Thyroid storm (thyroid crisis) is a potentially life-threatening condition for people who have hyperthyroidism . Thyroid storm happens when your thyroid gland suddenly releases large amounts of thyroid hormone in a short period of time. If you have thyroid storm, you will need emergency medical treatment.
Thyroid storm is more likely to develop when a person has a serious health problem in addition to hyperthyroidism or in people who have untreated or undertreated Graves' disease . The problem usually happens after a stressful event or a serious illness, such as a major infection. It may also be triggered by surgery or by using iodine for a CT scan or in radioactive iodine therapy.
Symptoms of thyroid storm include:
- Feeling extremely irritable or grumpy.
- High systolic blood pressure , low diastolic blood pressure , and fast heartbeat.

- High fever.

- Symptoms of heart failure , such as breathing problems or feeling very tired.
Thyroid storm can lead to coma, heart failure , or death.
