Boy do I wish that I had that problem, but right now I am on predisone and I want to eat everything in sight! I haven't been on remicade so I don't have any answers. You could give your GI a call and see what he says. You could also try and drink an ensure now and then so that your body is at least getting something.... Hope that someone comes along soon with some answers for you.
Living with Crohns for 1 year. I have a wonderful husband and two beautiful little girls.
One blessing that came with my Crohns: I thank God for each day that I can get out of bed and take care of my girls and my home.
