A thyroid fever is actually a major symptom of thyroid storm, a life-threatening condition for some people with hyperthyroidism, or an overactive thyroid.
Hyperthyroidism causes high levels of the thyroid hormone in the bloodstream, interfering with the body’s metabolism, which the thyroid gland normally helps control.

Signs of hyperthyroidism might include sweating, palpitations and weight loss, but a high fever and other symptoms of a thyroid storm are more severe,
according to MedicineNet.com.
A fever from a thyroid storm can cause the body's temperature to rise up to 106 degrees. The fever is the result of elevated hormone levels. It is a telltale sign of thyroid storm along with other symptoms, which may include rapid or irregular heart rate, dehydration, weakness, nausea, diarrhea, confusion, heart failure, and even death.
A thyroid storm is rare, but needs immediate medical attention. It can develop from untreated or severely undertreated hyperthyroidism,
Healthline reports. An infection from an overactive thyroid gland may also result in a thyroid storm.
The risks of developing a thyroid storm increase in hyperthyroid patients who experience trauma, serious emotional distress, surgery, diabetic ketoacidosis, congestive heart failure, stroke, or pulmonary embolism.

Emergency treatment for a thyroid storm includes support measures for vital organs. To control the fever from the thyroid condition, doctors administer fever-reducing medications and may apply cooling blankets,
according to eMedicineHealth. Oxygen may also be administered if needed.
Patients may also receive intravenous fluids and medications to block the production of thyroid hormones. Treatment for heart failure may be necessary.
Doctors carefully monitor a patient’s condition during treatment, which often takes place in an intensive care unit. When it appears a thyroid storm and fever have diminished, doctors may use radioactive iodine or medications to keep the overactive thyroid under control.
Follow-up visits to a doctor are important to continue treatment for hyperthyroidism. Early and proper treatment of an overactive thyroid helps to avoid the frightening symptoms of fever and other reactions from a thyroid storm.
