Wellness care has existed for centuries in European and Asian cultures, but is relatively new in Western medicine. In the model of wellness care, the patient is encouraged to take a proactive role in the prevention of disease and to focus on preventative measures to optimize his or her health. To compliment this focus, the physician encourages the patient to make positive lifestyle changes, maintain the body through regular exercise and diet, and receive scheduled treatment sessions to prevent injury or illness. This proactive model can include regular screenings, vitamin/nutrient supplementation, and tissue detoxification. Regular chiropractic treatment is also an important part of wellness care to maintain spinal health and promote neurological function in the body.
