I'm no expert yet but ever since I was diagnosed back in November I feel like I know more then half the GI's in the counrty because of my intense research which I think is beneficial for everyone who has this disease because it's so individualized.
What I did when I was first diagnosed was obvioulsy do the research but also asked a lot people who had the disease questions. I felt like my GI was obvioulsy intelligent but the real answers come from the ones who currently live with the disease.
Also, I think it's up to your GI to be asking the questions to decide what the best treatment is for you.
I hope this helps, one thing to keep in mind is that this disease is really a trial and error, you have to try things out to see if they work only becuase what works for some wont work for others.
Good Luck!
