The thyroid gland is located in front of the windpipe (windpipe) in your neck. The gland is divided into 2 lobes (right and left) and is connected in the middle with a thin thyroid gland bridge called the isthmus. Due to the two connected lobes, the thyroid was described as having the shape of a butterfly or bow tie. The thyroid cartilage, which is the largest laryngeal cartilage (the voice box), lies just above the thyroid gland and is sometimes known as Adam’s apple. Normal thyroid size cannot be seen in the neck and you can barely feel it. Only when certain conditions lead to the enlargement of the thyroid (known as the will), can you notice or feel the bulge just under Adam’s apple?
Thyroid hormones functions
The thyroid is part of the body’s endocrine system. The organs of the endocrine system secrete hormones. The primary function of the thyroid gland is the secretion of thyroid hormones. Thyroid hormones take part in the regulation of many body functions, such as breathing, heart rate, temperature, calorie burning, and digestion, as well as many other functions. Infants and children need adequate amounts of thyroid hormones for brain development and development.
Your thyroid needs iodine (a chemical element that is an essential part of our diet) to produce these thyroid hormones. Foods that are naturally rich in iodine include seafood and plants grown on iodine-rich soil. Iodised salt is another good source of iodine diet. The two primary thyroid hormones are T3 (triiodothyronine) and T4 (thyroxine). T3 and T4 regulate body temperature, metabolism, and heart rate.
The number of secreted thyroid hormone is controlled by an additional hormone, called thyroid stimulating hormone (TSH), which is released from the pituitary gland in the brain. TSH stimulates the thyroid to build T3 and T4. Blood tests are performed on the level of TSH when doctors are examining thyroid disease. T3 and T4 tests can also be tested. Please note that different laboratories may have different reference ranges for normal, so always follow the doctor’s instructions.
T3 or triiodothyronine
T3 tests can help diagnose hyperthyroidism (hyperthyroidism). Usually accepted normal range for free T3 (which measures T3 in the bloodstream, but not T3 bound to the protein in your body) is between 3.1 pmol / L and 6.8 pmol / L.
The normal range usually cited for free thyroxine (T4) is 12-22 pmol / L. In people with hyperthyroidism (hyperthyroidism), free T4 usually exceeds 22 pmol / L. And for those with hypothyroidism (hypothyroidism), free T4 is usually below 12 pmol / L.
Symptoms of hyperthyroidism
Hyperthyroidism in which hyperthyroidism can lead to such symptoms as weight loss, rapid pulse, being too hot, nervousness or nervousness and irregular menstruation.
