Combining Form Meaning Thyroid
Is there any clinical condition manifested as hypothyroidism even there's high thyriod level in plasma (assuming hormon receptor complex doesn't work)?
Yes, but rare: It has been described, but rarely. Also you can have an abnormality of thyroid binding globulin that can fool some, but not all, thyroid tests. Sometimes thyroid tests point in opposite directions for a period of time due to thyroid inflammation (thyroiditis). This is where you need to ask your doctor and maybe see an endocrinologist. ...Read moreSee 1 more doctor answer

Synthroid (thyroxine): Synthroid or some form of levothyroxine is most commonly used.

Is the risk of thyroid carcinoma increased with diagnosis of hashimoto thyroiditis when multiple thyroid adenomas are present. Tyab 2470?
Not if they function: If the adenomas are "cold" or do not function, then they are likely to be malignant. They do not show up on radionuclide scan because they do not function. Otherwise they are unlikely to be malignant. However, since you have many of them, you likely need and should get further workup, like aspiration biopsy, etc., along with treatment for your hashimoto's. ...Read more
Isn't the effect of thyroid hormones at pituitary level altered in patients without a thyroid under levothyroxine monotherapy? Therefore, TSH cannot always be considered an appropriate marker? Isn't free T4 & T3 a more approriate marker in levothyroxine-
No: If your body is not handling the levothyroxine well, your TSH level will be off and you will need to increase the dose. As long as your TSH is "normal", then it is accepting the levothyroxine as a hormone and is a good measuring parameter. Ft4 and ft3 varies throughout the day (especially if you are taking levothyroxine), thus they are not good tests to base your treatment on. ...Read moreSee 3 more doctor answers
Is there any other treatment for hypothyroidism other than Synthroid (thyroxine) or generic equivalent? Is there Add-on therapy in conjunction with synthroid (thyroxine)?
Thyroid Medications: Some people say that Armour Thyroid is better, but really it is just different. Armour is a physiological mix of T3 (liothyronine) and T4 in the form of an extract of pig thyroid gland. Levothyroxin is a synthetic T4. It is true that some patients do feel better on Armour. Some feel better on Levothyroxine. The synthetic T4s can cause more of an increase in reverse T3 (liothyronine). NO GENERICS for thyroid. ...Read moreSee 2 more doctor answers
