Yes, but according to other gastroenterologists/researchers etc other factors are the 'main' ones in causing crohn's. Some people have found certain things to be effective whereas others have done the same thing with no effect at all.
It is great that there are people working tirelessly to try and get a cure/prevent this disease but none of them appear to concur 100% with what is the way to go. Until this is achieved I think it is a fair comment to say that the consultants mainly go down the medicinal route to try and keep this disease somewhat under control.
I believe (but I could be wrong) but here in the UK it is not standard for people to be treated with the anti-map treatment.
I know that the stem cell treatment is still under trial but unfortunately it is not a simple case of implanting new stem cells in your stomach. The patients involved in the trial have to undergo a lengthy process (somewhere up to 2 years) which involves major chemotherapy treatment and at the end of it they may still not be cured. The thought behind this treatment is that the master cells are extracted, cleaned up and replaced in the bone marrow enabling the immune sytem to re-boot.
One day the answer will be found............
