  2. Hyperthyroidism - Wikipedia

    [1] [7] Other causes include multinodular goiter, toxic adenoma, inflammation of the thyroid, eating too much iodine, and too much synthetic thyroid hormone. [1] [2] A less common cause is a pituitary adenoma. [1] The diagnosis may be suspected based on signs and symptoms and then confirmed with blood tests. [1]

  3. Jod-Basedow phenomenon - Wikipedia

    en.wikipedia.org/wiki/Jod-Basedow_phenomenon

    The hyperthyroidism usually develops over 2 to 12 weeks following iodine administration. [ 2 ] In some ways the Jod-Basedow phenomenon is the opposite of two physiological compensation mechanisms, the Plummer effect and the Wolff–Chaikoff effect , which in normal persons and in persons with thyroid disease, suppress the thyroid hormone after ...

  4. Graves' disease - Wikipedia

    These TSI antibodies cause the thyroid gland to produce excess thyroid hormones. [1] The diagnosis may be suspected based on symptoms and confirmed with blood tests and radioiodine uptake. [1] [4] Typically, blood tests show a raised T 3 and T 4, low TSH, increased radioiodine uptake in all areas of the thyroid, and TSI antibodies. [4]

  5. Iodine in biology - Wikipedia

    en.wikipedia.org/wiki/Iodine_in_biology

    Excessive iodine intake presents symptoms similar to those of iodine deficiency. Commonly encountered symptoms are abnormal growth of the thyroid gland and disorders in functioning, [ 78 ] as well as in growth of the organism as a whole.

  6. Thyroid storm - Wikipedia

    en.wikipedia.org/wiki/Thyroid_storm

    Thyroid storm is characterized by an acute onset of symptoms of hyperthyroidism (fast heart rate, restlessness, agitation) accompanied by other features such as fever (temperatures often above 40 °C/104 °F), hypertension, mental status changes, diarrhea, and vomiting. [11] Individuals can exhibit varying signs of organ dysfunction.

  7. Thyroid disease - Wikipedia

    en.wikipedia.org/wiki/Thyroid_disease

    Radioiodine therapy with iodine-131 can be used to shrink the thyroid gland (for instance, in the case of large goiters that cause symptoms but do not harbor cancer—after evaluation and biopsy of suspicious nodules has been done), or to destroy hyperactive thyroid cells (for example, in cases of thyroid cancer). The iodine uptake can be high ...

  8. Thyroid - Wikipedia

    Another cause is excess iodine availability, either from excess ingestion, induced by the drug amiodarone, or following iodinated contrast imaging. [46] [47] Hyperthyroidism often causes a variety of non-specific symptoms including weight loss, increased appetite, insomnia, decreased tolerance of heat, tremor, palpitations, anxiety and nervousness.

  9. Goitre - Wikipedia

    en.wikipedia.org/wiki/Goitre

    Goitre is treated according to the cause. If the thyroid gland is producing an excess of thyroid hormones (T3 and T4), radioactive iodine is given to the patient to shrink the gland. If goitre is caused by iodine deficiency, small doses of iodide in the form of Lugol's iodine or KI solution are given.
