Thyroxine Vs Triiodothyronine
Can any doc tell me what's the difference between thyroxine, thyrocalcitonin and triiodothyronine?
Yes: Thyroxine also known as T4 is the main product of the thyroid gland. Triiodothyronine or t3 (liothyronine) is also a product of the thyroid but most of it comes from the conversion of T4 in the human tissues by the enzyme deiodinase. T3 (liothyronine) is the active and most potent form of thyroid hormone. Thyrocalcitonin or just calcitonin is unrelated to the above two, comes from the c-cells, and affects the calcium level.
Does normal (1.01) "thyroxine (t4) free, direct, s, " normal (0.931) "tsh, " and low (67) "triiodothyronine (t3)" = Synthroid dose good? Or go up/down?
Triiodothyronine : 0.76 ng/ml; thyroxine : 5.27 ; thyroid stimulating hormone : 1.15. Is this normal?
Probably: In interpreting thyroid hormone levels, you have to consider several things: What is the clinical situation at the time of the lab draw- as stress, medications, even pregnancy can all effect the levels and what they should be. Every lab also has a slightly different 'normal' range depending on how they measure the hormone. Seeing the trend also helps - Are they stable, going up or down?See 1 more doctor answer
Tsh=2.11/t3 uptake=30.3/free t3=3.3/thyroxine=9.2/triiodothyronine=102.4/ everything is normal. Why do I still feel extremely tired and irritable?
Reverse T3 (liothyronine): RT3 was not checked. A TSH of 2 is suspicious. More info on http://drfairchild. Blogspot. Com/2012/12/proper-thyroid-testing. HtmlSee 1 more doctor answer
On syn. 50 mcg labs are: TSH 4.45; rt3 23.3; T4 10.4; t3uptake 30; free T3 3.1; triiodothyronine T3 121. Increase synthroid (thyroxine)? Don't sleep, fast heart.
100-200ngm/dl, 4.5-11: Tsh between 0.4 and 4.0 t4 4.5 to 11.2 micrigm per deciliter (mcg/dl) t3 is100to200nanogram per deciliter (ngm/dl).
Hypothyroidism: When thyroid hormone is low people symptoms are highly variable from person to person. Some people do not have symptoms from mildly low thyroid hormone. Symptoms depend on degree of deficit and amount of time the hormone has been low. Here are some symptoms that are possible; fatigue, constipation, weight gain, cold intolerance and dry skin.
Yes: Coenzyme q10 is presently being peddled for pretty much everything and if you believed what these people are saying you would at best be reading uncritically. Coenzyme q specifically helps a group of very rare diseases. Supplement makers are not held by law to the standards of truth that the healthtap team is. If you want to pay money to people for deceiving you, that's your business.See 2 more doctor answers
Depends: If you are hypothyroid, have gained weight related to hypothyroidism, and then take thyroid hormone to correct your level back to normal, you would likely lose weight. If your thyroid level is normal and you try taking thyroid hormone to lose weight, it will not work, and will likely make you gain weight, as thyroid hormone increases appetite.
