The majority of cases occur in women over 60 years of age, although it may happen in all age groups. [19] Most hypothyroidism is primary in nature. Central/secondary hypothyroidism affects 1:20,000 to 1:80,000 of the population or about one out of every thousand people with hypothyroidism. [10]
The pituitary gland secretes thyrotropin (TSH; Thyroid Stimulating Hormone) that stimulates the thyroid to secrete thyroxine (T4) and, to a lesser degree, triiodothyronine (T3). The major portion of T3, however, is produced in peripheral organs, e.g. liver, adipose tissue, glia and skeletal muscle by deiodination from circulating T4.
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 National Academy of Clinical Biochemistry (NACB) stated that it expected the reference range for adults to be reduced to 0.4–2.5 μIU/mL, because research had shown that adults with an initially measured TSH level of over 2.0 μIU/mL had "an increased odds ratio of developing hypothyroidism over the [following] 20 years, especially if ...
Thyroid cancer affects tens of thousands of people per year, and the majority are women. Of the 44,000 people who will likely be diagnosed with thyroid cancer this year, more than 31,000 will be ...
It has been shown that the prevalence of positive tests for thyroid antibodies increases with age, "with a frequency as high as 33 percent in women 70 years old or older." [ 27 ] Hashimoto's thyroiditis can occur at any age, including children, [ 119 ] but more commonly appears in middle age , particularly for men. [ 123 ]
The TSH index is reduced in patients with secondary hypothyroidism resulting from thyrotropic insufficiency. [1] [9] [10] [11] For this indication, it has, however, up to now only been validated in adults. [12] JTI was also found reduced in cases of TACITUS syndrome (non-thyroidal illness syndrome) as an example of type 1 thyroid allostasis.
Thyroid disease is a medical condition that affects the structure and/or 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.
