I have rheumatoid arthritis - a diagnosed autoimmune disease, and most of my readers have autoimmune diagnoses as well. But what if you have symptoms with no known cause? You've gone from doctor to doctor, and they simply tell you: "Your lab tests are normal." While in some ways this is good news, it can also be incredibly disheartening. You have no answers and no direction about what to do next. Dr. Tom O'Bryan is an expert on the development of autoimmune disease, and he writes about the autoimmune spectrum. The autoimmune process begins in our bodies long before enough damage has occurred to warrant a diagnosis. His goal is to help people intervene at this point (or even before they have symptoms) and prevent autoimmune disease before it takes hold. That's what today's podcast is all about.
