Why Thyroid Gland Important

In the United States, thyroid conditions affect “nearly 30 million Americans, and yet more than half of them remain undiagnosed, “ Dr. Simona Scumpia (2006) warns. The disease is more common than diabetes or heart disease. Thyroid conditions can lead a person to develop other health problems, such as heart disease, high cholesterol, osteoporosis, and depression. Dr. Simona Scumpia, Medical Director of the Austin Thyroid and Endocrinology Center, explains: "Because the symptoms of thyroidism can be associated with commonly occurring conditions, it is extremely important that people who have the symptoms be checked with a test known as a TSH test.” The TSH test, or Thyroid-Stimulating Hormone test, is a simple blood test that measures the thyroid gland's condition.

Week 3 – LOM Assignment The thyroid is responsible for taking iodine and converting it into thyroid hormones which are released into the blood stream and transported throughout the body where they control metabolism.1 The thyroid is a vital part of the human body as every cell in the body depends on it for metabolic regulation. Too much or too little thyroid hormone secretion can result in hyperthyroidism or hypothyroidism. Hyperthyroidism is caused when the thyroid secretes too many thyroid hormones. Hyperthyroidism causes a rapid heart rate, elevated blood pressure and tremors. Other symptoms include increased nervousness, inability to concentrate, weakness, restlessness, difficulty sleeping, frequent bowel movements, weight loss and irregular

The thyroid is a butterfly-shaped gland. You would find it located in the lower neck, right below the Adam’s apple. The location is the same in both men and women. What the thyroid does is create and store thyroid hormone. It then releases the hormone in appropriate amounts to keep the body’s metabolism functioning at a normal level. If there is too much thyroid hormone, this is known as hyperthyroidism. In hyperthyroidism, the body’s metabolism increases. This condition can cause high blood pressure, high heart rate, nervousness, palpitations, and severe weight loss. Too little thyroid hormone, on the other hand, can cause tiredness, depression, memory loss, dry skin, brittle hair, and weight gain—among many other symptoms.

Commonly, problems with the thyroid involve an abnormal production level of these hormones. It is called hyperthyroidism if there the thyroid hormones are overproduced, and this can cause things like Graves’ disease, Toxic adenomas, and subacute thyroiditis (7). Hypothyroidism is the underproduction of the hormones which can be caused by an inflamed thyroid, iodine deficiency, a non-functioning thyroid gland and more. Hypothyroidism is especially dangerous in infants and newborns as the lack of these thyroid hormones can lead to mental retardation and dwarfism (7). However, in humans hypothyroidism can be caused by things such as a pituitary disorder, a defective thyroid or a lack of the gland completely. (7)

The thyroid gland is the gland that makes and stores hormones that help regulate the heart rate, blood pressure, body temperature, and metabolism. Thyroid hormones are essential for the function of every cell in the body. They help regulate growth and the rate of chemical reactions in the body. Thyroid hormones also help children grow and develop. The thyroid gland is located in the lower part of the neck, below the Adam's apple, wrapped around the trachea. It has the shape of a butterfly with two lobes attached to one another by a middle part called the isthmus. The thyroid uses iodine, a mineral found in some foods and in iodized salt, to make its hormones. The two most important thyroid hormones are thyroxine (T4) and triiodothyronine

The thyroid is a part of the endocrine system. The thyroid produces two hormones that affect metabolism, heart function and brain development. The hormones also helps regulate body temperature, weight and skin dryness. The two hormones that the thyroid secrets is triiodothyronine (T3) and thyroxine (T4). Thyroid-Stimulation hormone (TSH) is secreated by the pituitary gland, also part of the endocrine system, regulates the production on thyroid hormoes. If thyroid hormones are low the pituitart gland releases more TSH and if the thyroid hormones are hign less TSH is released. If someone is has Hashimoto’s disease the function of the thyroid and pituitary gland is affected and starts to decrease the thyroid hormones in the body and causes the pituitary gland to release more TSH into the

Thyroid Function Tests: The thyroid’s job is to make thyroid hormones, which are secreted into the blood and the carried to every tissue in the body. The major thyroid hormone secreted by the thyroid gland is thyroxine, also called T4 as it contains four iodine atoms. T4 is converted to T3 (triodothyronine) by removal of iodine atom. It occurs mainly in liver and in brain. The amount of T4 produced is controlled by another hormone which is made in the pituitary gland located at the base of brain, called thyroid stimulating hormone (TSH). The amount of TSH is in the blood depends on the amount of T4 that the pituitary sees. If the pituitary sees very little T4, then it produces more TSH to tell thyroid gland to produce more T4.When T4 in the bloodstream goes above a certain level, the pituitary’s production of TSH is shut off. The thyroid and pituitary act like heater and a thermostat. If it’s cold the thermostat reads the temperature and turns on the heater. Thus, the thyroid and pituitary, like heater turn on and off. T4 and T3 circulate almost entirely proteins, and when these proteins change their level in the blood, there is change in T4 and T3 levels.

The thyroid gland is found in the front of the neck and produces two main hormones. The hormones are called thuroxine (T4) and Triiodothyronine (T3). Together these hormones regulate the body’s metabolism by increasing energy use in cells, regulate growth and development, help to maintain body temperature and aid in oxygen consumption. These two hormones are regulated by hormones produced by the hypothalamus and pituitary gland. The hypothalamus senses changes in body’s metabolic rate and releases a hormone known as thyropin-releasing hormone (TRH). This hormone then flows through connecting vessels to the pituitary gland which signals it to release another hormone. This hormone is known as thyroid-stimulating hormone (TSH). TSH then makes

Thyroid hormone production is regulated by a hormone called thyroid stimulating hormone and it is made in the brain by the pituitary gland. Since it occurs in the thyroid gland, thyroid hormones affect metabolism, brain development, body temperature, skin dryness, and it speeds up many of the body’s functions. The

The thyroid is a small butterfly shaped gland in the front of the neck. It makes hormones called T3 and T4. They regulate how the body uses energy. Thyroid hormone levels are controlled by the pituitary, which is a pea-sized gland in the brain. It makes thyroid stimulating hormone (TSH), which triggers the thyroid to make thyroid hormone.

The central effects of hyperthyroidism are most pronounced in development. Cerebral circulation and oxygen consumption elevate. "In hyperthyroidism, Beta-adrenergic binding sites in the cerebral cortex increases and gamma-aminobutyric acid (GABA) binding sites are decreases." (Bucurescu,2014). Brain levels of serotonin, 5-hydroxyindoleacetic acid, and substance P are altered. Native pain sensitivity and number of opiate receptors are increases. Thyroid hormones affect myelination, therefore increased levels lead to oxidative damage to the myelin membrane and/or the oligodendroglial cells. The neurological manifestation is primarily due to the effect of thyroid hormones on other neurotransmitters, hormones, and generalized increased basal metabolic rate. Some of the neurological symptoms are:

The thyroid hormones, often referred to as the major metabolic hormones, affect virtually every cell in the body. Synthesis and secretion of the thyroid hormones depend on the presence of iodine and tyrosine as well as maturation of the hypothalamic-pituitary-thyroid system (Kirsten, 2000).

In the beginning, thyroid cancer doesn’t have many remarkable symptoms, but as the disease matures the following symptoms are possible:

Hyperthyroidism is a condition that affects the endocrine system, specifically the thyroid organs. The thyroid organs contain glands, which are located in front of the neck and releases hormones that control varies function in the body such as metabolism, heart rate, breathing, body temperature and several other functions in the body. This condition occurs when the thyroid glands makes an excessive amount of thyroid hormone. This results in the body system process to work on overdrive and the person can experience anxiety, rapid heart beat, excessive sweating, weight loss, and sleep problems (Aleppo 2015). Thyroid gland produces the hormones, thyroxine and triiodothyronine, which are an important part of body function. Hyperthyroidism is caused

Another condition is hypothyroidism, which is instigated by under-activity of the thyroid. Prevalence of hypothyroidism worldwide is shocking as it is estimated that 4-5% of the world population are affected by it. The symptoms of this disease are weight gain, intolerance to cold, slow heart rate and an increase in blood pressure.
