Overview
Common risk factors in the development of multinodular goiter include female sex,age over 50 years,areas with decreased iodine intake,iodine supplementation, natural goitrogens,vitamin A and iron deficiency,selenium deficiency.
Risk Factors
- Common risk factors in the development of multinodular goiter include:
- Natural goitrogens associated with the development of multinodular goiter include:[3]
- Millet, soy beans, coconut, babassu contain flavonoids that impair thyroperoxidase.
- Cassava, sweet potato, sorghum contain cyanogenic glucosides metabolized to thiocyanates that Inhibits iodine thyroidal uptake.
- Cabbage, cauliflower, Broccoli, turnips contain glucosinolates that impair iodine thyroidal uptake.
- Seaweed (kelp) contains excess iodine that inhibits release of thyroidal hormones.
- Vitamin A and Iron deficiency increases TSH stimulation and reduces heme-dependent thyroperoxidase thyroidal activity.
- Selenium deficiency accumulates peroxidase and causes deiodinase deficiency resulting in impaired thyroid hormone synthesis.
- Iodine supplementation or iodinated contrast agents or iodinated drugs, such as amiodarone, may also induce hyperthyroidism in patients with underlying nontoxic multinodular goiter(Jod-Basedow effect).[4]
