GD= Graves' Disease (named after Robert J. Graves) TED= Thyroid eye disease aka GED (Graves eye disease) "Permanent solutions" TT= total thyroidectomy (thyroid removed surgically) RAI= radioactive iodine or iodine I-131, used to kill off all or part of your thyroid -RAI not to be confused with thyroid uptake scan, smaller non lethal version of radioactive iodine used to find out how fast your thyroid is taking in iodine and helps doctors track how fast your thyroid is uptaking iodine. A measure of how hyper your thyroid is currently. Anti-thyroid drugs: -Tapazole (generic=methimazole) abbreviation: TAP or "meth" short for methimazole -PTU=propylthiouracil Thyroid replacement meds: Synthroid,Levothroid, Levoxyl, Synthroid, Tirosint, Unithroid, Levothyroxine (Synthetic Thyroxine/T4) Cytomel,Liothyronine (Synthetic Triiodothyronine/T3) Thyrolar, Liotrix (Synthetic Thyroxine/Triiodothyronine T4/T3 Combination) Armour thyroid, Natural dessicated thyroid or NP thyroid Definitions: Hyperthyroid- thyroid levels are above normal clinical ranges, this can include TSH, T3, T4, Reverse T3, Free T3 and Free T4 Hypothyroid- levels are below normal clinical ranges, this can include TSH, T3 and T4, Reverse T3, Free T3 and Free T4 TSH: Thyroid stimulating hormone. This is not a thyroid hormone, but rather a hormone that tells your body to turn up the heat and make more thyroid hormones or to lessen production of thyroid hormones, depending on your body's needs. -You will have TSH in your body even after thyroid is removed/killed off. If your TSH is a low number that means it's telling your body it doesn't need very much thyroid hormone (going towards hyperthyroidism), if your TSH numbers go higher that is telling your body it needs to make more thyroid(without a thyroid it is just a measure of how much your body thinks you need) T3 and T4 (Free T3, Free T4, full T3, Full T4 and other variations.): These are your actual thyroid hormones Thyroid stimulating immunoglobulin (TSI): A form of immunoglobulin G (IgG) that can bind to thyrotropin (TSH) receptors on the thyroid gland. TSIs mimic the action of TSH, causing excess secretion of thyroxine and triiodothyronine. The TSI level is abnormally high in persons with hyperthyroidism due to Graves' disease. Thyroid Peroxidase Antibodies (TPOAb): Autoantibodies to thyroid peroxidase (TPOAb) are produced within the body. The presence of TPOAb in the blood reflects a prior attack on the thyroid tissue by the body's immune system.
