The population is aging rapidly worldwide and as this occurs, the rate of
surgical procedures in older people is increasing in conjunction with the required
anesthesia services. Along with increased life expectancy, the disease burden is also
expanding with advanced medical care. This chapter will explore the extent of
worldwide aging demographics, the mechanics of aging, health care costs specific to
geriatrics, and the significance of anesthetic considerations in a rapidly aging world.
Keywords: Geriatric population, Life expectancy, Demographics, Mechanics of Aging, Healthcare costs.
