<prompt> Disorder associated with thyrotoxicosis but not associated with hypehyroidism is:Graves diseaseHyperfunctioning toxic multinodular goiterIodine-induced hypehyroidismDe Quervain thyroiditis  <response>: Thyrotoxicosis is a hypermetabolic state caused by elevated circulating levels of free T3 and T4 . most commonly caused by hyperfunctioning of thyroid gland, therefore it is often referred as hypehyroidism. However, in ceain conditions the oversupply is related to either excessive release of preformed thyroid hormone e.g., in thyroiditis or to an extrathyroidal source, rather than hyperfunctioning of gland.
