  2. Hypothyroidism - Wikipedia

    en.wikipedia.org/wiki/Hypothyroidism

    Subclinical hypothyroidism is a biochemical diagnosis characterized by an elevated serum TSH level, but with a normal serum free thyroxine level. [48] [49] [50] The incidence of subclinical hypothyroidism is estimated to be 3-15% and a higher incidence is seen in elderly people, females and those with lower iodine levels. [48]

  3. Thyroid disease - Wikipedia

    en.wikipedia.org/wiki/Thyroid_disease

    Certain medications can have the unintended side effect of affecting thyroid function. While some medications can lead to significant hypothyroidism or hyperthyroidism and those at risk will need to be carefully monitored, some medications may affect thyroid hormone lab tests without causing any symptoms or clinical changes, and may not require treatment.

  4. Jostel's TSH index - Wikipedia

    en.wikipedia.org/wiki/Jostel's_TSH_index

    It is unclear if this finding reflects shortcomings of the index (i.e. low specificity in the setting of subclinical hypothyroidism) or plastic responses of the pituitary gland to beginning hypothyroidism. [citation needed] In subjects with type 2 diabetes, treatment with beta blockers resulted in increased TSH index, but the mechanism is ...

    Levothyroxine, a drug used to treat hypothyroidism, can lead to reduced bone mass and density in older adults with normal thyroid levels, a small cohort study has shown.

  6. Thyroid function tests - Wikipedia

    en.wikipedia.org/wiki/Thyroid_function_tests

    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.

  7. Levothyroxine - Wikipedia

    en.wikipedia.org/wiki/Levothyroxine

    Levothyroxine is also used to treat subclinical hypothyroidism, which is defined by an elevated TSH level and a normal-range free T 4 level without symptoms. [14] Such people may be asymptomatic [14] and whether they should be treated is controversial. [13]

  8. Thyroid-stimulating hormone - Wikipedia

    en.wikipedia.org/wiki/Thyroid-stimulating_hormone

    Thyroid-stimulating hormone (also known as thyrotropin, thyrotropic hormone, or abbreviated TSH) is a pituitary hormone that stimulates the thyroid gland to produce thyroxine (T 4), and then triiodothyronine (T 3) which stimulates the metabolism of almost every tissue in the body. [1]

  9. Hashimoto's thyroiditis - Wikipedia

    en.wikipedia.org/wiki/Hashimoto's_thyroiditis

    As the free amount reflects the amount available to body tissues, the most treatment-relevant measures for thyroid disorders are Free T 3 and Free T 4. [64] Typically, Free T 4 is the preferred test for hypothyroidism, [ 65 ] as Free T 3 immunoassay tests are less reliable at detecting low levels of thyroid hormone, [ 66 ] and they are more ...
