A low amount of thyroxine (one of the two thyroid hormones) in the blood, due to lack of dietary iodine to make it, gives rise to high levels of thyroid stimulating hormone (TSH), which stimulates the thyroid gland to increase many biochemical processes; the cellular growth and proliferation can result in the characteristic swelling or hyperplasia of the thyroid gland, or goiter.
Iodine deficiency, Hashimoto's thyroiditis [3] Diagnostic method: Blood tests (thyroid-stimulating hormone, thyroxine) [3] Differential diagnosis: Depression, dementia, heart failure, chronic fatigue syndrome [6] Prevention: Salt iodization [7] Treatment: Levothyroxine [3] Frequency: 5% (USA) [8]
A deficiency of iodine leads to decreased production of T 3 and T 4 and a concomitant enlargement of the thyroid tissue in an attempt to obtain more iodine, causing the disease goitre. The major form of thyroid hormone in the blood is tetraiodothyronine (T 4), which has a longer life than triiodothyronine (T 3).
Congenital iodine deficiency has been almost eliminated in developed countries through iodine supplementation of food and by newborn screening utilizing a blood test for thyroid function. [5] Treatment consists of lifelong administration of thyroxine (T4). Thyroxine must be dosed as tablets only, even to newborns, as the liquid oral suspensions ...
Initial blood tests often include thyroid-stimulating hormone (TSH) and free thyroxine (T4). [9] Total and free triiodothyronine (T3) levels are less commonly used. [9] If autoimmune disease of the thyroid is suspected, blood tests looking for Anti-thyroid autoantibodies can also be obtained. Procedures such as ultrasound, biopsy and a ...
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 will cause the disease known as simple goitre. [3] The major form of thyroid hormone in the blood is thyroxine (T 4), whose half-life of around one week [4] is longer than that ...
