we need help

The first two infusions worked great and he appeared to be in remission. The last two not as well and in fact the last infusion made no difference.  He saw a nurse practioner yesterday and she wants to try some other meds.  She thinks he now has IBS and also she prescribed an anti-biotic for his stomach.  She also wants him to have another colonoscopy.  He asked her about diet and she said diet won't make a difference.  He also asked her about a natural product called Intestamine.  He even had a flyer to show her.  She wouldn't look at it.   She said the only thing that will help is medication.

My son is fed up and frustrated to the point he is going to skip all the meds and take this on himself through diet.  I feel terrible for him and don't know what I can do.  He is only 24.  I can't imagine living the rest of your life like this.

1.  Any advise for me or him.

2.  Anyone heard of intestamine.  A  friend of my wife had Crohns and she swears by it.

Thanks everyone.

My personal opinion on diet is that it is important when flaring, because certain foods can aggravate symptoms. However, you're not going to cure the disease or induce any kind of remission with a diet. Meds are mandatory for recovery in my opinion. Of course, even meds don't work for some people.

If meds aren't working it may be worth looking into surgery. I've never met one person who opted for j-pouch that wasn't happy after having it done.
