Thyroid Disorder Outline

Hashimoto’s Thyroiditis, also called Hashimoto’s disease is an autoimmune disease in which the body’s immune system attacks the thyroid gland. It was named for the Japanese surgeon who discovered it in 1912 The thyroid is a small butterfly shaped gland in the front of the neck. The thyroid makes hormones called T3 and T4. These hormones regulate metabolism. The thyroid is controlled by hormones of the pituitary gland, which is also called the “master gland.” It is a pea-sized gland located in the base of the brain which, among others, makes thyroid stimulating hormone, or TSH. TSH stimulates the thyroid to make thyroid hormone. With Hashimoto’s disease, the thyroid cells are damaged resulting in the inability to make enough thyroid

2. The subject who was diagnosed with secondary hypothyroidism was given levothyroxine (synthetic Thyroxine). After 6 weeks of

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

3. As hypothyroidism progresses, symptoms will start to occur including fatigue, weight gain, cold intolerance, peripheral neuropathy, memory loss, sleep apnea, and daytime drowsiness.

Hypothyroidism and hyperthyroidism are easily confused because the words are so similar-looking. But knowing a bit of ancient Greek and using common sense can help your remember the difference.

Thyroid research came about after a paper published in 1850, written by Thomas Curling talking about two girls who had severe malformation and were placed in an idiot asylum. One of the girls, 10, could not walk or talk very well; the other, 6 months, “was plump but had a marked idiotic expression, a large face with a small

You may not have known this before you got news of your condition, but Hashimoto’s disease is the most common cause of hypothyroidism in the developed world, and it affects literally millions of patients. You are definitely not alone with this condition! “Hypothyroidism” is a medical term, and what it means is simply low thyroid

Diagnosis of a thyroid disorder is based on the levels of thyroid-stimulating hormone, thyroxine T4) and triiodothyronine (T3) in the blood (McCance & Huether, 2014). When these levels are not within range, either hypothyroidism or hyperthyroidism can occur. With Graves disease the dysfunction is directly linked to a hypersensitivity type II, which targets auto antibodies to a specific tissue (McCance & Huether, 2014). These antibodies are known as thyroid-stimulating immunoglobins (McCance & Huether, 2014).

Hypothyroidism is caused by the thyroid’s gland inability to produce thyroid hormone as required by the body. The diagnosis of hypothyroidism requires the laboratory testing of the thyroid stimulating hormone known as TSH. When the TSH is found to be elevated, a clinician should repeat the test along with a free thyroxine (T4) measurement. If the TSH is found to be elevated, while the T4 is normal, the patient is said to suffer from subclinical hypothyroidism. However, if the TSH is elevated and the T4 is low, the diagnosis is primary hypothyroidism (Gaitonde et al., 2012).

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)

Credibility Statement: Your thyroid controls so much in your body and not many people are aware of what can happen if you get one of two thyroid disorders. Your thyroid controls most things from your sleep pattern to your weight to your heartbeat and more. Both disorders are nothing to overlook by no

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

Both hypo and hyperthyroidism are a result of a disease in caused by malfunction of the thyroid gland located in the neck as represented by the image below left. The causes of chronic hypothyroidism are fairly distinct. Around the world in third-world and developing countries, iodine deficiency is the most common cause of hypothyroidism. This used to be true as well for developed countries, but today this is a less common cause as iodine usually finds its way into our diets without too much trouble. In modern-day developed countries, hypothyroidism is mainly a result of Hashimoto's thyroiditis, a birth defect which lacks a thyroid gland or a deficiency of hormones from either the hypothalamus or the pituitary gland.
