The elderly represent a vulnerable and sensitive age group whose share is slightly increasing. Thus, there is a need for a comprehensive approach in protecting the health of the elderly. Everyday new knowledge about the aging process leads to the thesis that gerontology as a scientific discipline will have an important place in developed countries in the world. The term of gerontology itself, means an interdisciplinary science of the aging process, and geriatrics as a branch of medicine is used fordiagnosis, treatment, rehabilitation and disease prevention in the elderly. As a person ages, changes occur in each individual's body: from changes in the skin, face, bones, muscles, changes in the heart, blood vessels and respiratory organs to changes in the urinary and digestive systems, endocrine and reproductive systems, and changes in hearing and vision.In old age, in addition to physiological changes in the structure of organs and organ systems, there are psychological changes, changes in lifestyle and social roles and relationships, and acceptance and adaptation to the new "period of life" and present changes is described through theories of geriatric health care.
