I'm not here to argue either. As I noted previously, asthma is partly genetic--meaning we can be born with a genetic predisposition to it, but that doesn't mean everyone with a predisposition to it will eventually "get" asthma. It requires triggers from allergies, the environment, and viral infections. So it doesn't mean that our genes have changed--it means that other factors have been brought into the equation over time during our lives. It sounds as if your pulmonologist has noticed an improvement in the functioning of your immune system--and that alone would have resulted in an improvement in your asthma and general health. I'm still not sure I buy that chiropractic can have an effect on the immune system though (just my opinion). Joan In a message dated 1/27/2009 6:41:19 P.M.
