About Thyroid Health


Possible Causes of Hyperthyroidism

  • Graves' disease:
    The release of excess hormones is triggered by an autoimmune disorder. For some unknown reason, the body attacks the thyroid, causing it to spill out too much hormone.
  • Toxic adenomas:
    Nodules (abnormal growths or lumps) develop in the thyroid gland and begin to secrete thyroid hormones, upsetting the body's chemical balance; some goiters may contain several of these nodules.
  • Subacute thyroiditis:
    Painful inflammation of the thyroid causes the gland to enlarge and "leak" excess hormones, resulting in temporary hyperthyroidism, which resolves spontaneously. Subacute thyroiditis generally lasts a few weeks but may persist for months.
  • Pituitary gland malfunctions, or cancerous growths in the thyroid gland:
    Although rare, hyperthyroidism can also develop from these causes.
  • Silent thyroiditis:
    Usually a temporary state of excess thyroid hormone release causing mild hyperthyroidism. In some cases, it can result in permanent damage to the thyroid and low thyroid hormone production by the gland.
  • Postpartum thyroiditis:
    A type of hyperthyroidism that occurs in a small percentage of women within months of delivery. It lasts only a few months, followed by several months of reduced amounts of thyroid hormone production by the gland. Typically, these women fully recover normal thyroid function.
  • Ingestion of excess thyroid hormone:
    Can result in hyperthyroidism.
