When we see extremely overweight people, we tend to question the functioning of the thyroid in their bodies. Which is because it is common knowledge that the thyroid controls things such as metabolism. Hence, it is significant, to say the least, that one must have proper thyroid function.
About 25 million people in America suffer from thyroid related issues, but surprisingly, 50% of them have no clue about it. The primary concern related to the thyroid is the issue of an underperforming thyroid, also known as ‘hypothyroidism’.
How Thyroid Functions:
The pituitary gland, thyroid, and the hypothalamus are the key functionaries which are needed to produce thyroid hormones.
The release of the hormone of (TRH) thyrotropin-releasing hormonefrom the hypothalamus causes the synthesis ofpituitarythyrotropin(TSH).
Delving further, TSH regulates the making as well as secretion of T4 (inactive hormone) and T3 (active hormone) out of the requisite gland. T4 serves to signal TSH and TRH to halt the making of thyroid hormone beyond a specific amount.
In case the secretion of T4 is high, parts of it will be converted to T3. Some amounts of T3 also is converted into either Reverse T3 (RT3) or Free T3 (FT3).
