  2. Thyroid-stimulating hormone - Wikipedia

    en.wikipedia.org/wiki/Thyroid-stimulating_hormone

    The therapeutic target range TSH level for patients on treatment ranges between 0.3 and 3.0 μIU/mL. [18] For hypothyroid patients on thyroxine, measurement of TSH alone is generally considered sufficient. An increase in TSH above the normal range indicates under-replacement or poor compliance with therapy.

  3. 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.

  4. Thyroid hormones - Wikipedia

    en.wikipedia.org/wiki/Thyroid_hormones

    Thyroid tablets are reported to have different effects, which can be attributed to the difference in torsional angles surrounding the reactive site of the molecule. [ 14 ] Thyronamines have no medical usages yet, though their use has been proposed for controlled induction of hypothermia , which causes the brain to enter a protective cycle ...

  5. Thyroid - Wikipedia

    en.wikipedia.org/wiki/Thyroid

    TSH release in turn is stimulated by thyrotropin releasing hormone (TRH), released in a pulsatile manner from the hypothalamus. [39] The thyroid hormones provide negative feedback to the thyrotropes TSH and TRH: when the thyroid hormones are high, TSH production is suppressed. This negative feedback also occurs when levels of TSH are high ...

  6. Reflex - Wikipedia

    en.wikipedia.org/wiki/Reflex

    In biology, a reflex, or reflex action, is an involuntary, unplanned sequence or action [1] and nearly instantaneous response to a stimulus. [2] [3] The simplest reflex is initiated by a stimulus, which activates an afferent nerve. The signal is then passed to a response neuron, which generates a response.

  7. Hypothalamic–pituitary–thyroid axis - Wikipedia

    en.wikipedia.org/wiki/Hypothalamic–pituitary...

    The TSH, in turn, stimulates the thyroid to produce thyroid hormone until levels in the blood return to normal. Thyroid hormone exerts negative feedback control over the hypothalamus as well as anterior pituitary, thus controlling the release of both TRH from hypothalamus and TSH from anterior pituitary gland.

  8. Hypothyroidism - Wikipedia

    en.wikipedia.org/wiki/Hypothyroidism

    In pregnancy, subclinical hypothyroidism is defined as a TSH between 2.5 and 10 mIU/L with a normal thyroxine level, while those with TSH above 10 mIU/L are considered to be overtly hypothyroid even if the thyroxine level is normal. [44]

  9. Thyroid disease - Wikipedia

    en.wikipedia.org/wiki/Thyroid_disease

    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.
