fp9, I have pm'd you. It really should not be a problem. Thyroid issues are quite common and many go undiagnosed. So long as a prescribed drug regime works then you'll be fine; however, I used carbimazole as a block and replace drug. My endocrinologist recommended 3 years of this then removal of the thyroid. Problem was, after coming off carbimazole I went hyper again so total removal was only option. That's when the big C arrived during histology. I'm ok now and back flying with a full class 1 medical, restricted to as, or with copilot. I'm a Captain.
