Low T4 Thyroid Hormone What Does This Mean
How/Does Thyroid hormone production normally fluctuate along with female hormone cycle? Are you more likely to have hi/lower t4/t3 at certain times?
No "DIRECT" connection between thyroid gland output and t-4/t3 ratios and "female hormones" except that the BINDING of the hormone itself is altered by female hormone levels...This does not generally effect the end point of Thyroid Hormone effects (on growth, muscles and other tissues)
Hope this helps!
Perhaps a more specific question can generate a better answer!

A hormone (from greek ὁρμή, "impetus") is a chemical released by a cell or a gland in one part of the body that sends out messages that affect cells in other parts of the organism. Only a little amount of hormone is required to alter cell metabolism. In essence, it is a chemical messenger that transports a signal from ...Read more
My T3 (liothyronine) is 101.80 ng/dl, T4 is 6.60 ug/dl, TSH is 1.460 uiu/ml. Is hypothyroidism still possible with normal thyroid hormone test results?
Thyroxine is a type: The thyroid gland secretes two types of hormones: thyroxine (t4) and triiodothyronine (t3), but it produces T4 at much higher levels than t3. When treating thyroid hormone deficiency, your physician may prescribe levothyroxine (which is oral tablet of t4), liothyronine (oral formulation of t3), or combinations of such, or even dessicated (dried) pig thyroid as replacement therapy. ...Read moreSee 2 more doctor answers
So the internist said it wasn't necessary for my mom to increase her synthroid (thyroxine) dosage of 25 mcg because she has active thyroid hormone (T3) of 2.9. Do you agree?
Either way: There is a very common condition called "post partum thyroiditis". It can cause fluctuations in your thyroid function leading to both high and low hormone levels. Sometimes it requires medication, but sometimes it levels out on its own. You may need to consult with an endocrinologist. ...Read more
Allopecia: If scalp hair loss called allopecia is due to hypothyroidism one can reverse it by normalizing thyroid function. Most of the time hypothyroidism is due to an autoimmune disorder called hashimotos disease. Allopcia is an accompanying autoimmune disorder and may not be due to low thyroid hormones. It's an association -- not causation. ...Read moreSee 2 more doctor answers
Are thyroid nodules always thyroid cancer? I have a thyroid nodule and my levels of some thyroid hormone are low. My doctor wants to do more tests, but I don’t really understand what he said. Do I have cancer, or could it be something else?
Over: Over 95% of thyroid nodules are benign. Therefore the risk of cancer is low, but can be increased in younger or older people, people with a family history of thyroid cancer, or people who have been exposed to radiation (x-rays do not count). Sometimes benign thyroid nodules can secrete extra thyroid hormone, more than your body needs. If your doctor is suspicious of this, they will order a nuclear study called a thyroid uptake and scan. If a nodule is over a centimeter, that is when we usually will perform a fine needle aspiration to get a sample of cells in the nodule. If nodules are under a centimeter and there is no evidence of over activity, we can simply monitor with serial ultrasounds. ...Read moreSee 1 more doctor answer
Do I need thyroid hormone if I have low free t3, (liothyronine) normal TSH and high tpo antibodies?
Possibly.: The TSH is normal so it might be a variation of normal or euthyroid. It also might be a developing thyroid condition, but there would be symptoms, like fatigue. The tpo antibodies might mean hashimoto's thyroiditis. This is usually associated with hypothyroidism. It would be wise to see your doctor to follow up. ...Read moreSee 1 more doctor answer
