What is thyroid storm?

Thyroid storm is a life-threatening emergency that arises from untreated or poorly managed hyperthyroidism. This condition is characterized by a massive release of thyroid hormones into the bloodstream, often triggered by stressors such as infection, surgery, or trauma. The excessive levels of these hormones lead to a hypermetabolic state, resulting in profound physiological effects, including increased heart rate, elevated blood pressure, fever, agitation, and potentially multi-organ failure.

Recognizing thyroid storm is crucial since it requires immediate medical intervention to prevent serious complications or death. Treatment typically includes antithyroid medications to reduce hormone production, beta-blockers to manage symptoms like rapid heart rate, and supportive care.

In contrast, the other options do not accurately describe thyroid storm. Sudden weight gain relates to hypothyroidism rather than hyperthyroidism, while an increase in thyroid hormone production is a hallmark of hyperthyroidism but does not encompass the critical and acute nature of a thyroid storm. Additionally, a mild form of hyperthyroidism does not capture the severity and urgency of thyroid storm, which entails a severe and rapid exacerbation of hyperthyroid symptoms.
