Will he ever be a healthy person?

Well he does have a chronic illness. No he will never be "normal". He will have periods in his life where he's in remission and feeling better (which doesn't mean completely 100%) and he will have periods of flares that can last weeks/months/years where he is ill. He may need to have surgeries. He will need to stay on medications to help keep the damage down, and he will most likely have to change medications when they stop working. Crohn's is a life long chronic illness that does not magically go away with any diet changes. If he feels better not eating certain foods then that's helpful, but it won't be enough alone.

Now if he's not getting the best medical attention you could see about getting a new GI doctor for him. They should be running blood work periodically, and if he's not in remission they need to stay on top of finding different medical treatments to help him. But I wish there was a way to restore our health, that would be a cure. No such thing sadly.

Chrons or yeast overgrowth is never picked up by colonoscopy or blood tests. When he eats bread and donuts and pizza with yeast he gets sick. Try a week without yeast he probably wont touch yeast again. He will know without doubt that's what it is. I am recovering well from chrons because I cut out yeast.

I agree with all of the above, except World Healing. I think he definitely needs some stool samples as well; he could have c. diff., salmonella, parasites, etc. It's pretty common for Crohnnies to get those.

Also, there is a blood test that can measure the level of Remicade in your husband's system. It's a bit pricey and not many insurances will cover it. It's called the Prometheus test. But he would do it right before a Remicade infusion, and it will tell if there's any Remicade left in his system, if he has antibodies to it, etc. I get 10 mg/kg (a double dose) every 6 weeks, and that finally got my symptoms under control.

And contrary to what your doctor says, food DOES make a difference! However, if just one bite of something is causing a full-on flare (needing steroids to make it stop) as opposed to just a day or two of symptoms that resolve on their own, then he's really not stable enough.

Also, not to do with the fevers, but it IS possible to get IBS in addition to IBD. Has he tried any medications like Immodium or other IBS meds? That might help some of the symptoms.

However, please keep in mind that while he can most likely get into remission, he will never regain 100% of his health. Just the nature of Remicade and other Crohn's meds, he'll get colds easier that will last longer, he'll have days where he just feels worn out for no reason, etc. It's hard to adjust to that reality sometimes. But you CAN have a very good quality of life, if that makes sense. What he's going through right now is not normal for having the disease under control.

Lastly (sorry, just throwing out all the thoughts in my head, lol), is he taking any supplements? It's super easy to get fatigued from Crohn's because your absorption levels go down. It would be good for him to take a multivitamin, iron, calcium (especially if he goes on steroids sometimes), vitamin D, vitamin B (especially B12 and folate)....those are the ones I take. It might help his fatigue level.

what test has he had before your move? how was he diagnosed? with us we can have an abcess that may be causing his fevers, a fistula, or any number of things. so if he has not had, say a CT scan of his abdomen or at the very least a ultra sound then it would be a prudent thing to ask for or demand .
