Thyroid weight gain is basically the effect of the thyroid gland not working properly. It is through this gland that the thyroid hormone is being produced.
Normal levels of the thyroid hormone make it possible for the various functions of the body to maintain its normal activity. A decrease in the production of the thyroid hormone and the body’s level of activity also decreases.
When the thyroid gland produces less of the thyroid hormone, many other things happen to the body. With the cells using lesser energy due to decreased activity, less heat is produced. With less heat, the sweat glands no longer need to keep the skin moist as the body also becomes colder.
The opposite is true when the thyroid gland begins to produce the right amount of hormones that the body needs.
But an overactive thyroid gland also is not good. Aside from the above effects, an overactive thyroid also enables the body to produce more heat as a by-product of the increased activity.
In the body, it is the pituitary gland that sets the level of activity in the thyroid gland. Located at the base of the brain right between the temples, the pituitary gland sets the level in which the thyroid gland functions and, in so doing, regulates how much of the thyroid hormone is released into the blood stream.
If there the pituitary gland detects decreased levels of the thyroid hormone in the bloodstream, it sends out more of the Thyroid Stimulating Hormone or TSH into the thyroid gland by way of the bloodstream to stimulate it to produce more thyroid hormone.
A decrease in thyroid function leads to less energy consumption in the body. This makes the body to store up excess calories in the body as fat which results in weight gain.
