Graves Disease


Graves disease is an autoimmune disease that causes your immune system to attack your thyroid gland. This causes your body to make too much thyroid hormone and leads to hyperthyroidism. The thyroid gland is a butterfly-shaped organ that is found in the front part of your neck. Thyroid hormones regulate body temperature, heart rate, and weight.

is an EKG that stays on continuously to record your heart's electrical activity.


  • Antithyroid medicines decrease thyroid hormone levels and your symptoms.
  • Heart medicine may be given to control and regulate your heart rate.


  • Blood tests will be done to measure your thyroid levels. They may also be done to check for antibodies that show you may have Graves disease.
  • Radioactive iodine uptake tests may be done to show how well your thyroid works. It may show that your thyroid gland is producing too much hormone.
  • A thyroid scan may be done to show the size, shape, and position of your thyroid. A small amount of radioactive tracer is given to create pictures of your thyroid.


  • IV fluids may be given through a tube that is placed in your vein.
  • Radioactive iodine is given to damage or kill some thyroid gland cells. This may decrease the amount of thyroid hormone produced. Tell your healthcare provider if you are breastfeeding, or you know or think you are pregnant. This medicine can be harmful to your baby.
  • Surgery may be done to remove all or part of the thyroid gland.


Thyroid storm is a sudden, severe increase in your thyroid hormone levels. A thyroid storm can happen if you have untreated hyperthyroidism. A thyroid storm can be triggered by an infection, a serious injury, or surgery. A thyroid storm can cause a fever, fast heartbeat, increased sweating, vomiting, diarrhea, and trouble thinking. You may have seizures or go into a coma. A thyroid storm can be life-threatening.
