Re: what's the difference between Grave's disease and hyperthyroidism?
Hyperthyroidism is a symptom to which there can be several CAUSES.
The most common cause is Graves disease, other causes can be a hot nodule, post partum thyroiditis, etc.
With Graves, the body starts producing antibodies which overstimulate the thyroid gland, causing it to produce too much thyroid hormone (which causes the hyperthyroidism).
They don't really know what the trigger is that makes our bodies start producing TSI (the antibody that causes Graves) some think it could be an environmental trigger, others a traumatic, stressful event.
Dx Graves 4/99, tx w/Tapazole & Atenolol - Remission 7/03; Relapse 1/06, back on Tapazole, remission & off meds again 11/06.
