Hormone secreted thyroid gland also plays a role in normal development of organs such as the heart and brain, as well as for normal reproductive function. The right amount of hormone production is also important for bone and calcium metabolism.
Hormone produced by the thyroid gland is thyroxine (T4) and tri-iodothyronine (T3). Both levels of this hormone are too high or too low can cause serious health problems.
examination
Level or known thyroid levels through a simple blood test by your doctor. Test results will indicate whether the production of hormones by the thyroid gland is normal, overactive, or underactive.
What is Detected by Examination?
In order to perform its function of thyroid gland, the hypothalamus must release thyrotropin-releasing hormone (TRH). TRH then triggers the pituitary gland to produce thyroid-stimulating hormone (TSH).
TSH stimulates the thyroid gland to make T3 and T4. To determine whether the thyroid functioning properly, blood tests will check TSH levels.
Normal levels of
In adults, normal TSH level is 0.4 to 4.5 mIU / L. Whereas in infants, normal levels of TSH was 3-18 mIU / L.
mIU / L stands for milli-international units per liter. TSH levels that are beyond the range classified as hypothyroidism or hyperthyroidism.
Hyperthyroidism (hyperthyroidism)
Hyperthyroidism occurs when there is excess production of thyroid hormone. Symptoms of this condition include muscle weakness, trembling, fatigue, rapid heart rate, weight loss, sensitive to temperature problems, and vision problems.
Hypothyroidism (Hypothyroidism)
The condition was diagnosed hypothyroidism when thyroid hormone production is lower than normal levels. Symptoms of hypothyroidism include fatigue, weight gain, feeling cold and lethargic, dry skin and hair, as well as constipation.
