Medicine divides diseases, symptoms, and syndromes into so many differently named diseases, that no one person can know it all. Specialization makes the quantity of medical knowledge more manageable, and at the same time impedes discovery of the root causes of chronic disease. The root causes of chronic disease may have occurred years or decades prior to the diagnosis, may have been seen or treated by a different specialty, or knowledge of the root cause is not within the specialists’ scope of knowledge.
