A thyroid storm is a rare but life-threatening condition that occurs when the body produces an excessive amount of thyroid hormones. This can happen in people with untreated or poorly managed hyperthyroidism, a condition where the thyroid gland is overactive. Symptoms of a thyroid storm include a rapid heartbeat, high fever, sweating, and confusion. It requires immediate medical attention to prevent serious complications. The condition can be triggered by factors such as stress, infection, or surgery. Treatment typically involves medications to lower thyroid hormone levels and manage symptoms. If not treated quickly, a thyroid storm can lead to severe health issues, including heart failure or coma.
