What is the primary purpose of preventive services in health care?

The primary purpose of preventive services in health care is to prevent illnesses or detect health issues early. Preventive services are designed to identify potential health problems before they develop into more serious conditions. This includes screenings, vaccinations, and counseling aimed at reducing the risk of diseases. By focusing on prevention, these services can lead to better health outcomes, lower healthcare costs over time, and can ultimately contribute to increased longevity.

In the context of the other options, elective surgeries are typically performed to address conditions that have already developed, rather than to prevent them. Managing chronic diseases involves addressing existing long-term health issues rather than preventing new ones. Promoting physical fitness is an important aspect of overall health but falls more under wellness and lifestyle choices rather than the direct aims of preventive health services.
