Thyroid .. King Maker Of Diseases
Thyroid disorders are very common among women now days, as they undergo many hormonal changes during puberty, pregnancy and menopause. Physicians probe further investigations on thyroid profile now because thyroid disorder is considered as a "the King Maker of the other diseases."
Our physical and mental make up would change if the secretions are low or high. Sometimes the thyroid enlarges uniformly or diffusely with or without nodules. Normally the thyroid swells up in deficiency of dietary iodine as everybody knows it as goiter, but there is some category of lumps, which threatens the possibility of cancer.
The function of the thyroid gland is to take iodine found from food and convert into thyroid hormones. Every cell in the body depends upon thyroid hormones for regulation of their metabolism, which affect heartbeat, cholesterol level, body weight, energy level, muscle strength, skin condition, vision, menstrual regularity, mental state and a host of other conditions of the individual.
The most common thyroid disorder is under active thyroid called as Hypothyroidism. This results when the thyroid fails to produce adequate hormones. Less frequently, an overactive thyroid condition called hyperthyroidism occurs when the thyroid produces more thyroid hormone than needed. Hyperthyroidism patients suffer enlargement. Thyroid swells up mostly with Hyperthyroidism.
The thyroid is a butterfly shaped gland, which wraps around the front part of the windpipe just below the Adam's Apple. It produces two hormones T3 and T4 to regulate every organ, every tissue and every cell in the body. The body's master gland, called the pituitary, monitors the levels of thyroid hormones in blood and regulates the thyroid gland by making a Thyroid-Stimulating Hormone.
The abbreviated term TSH is highly important investigation of a thyroid disorder. When there is less secretion the hormone level boosts up and in higher levels declines. The feedback for secretion is received from hypothalamus. This center collects signals from the cells and sends to our pituitary.
How does the thyroid gland function?
The function of the thyroid gland is to take iodine, found in many foods, and convert it into thyroid hormones: thyroxine (T4) and triiodothyronine (T3). Thyroid cells are the only cells in the body which can absorb iodine. Iodine is an integral component in the creation of thyroid hormone and, thus it’s elemental to our lives.
The major thyroid hormone secreted by the thyroid gland is thyroxine; it is also called T4 because it contains four iodine atoms. To exert its effects, T4 is converted to triiodothyronine (T3) by the removal of an iodine atom. This occurs mainly in the liver and in certain tissues.
The amount of T4 produced by the thyroid gland is controlled by another hormone TSH (Thyroid Stimulating Hormone), which is made in the pituitary gland located at the base of the brain. The amount of TSH that the pituitary sends into the blood stream depends on the amount of T4. If the pituitary sees very little T4, then it produces more TSH to tell the thyroid gland to produce more T4 hormone.
When the T4 in the bloodstream goes above a certain level, the pituitary’s production of TSH is shut off. It is just like functioning of Air conditioner and its thermostat. When the Air Conditioner fills the room cold, the thermostat reads the temperature and turns off. The thermostat starts the Air Conditioner when the room temperature becomes hot.
