Hypothyroidism is common in pregnancy with an estimated prevalence of 2-3% and 0.3-0.5% for subclinical and overt hypothyroidism respectively. [8] Endemic iodine deficiency accounts for most hypothyroidism in pregnant women worldwide while chronic autoimmune thyroiditis is the most common cause of hypothyroidism in iodine sufficient parts of the world.
Hyperthyroidism due to certain types of thyroiditis can eventually lead to hypothyroidism (a lack of thyroid hormone), as the thyroid gland is damaged. Also, radioiodine treatment of Graves' disease often eventually leads to hypothyroidism. Such hypothyroidism may be diagnosed with thyroid hormone testing and treated by oral thyroid hormone ...
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.
Graves' disease is an autoimmune disorder that is the most common cause of hyperthyroidism. [58] In Graves' disease, for an unknown reason autoantibodies develop against the thyroid stimulating hormone receptor. These antibodies activate the receptor, leading to development of a goitre and symptoms of hyperthyroidism, such as heat intolerance ...
Sub-clinical hyperthyroidism has been reported in 63% of euthyroid Graves' disease, [56] but only in 4% of cases where Graves' disease was in remission. [57] Subclinical hyperthyroidism has an 8% risk of converting to overt hyperthyroidism at 1 year, and a 26% risk at 5 years. [50]
Thyroid hormones act on nearly every cell in the body. They act to increase the basal metabolic rate, affect protein synthesis, help regulate long bone growth (synergy with growth hormone) and neural maturation, and increase the body's sensitivity to catecholamines (such as adrenaline) by permissiveness. [12]
Graves' disease, also known as toxic ... (the cells that produce thyroid hormone), and the result of chronic stimulation is an abnormally high production of T3 and T4 ...
2.The Hfr cell forms sex pili a pilus and attaches to a recipient F- cell. 3.A nick in one strand of the Hfr cell’s chromosome is created. 4.DNA begins to be transferred from the Hfr cell to the recipient cell while the second strand of its chromosome is being replicated. 5.The pilus detaches from the recipient cell and retracts.
