I'm new to the forum and exploring a possible career change and becoming a pilot. I was diagnosed about 6 years ago with hypothyroidism and have been on medication since. Occasionally, my numbers come back elevated and my doctor adjusts the meds and then my numbers return to normal within a month or so. In reading various discussion boards, it sounds like as long as your TSH levels are normal, you can obtain a First Class Medical. That said, is it possible for an airline to know that I am hypothyroid during the interview process and for that to influence their decision to hire? With a condition like hypothyroid, I'm also wondering about the wisdom of making a career switch when this could be an ongoing issue for the rest of my life, potentially grounding me if my numbers come back elevated. I would appreciate insight from anybody who has dealt with this issue. Thanks.
