Hypothyroidism and Subclinical Hypothyroidism as a Consequence of COVID-19 Infection.

Background: Hypothyroidism occurs as a consequence of chronic autoimmune inflammation of the thyroid gland, which occurs due to the reduced function in the secretion of hormones FT3 and FT4 and requires replacement therapy for life. CoV-19 infection has shown many complications in all organic systems, during the acute phase of infection and in the post COVID period.

Objectives: The aim of the study was a) to compare the frequency of patient visits for hypothyroidism and the average dose of levothyroxine in the SANASA polyclinic in the year before COVID pandemic, in the early 2019, with the frequency of patient visits during COVID infection in 2020 and 2021; b) to determine the incidence of hypothyroidism after the COVID 19 infection, the time of onset of hypothyroidism after acute phase of the disease, and the average dose of levothyroxine; and c) to monitor the incidence of subclinical hypothyroidism, which did not require substitution, before and after COVID 19 infection.
