This gland is responsible for the synthesis of tetraiodothyronine (T4) and triiodothyronine (T3), which are the main hormone which controls the body cells to utilize energy. The primary function of thyroid gland is to regulate metabolism via the release of these thyroid hormones in the body. During overactive thyroid state excess or T3, T4 or both occur. Diagnosis and treatment of an underlying cause can help in getting relief from symptoms and further preventing the deterioration of the condition.
