Unfortunately, the acute-care approach to medicine is poorly designed to address chronic fatigue, autoimmunity, and other complex conditions.
Most Western medical practices do not account for the unique genetic makeup of each individual or how modern lifestyle has influenced the rise of chronic disease in our society. Most doctors simply don’t have enough time to figure out the root causes and teach their patients how to be healthy.
I believe that everyone has unlimited potential to overcome their health challenges and live their most purposeful life.
