Toxic Goiter Underlying Cause
The thyroid gland produces thyroid hormone, which regulates the activity of all cells in the body. The cells in the thyroid gland are stimulated by a hormone, called thyroid stimulating hormone, which is made by the pituitary gland in the brain. The thyroid cells use iodine to make thyroid hormone. A goiter occurs when the cells of the thyroid are stimulated to grow.
The thyroid cells are stimulated to grow, which may result in:
- Excess thyroid hormone levels
- Low thyroid hormone levels
- Normal levels of thyroid hormone
A goiter that produces excess thyroid hormone is called a toxic goiter. A non-toxic goiter produces normal levels of thyroid hormone.
Causes of goiter include:
