Iodine deficiency causes gradual enlargement of the thyroid gland, referred to as a goiter. Poor length growth is apparent as early as the first year of life. Adult stature without treatment ranges from 100 to 160 cm (3 ft 3 in to 5 ft 3 in), depending on severity, sex, and other genetic factors.
Thyroid disease is a medical condition that affects the function of the thyroid gland.The thyroid gland is located at the front of the neck and produces thyroid hormones [1] that travel through the blood to help regulate many other organs, meaning that it is an endocrine organ.
A goitre, if associated with hypothyroidism or hyperthyroidism, may be present with symptoms of the underlying disorder. For hyperthyroidism, the most common symptoms are associated with adrenergic stimulation: tachycardia (increased heart rate), palpitations, nervousness, tremor, increased blood pressure and heat intolerance.
Caleb Hillier Parry first made the association between the goiter and protrusion of the eyes in 1786, however, did not publish his findings until 1825. [57] In 1835, Irish doctor Robert James Graves discovered a link between the protrusion of the eyes and goiter, giving his name to the autoimmune disease now known as Graves' Disease. [citation ...
Hyperthyroidism (an example is Graves' disease) is the clinical syndrome caused by an excess of circulating free thyroxine, free triiodothyronine, or both. It is a common disorder that affects approximately 2% of women and 0.2% of men. Thyrotoxicosis is often used interchangeably with hyperthyroidism, but there are subtle differences.
Graves' disease occurs in about 0.5% of people. [4] Graves' disease data has shown that the lifetime risk for women is around 3% and 0.5% for men. [39] It occurs about 7.5 times more often in women than in men [1] and often starts between the ages of 40 and 60. [6]
Sub-clinical hyperthyroidism has been reported in 63% of euthyroid Graves' disease, [56] but only in 4% of cases where Graves' disease was in remission. [57] Subclinical hyperthyroidism has an 8% risk of converting to overt hyperthyroidism at 1 year, and a 26% risk at 5 years. [50]
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).
