Pituitary tumor
Sheehan's syndrome (postpartum)
Autoimmune hypohysitis
TSH levels in:

Thyrotoxicosis
Tissue is exposed to excess thyroid hormone
Can be caused by hyperthyroidism
Grave's disease
Hyperthyroidism from diffuse toxic goiter
Caused by TSH receptor-stimulating autoantibodies
Continuous thyroid hormone synthesis
Treatment of thyrotoxicosis
Antithyroid agents - block hormone synthesis
Radioactive iodine therapy (resulting hypothyroidism)
Subtotal thyroidectomy (resulting hypoparathyroidism)
Causes of hyperthyroidism
Grave's disease
