A goiter occurs when the thyroid glands are producing overly some(prenominal) endocrine gland or too little hormone or even the correct amount of hormone.
One of the star(p) causes of goiter are imputable to ace deficiency.
Over 80 years ago goiters were very frequent in the join States but is not longer seen due to the national iodine substitution program.
The primary purpose of the thyroid gland is to focus on iodine from the blood and make thyroid hormones.
Without a satisfactory amount of iodine in the blood the thyroid gland can not make enough thyroid hormone.
cod to an insufficient amount of iodine the pituitary gland in the brain senses the low amount of thyroid hormones and sends a luff to the thyroid.
This signal is called thyroid stimulating hormone also cognise as TSH
This hormone stimulates the thyroid to produce thyroid hormones and to jump in size.
Iodine suffentiency is the leading cause of goiter development.
in that respect are several other causes of goiter such as hashimotos thyroiditis is a more common cause of goiter in the united states.
This is an auto resistant condition in which the immune system destructs the thyroid glands.
Damages caused by the immune system make the thyroids less able to make forswear supplies of hormone.
Pituitary glands sense the low hormone levels and secrete more THS, causing the thyroid to grow and may produce a goiter.
Another cause of the goiter is graves disease this is due to the production of a protein called the thyroid stimulating immunoglobulin nurture referred to as TSI.
The TSI is very similar to the TSH which stimulates the thyroid gland to enlarge, producing a goiter.
TSI also stimulates the thyroid to make too much thyroid hormones.
The pituitary sences to much hormone and stops producing THS.
In spite of the thyroid gland it continues to grow and make thyroid...If you wish to get a full essay, order it on our website: Ordercustompaper.com
