Illnesses by environmental factors from”inside” or “outside” are chronic multisystem illnesses and mostly chronically inflammatory illnesses. Their causes can date back for decades. Almost always they are without direct organ relation and always “multifaktoriell”, i. e. several factors are always responsible for the origin of such an illness.
Besides the topical illness cause (Trigger) itself is not mostly the real problem, but it provides as the “drop too much” for the loss of the tolerance of the immune system.
Also an easy dental filling or a root treatment can be such a drop.
