I was diagnosed with Graves only after experiencing atrial fibrillation. At that point, the cardiologist recommended immediate RAI. Because of the severity of AF I believed there was no choice except to follow his advice. I underwent two RAI treatments and have since truly regretted it. It has been an ongoing battle to regulate the thryoid levels. More than not, I now struggle with hypo-thyroidism which presents a constant struggle with weight. (And I have recently learned that iron supplements or anything containing high levels of iron cannot be taken within 4 hours of taking synthroid — who knew?) Blood tests are conducted at least every 6 months and more often if the levels have fluctuated. I truly wish I had given the meds a chance to work first. Of course it is a personal decision but arm yourself with every bit of knowledge about your options when talking to your doctors. I have had to educate my doctors on the subject as much as I have myself.
Take care,
Jan
