by: Joe Hing Kwok Chu 按 此看中药治療法
It is the condition of insufficient thyroid hormone.
Causes
The problems can be originated from the thyroid glands or from the pituitary gland or even from the hypothalamus.
1. chronic inflammation
The most common cause of this is autoimmune dysfunction where the auto-immune system attacks the thyroid gland. It is called autoimmune thyroiditis or Hashimoto's disease (橋本病), (also called chronic lymphocyctic thyroiditis).
2. results of medical procedure: surgically removing part or all of the thyroid glands or using radioactive iodine to kill the thyroid cells in preventing the glands from growing larger, usually in hyperthyroid therapy or in cancer therapy.
3. weak signal from the pituitary caused by low thyroid stimulating hormone (TSH).

Thyroid-Stimulating Hormone (TSH)

Elevated values indicate primary hypothyroidism.
Low values indicate hyperthyroidism.
A small percentage of the population, especially the elderly patients, may have low TSH values.
Interfering Factors and Clinical Implications Elevated Levels:
Primary hypothyroidism
TSH producing pituitary tumors (rare)
Pituitary and peripheral tissue resistance to thyroid hormone (rare)
Low levels:
Hyperthyroidism
thyroid hormone therapy
Euthyroid sick state (low plasma T3 despite a normally functioning thyroid despite normal thyroid function)
Severe psychiatric disease (especially manic depression)
Corticosteroid therapy
Dopamine infusion
Drug Therapy
