What Is Thyroidism?

Graves ' disease is an immune system disorder that results in the overproduction of thyroid hormones (hyperthyroidism). The thyroid gland is an important organ of the endocrine system. The gland is located at the front of the neck above where the collarbones meet. This gland releases the hormones thyroxine (T4) and triiodothyronine (T3), which control body metabolism. Controlling metabolism is important for regulating mood, weight, and mental and physical energy levels. When the body makes too much thyroid hormone, the condition is called hyperthyroidism. Graves disease is the most common cause of hyperthyroidism and is most common in women over age 20. But the disorder can occur at any age and can affect men as well. Some of the symptoms of Graves diseases are

Experts aren’t sure the exact cause of Graves’ disease because it is an autoimmune disease. There are certain risk factors associated with Graves’ disease which include genetics, gender, age, pregnancy, mental stress, and smoking. People who have family history of this disease are more likely to develop it. Also females are more likely than males to acquire Graves’ disease and onset of the disease usually occurs after the age of 20. Anatomy affected by this disease is the thyroid gland which is part of the endocrine system. It is located at the back of the neck, below the Adam’s apple. This disease doesn’t destroy the thyroid gland, instead an antibody called thyrotropin receptor antibody makes the thyroid produce large amounts of hormone. The thyroid produces two hormones, thyroxine and triiodothyronine. These hormones affect many body systems and play a key role in regulating the body’s metabolic rate. Excessive secretion of these hormones is what causes the signs and symptoms that have already been described.

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

pituitary is not creating as much TSH. This would cause the Thyroid to stop producing T4

Hashimoto thyroiditis is a common disease caused by hypothyroidism. The immune system cells attack the thyroid gland, causing inflammation and eventually destruction of the gland. This reduces the thyroids ability to make hormones. These hormones are known as thyroxine (T4) and tri-iodothyronine (T3) (Better health channel 2015).

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

TSH not only stimulates the thyroid gland to churn out more hormones. If in excess, can cause overwhelming cell growth and division to result in goiter.

Incidentally, there are actually two compounds made in the thyroid that are called thyroid hormone. The most abundant is T4, also known as thyroxine, which is then converted to T3, or triiodothyronine. T3 is the active form that produces the effects on metabolism.

Graves’ Disease is diagnosed based on a series of blood tests, in addition to displaying several symptoms. Laboratory work seeks to discover elevated levels of serum thyroxine (T4) and triiodothyronine (T3) associated with TSH [2]. T3 and T4 help control the body’s metabolism and are needed for normal growth of the developing brain. TSH or thyroid-stimulating hormone is necessary to check for thyroid gland problems and how significant the issue is. One can be diagnosed from a small risk case, in which it can be controlled by medication, to a big risk bringing thyroid cancer into consideration.

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 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

Toxic nodular goiters are nodules that secrete thyroid hormones independent of TSH stimulation. They are usually benign follicular adenomas. Nodules larger than about 3 cm can cause a thyrotoxic crisis, also known as thyroid storm. This is a life threatening emergency; death is rare if treatment is initiated early and vigorously.

Stimulate the secretion of thyroid hormones from the thyroid gland by binding to a receptor on the surface of the cells of the thyroid (G protein -coupled receptors).TSH is stimulated by TRH hormone of the hypothalamus and is inhibited by Somatostatin hormone, as well as by thyroid hormones in a negative feedback loop.

Thyroid hormones play a major role in many tissues, protein synthesis and muscle function. The thyroid gland uses iodine from the foods you eat to make two main hormones which are Triiodothyronine (T3) and Thyroxine (T4). T3 and T4 travel in your bloodstream to reach almost every cell in the body. The hormones regulate the speed with which the cells/metabolism work. For example, T3 and T4 regulate your heart rate and how fast your intestines process food. So if T3 and T4 levels are too high, your heart rate may be faster than normal, and you may have an increased rate of metabolism. This is called hyperthyroidism. A study was carried out to measure the effects of hyperthyroidism on distal muscles of the upper limb. Hand grip strength, dexterity

The thyroid gland is a butterfly shaped endocrine gland that is normally located in the lower front of the neck behind the adam 's apple and along the windpipe. The thyroid gland is very rich with blood vessels. The main purpose of the thyroid is to make, store, and release thyroid hormones into the blood which is then carried to every tissue in the body. How the works is that when you acquired iodine from the food you eat. Some food has a good source of iodine in it, for example iodine is in most foods like milk, salt, bread, etc. The Thyroid gland then takes the right amount of iodine out of your blood and uses it to make two different types of thyroid hormones. The thyroid hormones produced can be either of two different types, either thyroxine or triiodothyronine. According to the article You and Your Hormones, thyroxine is the inactive form of the thyroid hormone while Triiodothyronine is the active form of thyroid the hormone. Thyroid hormones help the body use energy, stay warm and keep the essential body organs working, for example the heart, brain, muscles and other organs. But the thyroid gland influences most of all the metabolic process in the body.
