causes,symptoms and treatments to hyperthyroidism
Common causes of hyperthyroidism in adults include: 1  Diffuse Toxic Goiter (Graves' Disease). 2  Overactivity of the entire thyroid gland caused by antibodies in the blood which stimulate the thyroid to grow and secrete excessive amounts of thyroid hormone. 3  Toxic Adenoma (hot nodule).
Symptoms are related to the effects of excess thyroid hormone. Thyroid hormones control metabolism, so excessive amounts of T4 or T3 cause a metabolic rate that is too high. This is called a hyper-metabolic state. People with hyperthyroidism typically have rapid heart rates, weight loss, and heat intolerance. The thyroid gland can be visibly enlarged (goiter). You can also have elevated blood pressure, nervousness, and hand tremors. You may also sweat a lot, feel hungry and restless, and have difficulty concentrating.
The most common cause of hypothyroidism is Hashimoto's thyroiditis. Thyroiditis is an inflammation of the thyroid gland. Hashimoto's thyroiditis is an autoimmune disorder. With Hashimotoâs, your body produces antibodies that attack and destroy the thyroid gland. Thyroiditis may also be caused by a viral infection. Other causes of hypothyroidism include: Radiation therapy to the neck area. Treating certain cancers, such as lymphoma, requires radiation to the neck. Radiation damages the cells in the thyroid. This makes it more difficult for the gland to produce hormone. Radioactive iodine treatment.
