I am normally on the UC board, but look at this board from time to time. I know you cannot join the military with Crohn's or UC, but once in, it seems to be service and military specialy dependent. For example, I am active duty army (14+ years), diagnosed with UC in 2006. Right now, I am not being told I have to get out. However, this is due my military specialty (biochemist). I am able to perfrom all required duties including daily physical fitness, field exercises, etc. I have been re-evalauted the last two years and the medical officer and Commanding Officer have not pushed for a medical evaluation board (MEB). I want to stay.
If I was in a different field, I am almost positive that I would have been medically retired already.
I know that if my UC gets worse that chances are I will be sent to the MEB. I'm crossing my fingers that I can get stay healthy enough to stay and that the addition of 6MP will let me get off the prednisone. We'll see.
