The functioning of thyroid glands is controlled by the pituitary glands. The pituitary glands will release TSH according to body needs, controlling the thyroid glands to secrete FT3 and FT4 hormones to organs such as the heart, lungs and kidneys. The thyroid hormones within the blood will also give feedback to the pituitary glands and control the level of hormones released. If there are problems with the immune system, the thyroid glands will continuously secrete hormones against the control of the pituitary glands, causing hyperthyroidism. This condition occurs more often among females, and among men and women between ages 25 and 30.
Hyperthyroidism may causes the following conditions, including but no limited to …
- Weight gain
- Hair loss
