Trouble passing gas

My son had step 1 of the j pouch surgery done April 18th.  Prior to that he had been on 6MP, Remicade, and Prednisone.  We have been in the hospital twice since his surgery. The first time for these terrible mouth sores and scrotal sores.  This time for a blood clot in his arm and huge blood pressure drops whenever he stands up.  He has had more tests and blood drawn than any person should have and they really don't have any answers. We are SOOOO FRUSTRATED and depressed. Now our issue is twice since we have been here, he has had two occassions where he ate a larger meal or a greasier meal (a bacon cheeseburger / corn dog & fries).  After that he felt really gassy, but didn't pass any gas.  His stoma is really quiet and non active when this happens.  The backed up gas gets so bad that he throws up.  Is this just a matter of him never being able to eat these foods again or large amounts of food or is it because he's so inactive.  We tried Gas X and Beano, but neither really did anything.  I'm soooo tired of hospitals and it seems everytime we leave, we end up back with new symptoms.  NOBODY understands and I'm really at the end of my ropes. I just want him to feel better and to be able to get on with his life (which is what was supposed to happen).

lew1201-I agree with suebear, it does sound like ileus.  I know it is the hardest thing to do, but getting up and walking will do wonders.  I had several problematic days during my last surgery and the last thing I wanted to do was walk and depression comes too easy....It was the one thing that helped the problem!

Keep positive
