What Causes Goiter?

Goiter can be caused by several factors, including:

  • Iodine deficiency: Lack of iodine in the diet is a common cause of goiter, as iodine is essential for thyroid hormone production.
  • Thyroid nodules: Benign or cancerous growths on the thyroid gland can cause enlargement.
  • Thyroiditis: Inflammation of the thyroid gland due to infection, autoimmune conditions, or other causes.
  • Autoimmune diseases: Conditions such as Hashimoto’s thyroiditis or Graves’ disease can lead to goiter due to immune system dysfunction.
  • Medications: Certain medications, such as lithium or amiodarone, can cause goiter as a side effect.
