• Simple diffuse goiter usually does not require any treatment as mostly it regresses on its own.
  • Endemic and multinodular goiter:
    • Iodine supplementation can be done by adding 20 mg of potassium iodide per kilogram of salt. Iodized salt has greatly reduced the incidence of goiter in region with low-iodine diet. However, it has got no effect in reducing the size of goiter. The minimum iodine dietary requirement is 50 µg daily.
    • Thyroxine supplementation may be beneficial in reducing the size of goiter.
    • Partial thyroidectomy (removal of a part of thyroid gland) may be considered for large goiter especially if it causes pressure symptoms.
    • Annual examination is necessary as it may progress to toxic multinodular goiter which is characterized by over production of thyroid hormones (hyperthyroidism).
