Thyroid Storm

Overview of thyroid storm

A thyroid storm is a life-threatening health condition that is associated with untreated or untreated hyperthyroidism. During this, a person’s heart rate, blood pressure, and body temperature can rise to dangerously high levels. Without prompt and hostile treatment, it is often fatal. The thyroid is a minor butterfly-shaped gland located in the middle of the lower neck. The two essential thyroid hormones shaped by the thyroid are triiodothyronine (T3) and thyroxine (T4). These control the speed at which each cell in your body works (your metabolism).

If you have hyperthyroidism, your thyroid is making too many of these two hormones. This causes all of your cells to work too fast. For example, your breathing rate and heart rate will be higher than normal. You can even speak much faster than you usually do.

Alternative names

  • Thyrotoxic storm
  • Thyrotoxic crisis
  • Hyperthyroidism storm
  • Accelerated hyperthyroidism
  • Thyroid crisis
  • Thyrotoxicosis

Symptoms of thyroid storm

Symptoms are similar to those of hyperthyroidism, but they are more sudden, severe, and extreme. This is why people with thyroid storm might not be able to seek care on their own. Common symptoms include:

  • Atrial fibrillation
  • High fever
  • Persistent sweating
  • Shaking
  • Agitation
  • Restlessness
  • Confusion
  • Diarrhoea
  • Unconsciousness

Causes of thyroid storm

It is rare. It develops in people who have hyperthyroidism but aren’t receiving appropriate treatment. This condition is marked by the extreme overproduction of the two hormones produced by the thyroid gland. Not all people with hyperthyroidism will develop thyroid storm. Causes of this condition include:

  • Severe undertreated hyperthyroidism
  • The untreated overactive thyroid gland
  • Infection associated with hyperthyroidism

Treatment for thyroid storm

Treatment for hyperthyroidism be contingent on the person’s age, the cause, the severity of the disease, and any other medical conditions they may have. This needs emergency treatment, usually in an intensive care unit. In many cases, the proper treatment regimen results in an improvement in the thyroid storm within 24 hours. The time to resolution of symptoms will likely depend on the individual factors that led the person to experience a thyroid storm and can take up to a week.

Treatment options include:

  • A beta-blocker to control heart symptoms
  • Potassium iodide
  • A glucocorticoid
  • Propylthiouracil or methimazole

Diagnosis of thyroid storm

People with hyperthyroidism who experience any symptoms are usually admitted to an emergency room. People with this, usually have an increased heart rate as well as a high peak blood pressure (systolic blood pressure) number.

A doctor will amount your thyroid hormone levels with a blood test. Thyroid-stimulating hormone (TSH) heights incline to be low in hyperthyroidism. Rendering to the American Connotation for Clinical Chemistry (AACC), normal TSH values range from 0.4 to 4 milli-international units per litre (mIU / L). The hormones T3 and T4 are higher than normal in people with a thyroid storm.

Possible complications

Irregular heart rhythms (arrhythmias) can occur. Heart failure and pulmonary edema can develop rapidly and cause death.


To prevent thyroid storm, hyperthyroidism must be treated.
