In today's world, a large proportion of our population is constantly in the state of pre-illness due to polluted environments, contaminated food-chains, mental stresses and unhealthy lifestyles. Every year, tremendous amount of money has been spent on research and development of drugs and therapies to treat diseases. However, this has limited effects on improving the health and wellness of our population. Our healthcare systems are facing great challenge we have never seen before. People finally have realized that it is wise to prevent any deterioration in their health rather than seek a cure after illness prevails.
Although many diseases can be prevented, current healthcare systems can hardly support this practice. Most healthcare systems are based on responding to acute problems and urgent needs of patients. Testing, diagnosing, relieving symptoms, and expecting a cure are hallmarks of contemporary healthcare. While these functions are appropriate for acute and episodic health problems, they cannot be applied to the prevention and management of chronic conditions. Preventive healthcare need a different approach.
