Is there asubclincal hyperthyroidism?

my TSHis low .01 iam not suffering from the usual hyperthyroidism my resting pulse is 81 b/m do ihaveit?

Not all instances of a low TSH are caused by subclinical hyperthryoidism. TSH receptor antibodies falsely lower TSH, and many medications including corticosteroids and dexamethasone lower TSH. Many other conditions such as endogenous depression and post-surgical recovery also cause a low TSH. A low TSH can be a protective mechanism when patients are bedridden and have a reduced need for thyroid hormone. TSH orders thyroid cells to grow and produce more thyroid hormone. A low TSH in itself only has the effect of reducing thryoid hormone production.

Many patients with a diagnosis of subclinical HyperT have successfully raised their TSH levels by means of alternative medicine. Dietary changes, including the addition of goitrogens, avoiding excess dietary iodine in fast foods and incorporating stress reduction techniques are particularly beneficial.

Avoiding known allergens and other environmental triggers, such as aspartame, can also correct subclinical hyperthryoidism. Adding 100-200 mcg selenium can also help. Recent studies show that selenium deficiency contributes to the development of iodine since selenium is necessary for normal thryoid function. The amino acid acetyl-carnithine also is known to reduce symptoms of hyperthryoidism.

As a brief review of thyroid function, the hypothalamus in the brain regulates thyroid hormone levels. When the hypothalamus (as well as several neurotransmitters) detects low thyroid hormone levels, it orders the pituitary gland to release a hormone known as thyroid stimulating hormone (TSH or thyrotropin). When thyroid hormone levels are high, the hypothalamus suppresses the normal pulsating release of TSH. Normally, TSH is released on a constant schedule with peak levels secreted during the night.
