Hi Gigi! I have MS and my 17 year old son has Crohn's. I have read that people with Crohn's are more likely to develop MS than the general population. That really scares me because I already worry about my son so much. This worries more even more since I have MS, it probably raises his risk even more due to genetic factors. It makes sense to me that you would see an immunologist. I have never mentioned any of this to my son. I don't plan on it in the near future. He is too young to worry about another health issue. I will be keeping a close eye on him though for any MS signs and so will his gastro. Please let me know how the immunologist deals with your situation. I really hope it goes well for you!
