Abstract

Grave’s disease is a hyperfunction of the thyroid gland associated with diffuse goiter due to excessive secretion of thyroid hormones into the blood, the excessive excretion of the hormones Triiodothyronin (T3) and Tetraiodthyronon (T4) too much compared to the need that create thyroidtoxicity affects many organ systems including the cardiovascular system, gastrointestinal tract... Clinically, abnormal liver function tests are often observed in untreated hyperthyroidism patients. However, the prevalence reported varied between studies, ranging from 37% to 78%. Until now, a number of factors are thought to contribute to liver dysfunction in hyperthyroidism. However, the association between indicators of thyroid function and liver damage remains controversial and data demonstrating biochemical factors or parameters contribute to liver function abnormalities due to Basedow causes are still limited.
