Autoimmunity is preventable and treatable, usually without drugs. Modern medicine has potent drugs that can save lives in extreme situations such as anaphylaxis or angioedema by suppressing symptoms, but only occasionally does it deal with underlying causes. The cause of autoimmune conditions is related to overstimulation of the immune system from a toxic environment coupled with the overall wellness of the immune system.
Treatment should be focused on lowering the antigenic load (those environmental chemicals to which we're exposed), correcting a leaky gut if it is present, preserving high antioxidant reserves, balancing pH, and supporting a healthy lifestyle.
