Well...from what ive researched the main cause is due to little to no iodine in the diet....the standard American diet is depleted with this. In most cases, iodine supplementation such as kelp, lugols iodine solution, etc it can be fixed. When did you acquire it? I am worried bc I was born with it so Idk of that would fully help me....Idk if my body is capable of doing it without the meds. That, coupled with my docs comment(coupled with virtually no info.on it), has always stuck with me....
