The healthcare industry (also called the medical industry or health economy) is an aggregation and integration of sectors within the economic system that provides goods and services to treat patients with curative, preventive, rehabilitative, and palliative care. It includes the generation and commercialization of goods and services lending themselves to maintaining and re-establishing health. The health care industry is one of the largest and growing industries in the world and is an enormous part of a country’s economy. The healthcare sector includes publicly-traded companies that power all dimensions of the healthcare industry. These companies include, but are not limited to, biotechnology companies, health insurance providers, pharmaceutical companies, and companies that manage clinics and hospitals. Companies that produce professional and home health products (for example, blood-pressure monitors, elastoplasts, orthopedic devices, and surgical supplies) are also included in this sector.
