Of course it is just one more piece of the puzzle, not the whole answer, but it does make me think about what happens when these ulcers get going

Ok some of these autoimmune diseases(AD) your bodies defenses that fight off germs outside of the body, look at normal germs inside the body,but for some reason they don't see this as "normal". Docs try to use the biologics and immunosuupressant meds to bring your immune system off over drive. This can be difficult, however, b/c sometimes you can lower a person's immunity too much and exactly like gumby44 said it leaves you at risk for opportunistic infections like C.diff. or clostrium difficile. I know, for example, the copaxone I take for my MS mimmics the myelin coating on the nerve cells that the MS "eats" away(copaxone is a biologic med for MS, not use how any of them work for CD). I do know that I can't take biologics for CD....would "turn off" the part of the immune system that causes CD flares...would "turn on" the part of the immune system that would make my MS worse.
Does that make any sense? Have I confused you?

thanks Snohare...I just gave up my teaching job at a local college. Not seeing or knowing your audience, you don't know where they are learning wise that is....didn't want to make it too simplistic or over-the -top. Not only am I a nurse, i have CD and MS.
Thanks again
