Large goiter what could be causing my levels to keep going up and the meds not to work. could you please give me some examples of what may cause this?

Goiter: Goiters (enlarged thyroid) is a common condition. Many of these are familial. If your thyroid level is either high or low, treatment can decrease the size. If your thyroid level is normal, there is very little that can be done to decrease the size other than surgery. Unless it is very large and causing compressive symptoms (trouble swallowing or breathing), usually no treatment is needed.

I don't: Know what levels you're referring to and what meds don't work. A goiter is often associated with an underactive thyroid which is easy to treat with appropriate amounts of daily brand name T4 replacement. The goiter will generally not enlarge further after that. An medical exam, other lab and an an ultrasound are indicated at least initially. Check w/your doctor.
