INTERRELATIONSHIP OF ESSENTIAL TRACE ELEMENT METABOLISM IN ADOLESCENTS WITH NEUROCIRCULATORY DYSTONIA LIVING IN IODINE-DEFICIENT CONDITIONS
Abstract
Iodine deficiency remains a significant global health problem, particularly in regions where environmental and nutritional factors contribute to endemic goiter and related disorders. Adolescents are especially vulnerable to the consequences of iodine deficiency, as thyroid hormone regulation plays a vital role in growth, neurodevelopment, and cardiovascular adaptation. Neurocirculatory dystonia (NCD), a functional cardiovascular disorder common in adolescence, is strongly influenced by metabolic and endocrine imbalances. The present study aimed to investigate the interrelationship of essential trace elements, including iodine, zinc, copper, selenium, and iron, in adolescents with NCD living in iodine-deficient areas, and to assess their pathological and clinical significance. A cohort of 120 adolescents aged 13–17 years with clinically diagnosed NCD was examined and compared with 40 healthy peers. Trace element levels were determined using atomic absorption spectrophotometry and correlated with thyroid hormone profiles, cardiovascular function, and clinical symptoms. Results revealed a strong interdependence between iodine deficiency and alterations in the metabolism of other trace elements, particularly decreased selenium and zinc levels, which contributed to both thyroid dysfunction and autonomic imbalance. These findings highlight the importance of comprehensive micronutrient monitoring and targeted supplementation in the management of NCD in iodine-deficient populations.Keywords
