If the production is too-small this is called hypothyroidism. TSH is distributed formally to formate the thyroid to increase production. Also, the pituitary gland stops the prodction of TSH to decrease the hormone level. However, if the thyroid gland is under attack the thyroid is not alerted. In the case of hyperthyroid, a multinodular goiter, a bumpy or enlared thyroid gland, mimicks the thyroid's functions and manufactors T3 and T4. The imposters are not aware of the pituitary gland and neither does the pituitary gland to the nodules. When the incrased production of hormones start to devlope, the pituitary gland stops TSH. Though the nodules do not recogize the stop of TSH, the production keeps on going. In another similar case, a disease called Graves" is a self attacking disease that the body turns against the thyroid. The antibodies that are attacking the thyroid form a miscommunication between the thyroid and the pituitary gland. The thyroid then does not ever decrease production. Thus resulting in another case of hyperthyroid. Theses nodels that devlope are sometimes usually from a unknown reason, or even radiation. Cold nodules are cells that lack information to mimick the thyroid. Instead of a danger to the thyroid, they pose a threat to the rest of your body. The reproduction can increase and devolpe to Thyroid cancer. Signs of hyperthyroid or hypothyroid can be detected by a doctor. The doctor usually can feel a firmness on or around the thyroid gland. Also, a lump may be visable on the lower neck.
Many thyroid diseases are linked through the family. A link between different disease point to a history of thyroid problems in the family. Dyslexia, prematurely gray hair, hair loss, left-handedness, and vitiligio (bleaching of the skin) are all linked to thyroid disease (1). Families that are traced with hyperthyroid, hypothyroid, or Hashimoto's disease have a dyslexic male.
