Überfunktion der Schilddrüse (Hyperthyreose)

Hyperthyroidism is a condition in which the thyroid gland produces excessive amounts of the thyroid hormones (T3 and T4).

Latent hyperthyroidism

Latent hyperthyroidism is discovered through laboratory testing which shows, at the same time, reduced TSH and normal T3 and T4 levels. With latent hyperthyroidism, the symptoms or complaints are minimal.
