Objective: Introduction: Chronic diseases of the upper respiratory tract in children and teenagers, such as chronic tonsillitis is quite common in pediatric populations, accompanied by changes in reactivity, causing a risk of complications. Due to the fact that the child's body resistance to acute infectious diseases depends on the sufficiency of trace elements, then at present stage greatly increased interest in deeper study of exchange of macro- and microelements in the human body in normal and pathological conditions. The aim: To study the dynamics of zinc, iron, potassium and magnesium in adolescents with disorders of the cardiovascular system with chronic tonsillitis.
