Traditional medicine looks only at the absence of disease as the definition of being healthy. Most of the time, doctors simply treat the symptoms of a disease or try to detect them early on so that they can be treated with traditional medications. Anti-aging medicine is more concerned about the whole person and achieving optimal health. It looks at and considers factors which are physical, but also factors in emotional and mental health aspects. Anti-aging medicine considers hormones, toxins, organ systems, as well as nutrition and stress factors in developing optimal health that will also be effective at preventing disease.
