Triiodothyronine, also known as T3, is a thyroid hormone. It affects almost every physiological process in the body, including growth and development, metabolism, body temperature, and heart rate.
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. It is also requested routinely in conditions ...
Thyroid hormones are any hormones produced and released by the thyroid gland, namely triiodothyronine ( T3) and thyroxine ( T4 ). They are tyrosine -based hormones that are primarily responsible for regulation of metabolism. T 3 and T 4 are partially composed of iodine, derived from food. [2] A deficiency of iodine leads to decreased production of T 3 and T 4, enlarges the thyroid tissue and ...
A new study finds that intermittent fasting with low-calorie meal replacements may be an effective way for people with type 2 diabetes to lose weight and control blood sugar levels, compared to ...
Reverse triiodothyronine (3,3′,5′-triiodothyronine, reverse T 3, or rT 3) is an isomer of triiodothyronine (3,5,3′ triiodothyronine, T 3 ). Reverse T 3 is the third-most common iodothyronine the thyroid gland releases into the bloodstream, at 0.9%; tetraiodothyronine (levothyroxine, T 4) constitutes 90% and T 3 is 9%.
Wilson's ( temperature) syndrome, also called Wilson's thyroid syndrome or WTS, is a term used in alternative medicine to improperly attribute various common and non-specific symptoms to abnormally low body temperature and impaired conversion of thyroxine (T4) to triiodothyronine (T3), despite normal thyroid function tests. [1] E. Denis Wilson, a physician who invented the concept and named it ...
Intermittent fasting. Intermittent fasting is any of various meal timing schedules that cycle between voluntary fasting (or reduced calorie intake) and non-fasting over a given period. [1] [2] Methods of intermittent fasting include alternate-day fasting, [3] periodic fasting, such as the 5:2 diet, and daily time-restricted eating.
Impaired fasting glucose is a type of prediabetes, in which a person's blood sugar levels during fasting are consistently above the normal range, but below the diagnostic cut-off for a formal diagnosis of diabetes mellitus. [2] Together with impaired glucose tolerance, it is a sign of insulin resistance. In this manner, it is also one of the conditions associated with metabolic syndrome .
