What are the functions of the t3 and t4 hormone?

Thyroid hormones T4 (thyroxine) and T3 (triiodothyronine) control the metabolism of all the cells in the body. T4 is known as storage hormone and is the main thyroid hormone produced by the thyroid gland. The 4 indicates the number of iodine molecules attached to it. T4 cannot be used directly by the body until an iodine molecule is dropped and it becomes T3. This is called conversion. T3 is the hormone actually used by cells.

What stimulates production of t3 and t4?

Thyroid stimulating hormone (TSH) stimulates the thyroid gland to produce T4 (Thyroxine).

What is the hormone produced in inadequate amounts that directly results in a goiter?

It is a hormone called T4, or thyroxin. What would normally happen is that Thyroid Stimulating Hormone (TSH) from the anterior pituitary would stimulate the thyroid to release T4. When enough T4 is produced, it inhibits TSH, or thyroid stimulating hormone, from being secreted. However if enough T4 is not released to inhibit TSH (probably due to an iodine deficiency), then TSH keeps on secreting, overstimulating the thyroid and causing the swelling known as goiter.

What does it mean when your t4 free levels are dropping?

T4 is the main thyroid hormone. If your levels are dropping, then your thyroid gland is not producing enough hormone or something is interfering with the hormone's action somehow. In either case, your doctor will need to determine if you need to supplement your T4 with oral medication.

There are twelve bones in the thoracic region.If the term is written as T4, where the 4 is a subscript, it is the symbol for thyroxine which is a hormone secreted by the thyroid gland and is essential to metabolic functions.T4 is also used for Thyroid Hormone (Thyroxine). In Endocrinology it is used in common.

Can you drink alcohol whilst taking thyroxine?

You can, but alcohol is likely to impair the T4 to T3 conversion process which is essential in gaining any benefit from this medicine. Research on alcoholics showed that T4 was more likely to convert to rT3 (the inactive form of the hormone) than T3, but when they stopped drinking alcohol, over 60% more of the T4 converted properly.
