Bronx,

The quick answer is maybe. Not all airlines have a medical exam and simply ask for a current 1st or 2nd class medical. I've never been asked about my medical history during an interview, and I've never asked during any interview I've conducted.

With all that said, the bigger question is why would you want to put passengers in potential danger by flying with a known condition? I realize you must have a love for flying, but your passengers also have a love for many things and shouldn't be unknowingly in danger.

You can go to Virtual Flight Surgeons and try and get some FAA information.
