I got a buddy flying Part 135. He's an ATP, typed in a King Air 350, doing charter work. Anyway, he went to the doctor, and got a possible diagnosis of hypoglycemia, and symptoms of pre-diabetes, pending blood test results. He didn't bring it up with his AME, and is trying to find info on whether this would be a disqualifier for a class 1 medical. Anyone have any ideas? I told him to not bring it up with his AME, until he has more info., or a definite diagnosis.
