How is factitious hyperthyroidism diagnosed?
Conclusions The diagnosis of factitious thyrotoxicosis is based upon the absence of goiter, suppressed serum Tg level, decreased radioactive iodine (RAI) uptake, and excellent response after cholestyramine treatment.
What are the four types of hyperthyroidism?
The most common forms of hyperthyroidism include diffuse toxic goiter (Graves disease), toxic multinodular goiter (Plummer disease), and toxic adenoma (see Etiology). Together with subacute thyroiditis, these conditions constitute 85-90% of all causes of elevated thyroid hormone levels.
What causes iatrogenic hyperthyroidism?
Iatrogenic thyrotoxicosis may be caused by (1) subacute thyroiditis (a result of lymphocytic infiltration, cellular injury, trauma, irradiation) with release of preformed hormones into circulation; (2) excessive ingestion of thyroid hormones (“thyrotoxicosis factitia”); (3) iodine-induced hyperthyroidism (radiologic …
What are the worst symptoms of hyperthyroidism?
Symptoms
- Unintentional weight loss, even when your appetite and food intake stay the same or increase.
- Rapid heartbeat (tachycardia) — commonly more than 100 beats a minute.
- Irregular heartbeat (arrhythmia)
- Pounding of your heart (palpitations)
- Increased appetite.
- Nervousness, anxiety and irritability.
How do you correct factitious hyperthyroidism?
Factitious hyperthyroidism will clear up on its own when you stop taking or lower the dosage of thyroid hormone.
What is borderline hyperthyroidism?
Subclinical hyperthyroidism is a condition in which you have low levels of thyroid stimulating hormone (TSH) but normal levels of T3 and T4. T4 (thyroxine) is a major hormone secreted by your thyroid gland. T3 (triiodothyronine) is a modified version of T4.
How common is factitious hyperthyroidism?
Factitious hyperthyroidism can also occur when someone takes too much thyroid hormone on purpose. This is very uncommon.
What happens if you don’t treat hyperthyroidism?
If you don’t treat hyperthyroidism, you also run the risk of developing osteoporosis. You can gradually lose bone mineral density because uncontrolled hyperthyroidism can cause your body to pull calcium and phosphate out of the bones and to excrete too much calcium and phosphorous (through the urine and stool).
