(noun)

the excessive production of hormones by the thyroid

Examples of hyperthyroidism in the following topics:

  • Thyroid Gland Disorders

    • Thyroid disorders include hyperthyroidism (abnormally increased activity), hypothyroidism (abnormally decreased activity), and thyroid nodules, which are generally benign thyroid neoplasms, but may be thyroid cancers.
    • Hyperthyroidism, or overactive thyroid, is the overproduction of the thyroid hormones T3 and T4 .
    • In the case of Graves' disease, beta blockers are used to decrease symptoms of hyperthyroidism and anti-thyroid drugs are used to decrease the production of thyroid hormones.
    • Hypothyroid disorders may occur as a result of congenital thyroid abnormalities, autoimmune disorders such as Hashimoto's thyroiditis, iodine deficiency (more likely in poorer countries), or the removal of the thyroid following surgery to treat severe hyperthyroidism or thyroid cancer.
    • Differentiate among the types of thyroid gland disorders: hyperthyroidism, hypothyroidism, and thyroid nodules

  • Medical Imaging and Diagnostics

    • Radiation therapy uses ionizing radiation to treat conditions such as hyperthyroidism, cancer, and blood disorders.
    • Radiation therapy involves the application of ionizing radiation to treat conditions such as hyperthyroidism, thyroid cancer, and blood disorders.

  • Therapeutic Uses of Radiation

    • Radiation therapy uses ionizing radiation to treat conditions such as hyperthyroidism, cancer, and blood disorders.
    • Radiation therapy involves the application of ionizing radiation to treat conditions such as hyperthyroidism, thyroid cancer, and blood disorders.

  • Isotopes in Medicine

    • In addition to imaging, radionuclide therapy can be used to treat conditions such as hyperthyroidism, thyroid cancer, and blood disorders.

  • Development of the Endocrine System

    • Sometimes, the thyroid gland produces too much thyroxine, a condition known as hyperthyroidism.
    • Hyperthyroidism has been treated by partial removal or partial radiation destruction of the gland.

  • Type II (Cytotoxic) Reactions

    • Graves' disease is an autoimmune disease where the thyroid is overactive, producing an excessive amount of thyroid hormones (a serious metabolic imbalance known as hyperthyroidism and thyrotoxicosis).

  • Adrenal Gland Disorders

    • Autoimmune adrenalitis may be part of Type 2 autoimmune polyglandular syndrome, (which can include type 1 diabetes), hyperthyroidism, autoimmune thyroid disease (also known as autoimmune thyroiditis and Hashimoto's disease).

  • Action of Thyroid Hormones

    • One suffering from hyperthyroidism (an overactive thyroid) will experience a fever; conversely, one suffering from hypothyroidism (a less active thyroid) will suffer from a decrease in body temperature.

  • Hypertension

    • Hypertension can also be caused by endocrine conditions, such as Cushing's syndrome, hyperthyroidism, hypothyroidism and acromegaly.

  • Hormonal Regulation of Metabolism

    • Hyperthyroidism, the overproduction of thyroid hormones, can lead to an increased metabolic rate, which may cause weight loss, excess heat production, sweating, and an increased heart rate.
