Video - Thyroid storm

Thyroid storm, also known as a thyrotoxic crisis, is a rare but life-threatening medical emergency caused by a sudden and severe worsening of hyperthyroidism (overactive thyroid). It is more common in individuals with untreated or poorly controlled hyperthyroidism and may be triggered by stress, infection, surgery, or other medical conditions.

Signs and symptoms include high fever, tachycardia, high blood pressure, agitation, confusion, sweating, vomiting, diarrhea, and in severe cases, seizures or coma. It can be fatal if left untreated, and prompt medical attention is necessary. The treatment involves medications like β-blockers, propylthiouracil, corticosteroids, and potassium iodide.
