1) Healthcare demand is rising due to increasing rates of preventable illness and suboptimal use of healthcare resources influenced by consumer choices. Obesity rates in the US have led to increased chronic diseases and healthcare costs. 2) Healthcare demand differs from other services in that health outcomes cannot be standardized, consumers have limited choice in providers, and payment usually comes from third parties rather than consumers directly. 3) Consumers do not always make rational decisions regarding healthcare. They may seek emergency care for minor issues, be overwhelmed by excessive insurance options, or rely too heavily on provider recommendations without understanding implications.
