Graves disease develops in about 0.5% of males and 3.0% of females. [5] It occurs about 7.5 times more often in women than in men. [1] Often, it starts between the ages of 40 and 60, but can begin at any age. [6] It is the most common cause of hyperthyroidism in the United States (about 50 to 80% of cases).
The disease has become significantly more common since the first reports of feline hyperthyroidism in the 1970s. The most common cause of hyperthyroidism in cats is the presence of benign tumors called adenomas. 98% of cases are caused by the presence of an adenoma, [64] but the reason these cats develop such tumors continues to be studied.
It is the most common cause of hypothyroidism in areas of sufficient iodine. [10] Also, the rate of lymphocytic infiltration increased in areas where the iodine intake was once low, but increased due to iodine supplementation. [27] [118] Iodine deficiency disorder is combated using an increase in iodine in a person's diet. When a dramatic ...
Graves' disease is an autoimmune disorder that is the most common cause of hyperthyroidism. [58] In Graves' disease, for an unknown reason autoantibodies develop against the thyroid stimulating hormone receptor. These antibodies activate the receptor, leading to development of a goitre and symptoms of hyperthyroidism, such as heat intolerance ...
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).
Around the world, the most common cause of congenital iodine deficiency syndrome (endemic cretinism) [1] is dietary iodine deficiency. Iodine is an essential trace element, necessary for the synthesis of thyroid hormones. Iodine deficiency is the most common preventable cause of neonatal and childhood brain damage worldwide. [11]
In areas where iodine-deficiency is not found, the most common type of hypothyroidism is an autoimmune subtype called Hashimoto's thyroiditis, with a prevalence of 1-2%. [40] As for hyperthyroidism, Graves' disease, another autoimmune condition, is the most common type with a prevalence of 0.5% in males and 3% in females. [41]
Some do so only a few months after treatment while others may not be affected for 20–30 years. Hypothyroidism patients must begin a lifelong regimen of thyroid replacement hormones. While the onset of hypothyroidism is most common with radio-iodine treatment, the condition has been observed in patients treated with medication series and surgery.
