Answer 3/3 - Submitted 10/12/2010
Although I have no major medical background, some quick research shows the possible causes of goiter associated with hypothyroidism.
- Inborn errors of thyroid hormone synthesis, causing congenital hypothyroidism (condition from birth)
- Ingestion of goitrogens, such as cassava.
- Side-effects of pharmacological therapy.
Of course, the leading cause of goiter worldwide is an iodine deficiency, however if you are in North America I do not think this is likely. My (unprofessional) opinion is that it is related to your hypothyroidism. It is likely that your doctor will put you on a prescription. There is a chance that your condition may require an operation, but if it does it is a simple one.
Hope this helps!
