Thyroxine or tetraiodothyronine (T4) is produced by the thyroid gland. The term is sometimes used to refer to hyperthyroidism, but hyperthyroidism is a more general term. [2] When the level of thyroxine (T4) in the blood exceeds normal range, it can lead to symptoms such as irritability and unexplained weight loss. [3] Types include:
Less commonly, a single nodule is responsible for the excess hormone secretion, called a "hot" nodule. Thyroiditis (inflammation of the thyroid) can also cause hyperthyroidism. [24] Functional thyroid tissue producing an excess of thyroid hormone occurs in a number of clinical conditions. The major causes in humans are: Graves' disease. An ...
According to Chang, other possible causes of hyperthyroidism include: thyroiditis (thyroid inflammation), thyroid nodules (which produce more thyroid hormone), and consuming an excess amount of ...
Toxic multinodular goiter (TMNG), also known as multinodular toxic goiter (MNTG), is an active multinodular goiter associated with hyperthyroidism.. It is a common cause of hyperthyroidism [2] [3] in which there is excess production of thyroid hormones from functionally autonomous thyroid nodules, which do not require stimulation from thyroid stimulating hormone (TSH).
The most useful marker of thyroid gland function is serum thyroid-stimulating hormone (TSH) levels. TSH levels are determined by a classic negative feedback system in which high levels of T3 and T4 suppress the production of TSH, and low levels of T3 and T4 increase the production of TSH. TSH levels are thus often used by doctors as a screening ...
To understand how high levels of thyroxine can be toxic and lead to thyrotoxic myopathy physiologically, consider basic neuromuscular junction function. Under normal circumstances, muscle contraction occurs when electrical impulses travel down descending axons from the brain or spinal cord towards the neuromuscular junction .
Thyroid function tests (TFTs) is a collective term for blood tests used to check the function of the thyroid. [1] TFTs may be requested if a patient is thought to suffer from hyperthyroidism (overactive thyroid) or hypothyroidism (underactive thyroid), or to monitor the effectiveness of either thyroid-suppression or hormone replacement therapy.
The abnormality in the channel is thought to lead to shifts of potassium into cells, under conditions of high thyroxine (thyroid hormone) levels, usually with an additional precipitant. Treatment of the low levels of potassium in the blood, followed by correction of the hyperthyroidism, leads to complete resolution of the attacks.
