Hey, everyone, what's up?

I got a a friend who is considering going to flight school, and he was asking me about it. (As I am currently in flight school.)

I was explaining the medical cents and he told me he had a past history of an abdominal Ernie surgery, and wondering if that would disqualify him from. A first class medical. I wasn't sure (and I'm getting some conflicting responses from google.)

Does anyone here know if a history of a hernia surgery disqualifies you from getting a first class or third class medical? Or is that something that he could just call up an AME and ask?

Thanks in advance for any helpful responses.
