TSH (Thyroid Stimulating Hormone): T3 and T4 hormones are secretory hormones of the thyroid gland. However, the release of these hormones is stimulated or slowed down by TSH, a regulatory hormone from the pituitary gland. Depending on the adequacy or excess of thyroid hormones in the blood, it rises and forces the thyroid gland to secrete more hormones, or it falls, preventing the thyroid gland from secreting more hormones. When it rises, it should be mutually evaluated with the state of other hormones.
FT3 (Free T3, Free T3): T3 (Triiodothyronine) is a hormone secreted by the thyroid glands. Together with the hormone T4 (Tetraiodothyroxine), it regulates many metabolic functions of the body, such as binding proteins, other proteins, enzymes, mineral and vitamin metabolism, hormonal signals, growth. After the T3 hormone is secreted from the thyroid gland, it is separated from the albumin it binds to and returns to its free state, which is active in the blood. Therefore, it is more accurate to test its active state. Its deficiency is hypothyroidism, its excess is hyperthyroidism. Hypothyroid patients are sluggish, overweight, and have a slow metabolism. Hyperthyroid patients, on the other hand, cannot gain weight; they sweat, are irritable, and are hypertensive. Thyroid disease can be seen genetically; however, there are also immunological types related to toxic and iodine intake. If it is noticed and treated without the occurrence of apparent symptoms, a life without problem can be maintained with treatment.
