*Thyroid-Associated Ophthalmopathy:


Graves disease often responds well to treatment. However, thyroid surgery or radioactive iodine usually will cause hypothyroidism. Without getting the correct dose of thyroid hormone replacement, hypothyroidism can lead to:
* Depression
* Mental and physical sluggishness
* Weight gain


Antithyroid medications can also have serious side effects.


If left untreated, more serious complications could result, including [[birth defect]]s in pregnancy, increased risk of a [[miscarriage]], and in extreme cases, death. Graves-Basedow disease is often accompanied by an increase in heart rate, which may lead to further heart complications. If the eyes are proptotic (bulging) severely enough that the lids do not close completely at night, severe dryness will occur with a very high risk of a secondary corneal infection which could lead to blindness. Pressure on the optic nerve behind the globe can lead to visual field defects and vision loss as well.

Overview

Natural History, Complications and Prognosis

Natural History

If left untreated it may lead to serious complications such as, thyroid storm, life threatening arrhythmias, orbitopathies, weight loss and even osteoporosis.

Complications

Cardiac complications

  • Older patients are more vulnerable to develop cardiovascular complications comparing to young people.[1]
  • When compared with people older than 60 years with a healthy thyroid, those who are hyperthyroid have three times the risk of atrial fibrillation.[2]
  • Thyroid-Associated Ophthalmopathy:



  • Complications from surgery, including:
    • Hoarseness from damage to the nerve leading to the voice box
    • Low calcium levels from damage to the parathyroid glands (located near the thyroid gland)
    • Scarring of the neck
  • Eye problems (called Graves ophthalmopathy or exophthalmos
  • Heart-related complications, including:
  • Thyroid crisis (thyrotoxic storm), a severe worsening of overactive thyroid gland symptoms
  • Increased risk for osteoporosis, if hyperthyroidism is present for a long time
  • Complications related to thyroid hormone replacement
    • If too little hormone is given, fatigue, weight gain, high cholesterol, depression, physical sluggishness, and other symptoms of hypothyroidism can occur
    • If too much hormone is given, symptoms of hyperthyroidism will return
