  6. 6. Biomedical theory ● Traditionally health has been viewed as "absence of disease" if one person is free from disease, s/he is considered as healthy. This concept is known as "Biomedical Concept", it has basis in germ theory of disease. ● The medical profession viewed the human body as a machine, disease because of the breakdown of the machine and one of the Doctor's tasks as repair of machine. ● The limitation of this concept is that, it has minimized the role of environmental, social, psychological and cultural determinants of health.
  7. 7. Ecological theory ● The ecologist put forward another hypothesis, which viewed health as a dynamic equilibrium between man and his environment, and disease as a maladjustment of the human organisms to the environment. ● Ecological and cultural adaptations determine not only the occurrence of disease but also the availability of food and the population explosion. ● The concept supports the need for clean air, safe water, ozonic layer in the atmosphere, etc. to protect us from exposure to unhealthy factors.
  8. 8. Psychosocial well being Contemporary developments in social sciences revealed that health is not only a biomedical phenomenon, but also one, which is in the need by social psychological, cultural, economic and political factors of the people concerned. Health is both a biological and social phenomenon.
  9. 9. Holistic theory ● Holism means viewing a person's health as a balance of body, mind, and spirit. Treating only the body will not necessarily restore optimal health. In addition to physical needs, nurses must also consider clients' psychological, sociocultural, developmental, and spiritual needs. ● Holistic model is a synthesis of biomedical & ecological model & psychosocial concept. It recognizes the strength of social, economic, political and environmental influence on health.
