Crisis in uncontrolled hyperthyroidism in which the release of thyroid hormone into the bloodstream causes rapid pulse, fever, respiratory distress, and restlessness, leading to delirium, heart failure, and death. Treatment is by antithyroid drugs.
A rare but often life threatening medical emergency resulting from untreated hyperthyroidism. It is marked by fevers, sweating, restlessness, irritability, tachycardia, hypertension, heart failure, shock, and cardiac arrhythmias, delirium, and coma, among other findings. It may begin when a patient with hyperthyroidism suffers a second illness (e.g., an infection), after thyroid gland surgery, or after withdrawal from antithyroid drug treatment.
An uncommon yet potentially life-threatening complication of hyperthyroidism, distinguished by a high fever surpassing 104.8°F, irregular heart rhythm, vomiting, diarrhea, dehydration, coma, and ultimately, fatality.
