Jennifer Hawke-Petit and her two daughters were raped and murdered, while her husband, Dr. William Petit, was injured during a home invasion in Cheshire, Connecticut.
This signal is called thyroid stimulating hormone (TSH). As the name implies, this hormone stimulates the thyroid to produce thyroid hormone and to grow in size. This abnormal growth in size produces what is termed a âgoiter.â Thus, iodine deficiency is one cause of goiter development. Wherever iodine deficiency is common, goiter will be common.
Therefore, higher TSH levels than normal suggests a thyroid that is under-active and not doing its job of producing thyroid hormone. So, in general, higher levels of thyroid stimulating hormone equals an under-active thyroid; or hypothyroidism. And the opposite is true.
