On top of early detection of diseases, health screenings also identify health risks an individual may face in the future. Monitoring blood glucose levels through blood tests, for example, can detect a pre-diabetes state, which can help the individual kickstart a change in his lifestyle and diet to prevent diabetes onset later on.

Also, certain conditions may not show any signs and symptoms. Very often, individuals with high blood pressure may not feel any symptoms but the increase in blood pressure can stress out the heart and blood vessels. This eventually causes damage over time and can potentially lead to a heart attack or stroke. Health screenings and regular health check ups can help prevent this through early detection.
