Thyroid storm
Thyroid Storm[edit | edit source]
Thyroid storm, also known as thyrotoxic crisis, is a rare but life-threatening condition characterized by an extreme overproduction of thyroid hormones. It is a severe form of hyperthyroidism and requires immediate medical attention.
Pathophysiology[edit | edit source]
Thyroid storm occurs when there is a sudden and excessive release of thyroid hormones, leading to a hypermetabolic state. This can result from untreated or inadequately treated Graves' disease, toxic multinodular goiter, or thyroiditis. The excessive thyroid hormones increase the body's metabolism, affecting multiple organ systems.
Symptoms[edit | edit source]
The symptoms of thyroid storm are severe and can include:
- High fever
- Tachycardia (rapid heart rate)
- Hypertension (high blood pressure)
- Arrhythmias
- Heart failure
- Delirium or psychosis
- Nausea, vomiting, and diarrhea
- Jaundice
Diagnosis[edit | edit source]
Diagnosis of thyroid storm is primarily clinical, based on the presence of symptoms and a history of hyperthyroidism. Laboratory tests may show elevated levels of triiodothyronine (T3) and thyroxine (T4), with suppressed thyroid-stimulating hormone (TSH).
Treatment[edit | edit source]
Treatment of thyroid storm involves:
- Antithyroid medications: Such as propylthiouracil or methimazole to reduce thyroid hormone production.
- Beta-blockers: To control symptoms like tachycardia and hypertension.
- Corticosteroids: To reduce inflammation and inhibit peripheral conversion of T4 to T3.
- Supportive care: Including intravenous fluids, oxygen therapy, and cooling blankets to manage fever.
Prognosis[edit | edit source]
With prompt and appropriate treatment, the prognosis for thyroid storm can be good. However, if left untreated, it can lead to severe complications such as heart failure, shock, and death.
Prevention[edit | edit source]
Preventing thyroid storm involves proper management of underlying hyperthyroidism. Regular monitoring and adherence to prescribed treatments can help prevent the occurrence of a thyroid storm.
