What Causes Thyroid Problems?

All types of hyperthyroidism are due to an overproduction of thyroid hormones, but the condition can occur in several ways:

  • Graves’ disease: The production of too much thyroid hormone.
  • Toxic adenomas: Nodules 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: Inflammation of the thyroid that causes the gland to “leak” excess hormones, resulting in temporary hyperthyroidism that 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.
