Hyperthyroidism What is hyperthyroidism? Hyperthyroidism is a medical condition characterized by hyperactivation of the thyroid gland and release of excess thyroid hormone. The thyroid gland plays a critical role in the body’s metabolism – excess thyroid hormone results in an increased metabolic rate. This leads to features such as anxiety-agitation‚ palpitations‚ tremor‚ weight loss‚ sensitivity to heat‚ insomnia‚ increased heart rate (tachycardia)‚ and diarrhea. Serious long-term effects may

disorder in which antibodies produced by your immune system stimulate your thyroid to overproduce hormones. To attain a better idea of Graves’ disease‚ attention has to be given to how the thyroid works.The thyroid is a butterfly shaped gland under the laryngeal prominence or adam’s apple‚ that is responsible for secreting thyroid hormones thyroxine (T4) and triiodothyronine (T3) that increase the body’s metabolic rate. The thyroid is regulated by the hypothalamus gland in the brain that makes thyrotropin-releasing

(http://www.mayoclinic.org/diseases-conditions/hashimotos-disease/basics/definition/con-20030293) A large number of white blood cells also accumulate in the thyroid. These white blood cells are called lymphocytes and they are responsible for making the antibodies that start this autoimmune process. Hashimoto’s disease tends to lead to reduced thyroid function‚ known as hypothyroidism

that can go wrong. Two of the things that could go wrong are Hyperthyroidism (overactive Thyroid) and Hypothyroidism (underactive Thyroid). While they are both malfunctions of the Thyroid gland‚ Hyperthyroidism has more impact on not just teens‚ but everyone‚ than Hypothyroid does. Hyperthyroidism is when the thyroid gland releases too much T-3 and T-4. Hypothyroidism is‚ alternatively‚ when the Thyroid does not release enough T-3 or T-4. A few of the main causes of Hyperthyroidism are Graves

I have a problem. I have hypothyroidism. Hypothyroidism is when your thyroid produces too little thyroid hormones.

Circulatory Disease Thyroiditis is the inflammation of the thyroid gland. It has many causes‚ Hashimoto’s thyroiditis being the most common of them. There are also Subacute Thyroiditis and "Silent" thyroiditis‚ which occur less frequently than Hashimoto’s. Abnormal blood antibodies and white blood cells attacking and damaging thyroid cells cause this Auto Immune disorder. This is normally considered a chronic inflammatory disorder of the thyroid gland.

has no thyroid gland? Rat A (1 pts) 2. Justify your answer. (what data convinced you of your answer) (1 pts) T3 and T4 regulate the metabolism‚ so when more is available it increases the baseline metabolic rate. TSH causes the release of T3 and T4‚ so if the rat is injected with TSH‚ in theory we would suggest that the levels of T3 and T4 are also higher than the baseline metabolic rate. 3. In a further experiment‚ all 3 rats were given a drug that inhibits the production of thyroid hormone
