Compare and contrast levels of thyroid hormones and TSH in Graves disease versus Hashimoto ...

Both conditions are autoimmune disease of the thyroid. Graves disease is the most common cause of hyperthyroidism; it is an autoimmune thyroid disease in which the autoantibodies resemble TSH stimulate the TSH receptors causing overproduction of thyroid hormones; results in hyperthyroidism in which both T3 and T4 levels are increased in the blood but with a reduced level of TSH Hashimoto thyroiditis is the most common cause of hypothyroidism in adults, especially middle-aged women; thyroid autoantibodies are directed against the TSH receptors and activated lymphocytes directed at the thyroid attack the gland and destroy it; results in hypothyroidism in which T3 and T4 levels are reduced but with an increased level of TSH in the blood.
