Document Summary
Any disease characterized by plasma concentrations of t3. Most cases are due to defects resulting from damage to or loss of functional thyroid tissue or from inadequate iodine consumption. Iodine deficiency: t3 synthesis is compromised leading to a decrease i the plasma concentration of this hormone releasing negative feedback on the hypothalamus and anterior pituitary. Trh concentrations become increased and leads to the anterior pituitary. Plasma tsh concentration becomes increased due to increased. Trh and loss of thyroid hormone negative feedback on apg. The overstimulation of the thyroid gland produces goiter s. This can be reversed if iodine is added to the diet. Most common of hypothyroidism is autoimmune thyroiditis/ hasbimoto disease which the cells of the immune system attacks and destroy the thyroid tissue. As the thyroid hormone decreases because of destruction of the thyroid tissue, tsh concentrations increase due to the decreased negative feedback. The overstimulation of the thyroid gland results in cellular hypertrophy and development of groiter.
