thyrotoxicosis

 [thi″ro-tok″sĭ-ko´sis]
the condition caused by excessive quantities of thyroid hormones (see hyperthyroidism); it may be due to overproduction by the thyroid gland (as in Graves' disease), overproduction originating outside the thyroid, or loss of storage function and leakage from the gland.

thy·ro·tox·i·co·sis

(thī'rō-tok'si-kō'sis),
The state produced by excessive quantities of endogenous or exogenous thyroid hormone.

thyrotoxicosis

Cardiovascular disease High-output heart failure due to
1. Circulatory factors–↑ total blood volume, ↓ systemic vascular resistance,.
2. Cardiac factors–↑ contractility, ↑ heart rate, ↑ diastolic relaxation, which translate into volume overload, ↓ myocardial contractile reserve, ↓ diastolic filling time, tachyarrhythmia Management Inorganic iodine abruptly inhibits T3 and T4 secretion, but should be preceded by methimazole or propyluracil to prevent oxidation and organification of iodine, followed by definitive treatment of 1. Thyrotoxicosis–radioactive iodine, surgical resection, 2. Heart disease–eg, furosemide–diuretic for volume overload, beta blockers–eg, propranolol, in absence of CHF, and anticoagulants for possible arterial thromboembolism due to A Fib.

thyrotoxicosis

The disorder resulting from excessive production of thyroid hormones, so that all cellular metabolic processes are accelerated. Thyrotoxicosis is much commoner in women than in men. The majority of cases are of AUTOIMMUNE origin. There is loss of weight, good appetite, a fast, irregular pulse, anxiety, inability to relax, shakiness, palpitation, sweating and dislike of hot weather and frequent bowel actions. Retraction of the upper eyelids causes a staring appearance and the eyes may protrude (EXOPHTHALMOS) from swelling of the tissues behind them. Treatment is with drugs, such as carbimazole, methimazole and thiouracil, which reduce the activity of the gland, by the use of radioactive iodine which concentrates in the gland or by surgical removal of part of the gland (partial THYROIDECTOMY).

Thyrotoxicosis

An excess of thyroid hormones in the blood, causing a variety of symptoms that include rapid heart beat, sweating, anxiety, and tremor.

hyperthyroidism

; thyrotoxicosis high blood levels of thyroxine due to intrinsic thyroid disease (e.g. autoimmune or inflammatory disease; benign thyroid tumour); more common in women than men (5:1 ratio); characterized by irritability, hyperkinesis and tremor, warm vasodilated extremities with palmar and plantar erythema, exophthalmos and lid lag, goitre, pretibial myxoedema, onycholysis, proximal myopathy, weight loss, atrial fibrillation and tachycardia; treated by thyroid radioablation, antithyroid drugs (e.g. carbimazole) and/or thyroidectomy
