Introduction
Hyperthyroidism is defined as a condition where excess of thyroid hormones are produced by the thyroid gland. The term ‘Thyrotoxicosis’ refers to an excess of thyroid hormones in the blood.
As the name suggests, there is excess of thyroid hormones (T3- thyroxine and T4 -triiodothyronine) that are responsible for metabolism in our body and help maintain the overall BMR. Thus, an excess of these hormones speeds up the metabolism and exacerbates the sympathetic nervous system and results in symptoms resembling an adrenaline rush! | |
