pregnancy and childhood—and socioeconomic constraints on food access. Consequences are wide-ranging: vitamin A deficiency causes ocular and immune impairment, vitamin B12 deficiency causes hematologic and neurologic disease, and broad micronutrient shortfalls compromise growth, cognitive development, and resistance to infection. Assessment relies on dietary survey, anthropometry, and biochemical testing, while prevention emphasizes dietary diversification, fortification, and supplementation. Populations at heightened risk include pregnant women, adolescents, and young children, particularly in resource-limited settings. Research relevant to this area examines childhood micronutrient deficiency in relation to household economic status, vitamin B12 and vitamin A deficiency in children, nutritional deficiencies after bariatric surgery, dietary diversity and nutritional status among pregnant adolescents, and field assessment of nutritional status. This peer-reviewed nutrition literature reflects the etiology, populations, and public-health responses to micronutrient deficiency, situating vitamin and mineral inadequacy within the broader study of nutrition and Obesity Management.
