Patients with thyroid storm require urgent stabilization in critical care settings with fluids, beta blockers, antithyroid medications ( propylthiouracil, potassium iodide, and parenteral glucocorticoids), active cooling, and management of tachyarrhythmias. An acute exacerbation of thyrotoxicosis can lead to a life-threatening hypermetabolic state known as thyroid storm, which is diagnosed clinically along with thyroid function tests. Management of any form of thyrotoxicosis involves the initial control of symptoms with beta blockers and antithyroid drugs, often followed by definitive therapy with either radioactive iodine ablation ( RAIA) of the thyroid gland or surgery. Serological thyroid hormone assay confirms thyrotoxicosis, while the measurement of antithyroid antibodies, thyroid ultrasonography, and radioactive iodine uptake tests help to identify the etiology. ![]() The most common symptoms of thyrotoxicosis include fatigue, anxiety, heat intolerance, increased perspiration, palpitations, and significant weight loss despite increased appetite. In rare cases, thyrotoxicosis is caused by TSH-producing pituitary tumors (central hyperthyroidism), excessive production of β-hCG ( gestational trophoblastic disease), or oral intake of thyroid hormones ( exogenous hyperthyroidism). It may also be caused by the inappropriate release of thyroid hormone from a damaged or inflamed thyroid gland (e.g., thyroiditis). ![]() It is typically caused by thyroid gland hyperactivity (i.e., hyperthyroidism), the most common causes of which are Graves disease (most common), toxic multinodular goiter (MNG), and toxic adenoma. Thyrotoxicosis refers to the symptoms caused by the excessive circulation of thyroid hormones. ![]()
