Hi, I was in the navy, untreated with PKU, and interestingly, there was also another gentlemand with PKU untreated on my ship too. He was the only person I have met in my day to day life with PKU…Anyways, he had been off diet for much longer than I had and had much more severe symptons. As time wore on it became clear to me that many problems I was facing were a direct result of not being treated. To make a long story short he and I were both honorably discharged from the Navy. Since then I have found out that you can be in the military and have PKU but it does limit the jobs you can take. Virginia Schult seemed to know quite a bit about this, as do my doctors in Virginia at the university in Richmond. Good luck and I wish you the best.
