| description | Objective: to assess the natural course of subclinical hypothyroidism in young athletes.Methods: In the prospective single-center uncontrolled study, data from 3,062 outpatient records of young athletes (members of the Russian national team) of both sexes (middle age — 15 [14; 16] years) and underwent medical examination in the period from January 2021 to September 2022 were studied. All athletes were divided into 2 groups according to the presence of subclinical hypothyroidism (an increase in the level of thyroid-stimulating hormone from 5 to 10 mUn/l with a normal level of T4 free). During a dynamic follow-up (1 year), athletes with subclinical hypothyroidism underwent a repeated study of the concentration of thyroid-stimulating hormone, free thyroxine and antibodies to thyroperoxidase.Results: Signs of subclinical hyperthyroidism were found in 58 young athletes (30 boys (51.7 %) and 28 (48.3 %) girls). During dynamic observation with continued habitual physical activity, spontaneous normalization of the level of thyroid-stimulating hormone was observed in 74 % of young athletes. At the same time, normalization of thyroid-stimulating hormone in girls was observed less often compared to boys (p = 0,272). In no case did clinically pronounced hypothyroidism develop.Conclusion: The majority of young male and female athletes with subclinical hypothyroidism have spontaneous normalization of hormonal profile against the background of persistent physical and psycho-emotional stress. The data obtained make it possible, subject to the possibility of dynamic observation, to recommend doctors working with young elite athletes not to prescribe hormonal replacement therapy and not to modify the usual lifestyle. |
