Thyroid hormone requirements increase during and last throughout pregnancy. [14] As such, pregnant women are recommended to increase to nine doses of levothyroxine each week, rather than the usual seven, as soon as their pregnancy is confirmed. [14] Repeat thyroid function tests should be done five weeks after the dosage is increased. [14]
The plasma half-life is one hour and is not altered appreciably by the thyroid status of the patient. Due to the concentration in the thyroid, however, dosing intervals may last 8 hours or longer. Less than 10% of the drug is excreted unchanged, with the remaining fraction undergoing extensive hepatic metabolism via glucuronidation.
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.
The thyroid system of the thyroid hormones T 3 and T 4 [1] Thyroid hormones are two hormones produced and released by the thyroid gland, triiodothyronine (T 3) and thyroxine (T 4). 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]
The gland increases in size by 10%, thyroxine production increases by 50%, and iodine requirements increase. Many women have normal thyroid function but have immunological evidence of thyroid autoimmunity (as evidenced by autoantibodies) or are iodine deficient, and develop evidence of hypothyroidism before or after giving birth.

Women with Hashimoto's disease or an underactive thyroid who are taking levothyroxine before pregnancy may need a higher dose to maintain normal thyroid function. Clinicians may check thyroid function every 6 to 8 weeks during pregnancy. After delivery, hormone levels usually go back to the pre-pregnancy level. [1]
Statins are generally recommended for adults between the ages of 40 and 75 who have heart disease risk factors. Despite having higher risks for cardiovascular disease, fewer older adults use statins.
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. These hormones normally act in the body to regulate energy use ...
