From Health Facts
The concept of disease, like health, depends on the expectations and beliefs of a patient. For example, some people view disease as the onset of symptoms and others view themselves as having a disease only when their life or sense of well being is disrupted.
From a naturopathic perspective health and disease are a viewed as a continuum. The transformation between health and disease assists a naturopathic doctor in determining the proper treatment strategy.
