Hyperthyroidism is a condition in which the thyroid gland produces too much of the hormone thyroxine (T4). Thyroid gland is a butter-fly shaped endocrine gland found in the front of the neck below the larynx and has two lobes, one on each side of the windpipe. Thyroid gland produces two main hormones, thyroxine (T4) and triiodothyronine (T3). The hypothalamus signals of pituitary gland to make a hormone called thyroid-stimulating hormone (TSH). Finally thyroid gland regulates its production of hormones based on the amount of TSH it receives. The thyroid gland has an enormous impact on your health. Every aspect of the body metabolism is regulated by thyroid hormones. Hyperthyroidism also known as “Overactive thyroid”.
