About Preventive Medicine


Preventive Medicine is the speciality of medical practice which focuses on the health of people, communities and defined populations. The aim of Preventive Medicine is to protect, promote and maintain health and well being and to prevent disease, disability and death.  Preventive medicine involves prevention of disease and promotion of health.

A doctor’s role is no longer confined to diagnosing and treating those who come to the hospital. He is also responsible for those who need his service to ensure that people do not go to the hospital. Health of the people is not only the concern of health care providers. It is the responsibility of the community also to identify and solve their own health problems through their active participation.

Preventive medicine or preventive care refers to measures taken to prevent diseases, rather than curing them or treating their symptoms.

Simple examples of preventive medicine are hand washing, breastfeeding and immunizations.  A person with a family history of cancers should begin screening at an earlier age.
