First of all the term Thyroids is normally used to indicate disturbance of the function of thyroid glands. These glands are an endocrine which locates around the trachea (lower front portion of the throat). Above all the main function of Thyroid glands are to convert iodine into hormones i.e Thyroxine (T-4) and Triiodothyronine (T-3). As a result these hormones are so important in order to regulate all kind of body’s functions or metabolism. For instance, the evolution of body tissues, energy, temperature and vitamins etc.
So the process of hormone synthesis begins in a part of the brain, called the Hypothalamus. It’s main function is to link the nervous system to the endocrine system via the pituitary gland. When Hypothalamus releases the TRH to the pituitary gland, in response; the pituitary gland then releases TSH (i.e. thyrotropin) into the blood. Consequently TSH travels to the thyroid gland and stimulates this gland to produce the two hormones T4 and T3.
CAUSES OF THYROID DISORDER
Finally a condition in which thyroid gland (TG) produces high amount of hormone is called hypothyroidism. Likewise a condition in which TG* produces low amount of hormone is called hypothyroidism.
Ratio of Thyroid disorder is quite higher in women than in men. “This hormonal imbalance can cause weight gain or make it difficult to lose weight, even with vigorous exercise and the right diet,” says Scott Isaacs, MD, medical director at Atlanta Endocrine Associates.
HYPERTHYROIDISM (EXCESSIVE THYROID HORMONE)
There are multiple factors that causes hyperthyroidism; in which Grave disease, Toxin adenomas, Subacute thyroiditis (painful inflammation of the TG), Excessive amount of iodine intakes in daily diet and pituitary gland malfunctions are significant. Even more Grave disease is an autoimmune disorder in which an antibody causes the TG to make excessive amounts of thyroid hormone. This autoimmune disorder may have a genetic component. For instance; bulging eyes, sensitivity to light, and blurry vision, redness and swelling of the skin are common symptoms of Grave disease.
COMPLICATONS OF UNTREATED HYPERTHYROIDISM
Above all that Miscarriage, preterm birth, high blood pressure during pregnancy, poor fetal growth and dysfunction of the TG, heart rhythm disorder or congestive heart disease (CHF) are all possible complications of untreated hyperthyroidism. Furthermore interferes of the body’s ability to deposit calcium into the bones that leads to osteoporosis or brittle bones is also one of them.
HYPOTHYROIDISM (LESS THYROID HORMONE)
The potential causes of hypothyroidism are Hashimoto’s thyroiditis (chronic lymphocytic thyroiditis), Thyroidectomy (i.e. removal of the TG), Drugs used in Epilepsy, chemotherapy, used to fight infection etc. Even more in hashimoto’s thyroiditis TG is being destroyed by the immune system and affects women seven times more than it does in men.
COMPLICATONS OF UNTREATED HYPOTHYROIDISM
Consequently body loses heat faster than it can produce heat, decline of memory & thinking skills, coronary artery disease, and high concentration of fat or lipids in the blood are possible complications of untreated hypothyroidism. Furthermore decreased lung function, an abnormal enlargement of TG are also one of the causes of untreated hyperthyroidism.
*TG stands for “Thyroid Gland”
