Preventive medicine is the branch of medicine that focuses on preventing disease and promoting health. It involves taking steps to prevent illness before it occurs, rather than treating it after it has already developed.
It is based on the principle that it is easier to prevent a disease than to treat it once it has developed.
There are many different types of preventive medicine, including vaccinations, lifestyle changes, and screenings. Vaccinations help to protect against diseases such as measles, mumps, and rubella. Lifestyle changes, such as eating a healthy diet and getting regular exercise, can help to prevent conditions such as obesity and heart disease.
Screenings are used to detect diseases in their early stages, when they are most treatable. Preventive medicine plays an important role in keeping people healthy and should be a part of everyone's healthcare routine.
