A thyroid crisis, also known as thyroid storm, is a rare but severe condition that occurs when there is an extreme overproduction of thyroid hormones in the body. This can lead to symptoms such as rapid heart rate, high fever, and confusion. It often arises in individuals with untreated hyperthyroidism or those who have had recent surgery or illness. Immediate medical attention is crucial for a thyroid crisis, as it can be life-threatening. Treatment typically involves medications to lower thyroid hormone levels, manage symptoms, and address any underlying causes. Early recognition and intervention can significantly improve outcomes for affected individuals.
