Diabetes screening is a process used to identify individuals at risk of developing diabetes. It typically involves a simple blood test that measures blood sugar levels. Early detection is crucial because it allows for timely intervention, which can help prevent or delay the onset of type 2 diabetes and its complications. Screening is generally recommended for adults over a certain age or those with risk factors such as obesity, family history, or high blood pressure. Regular screening can help monitor glucose levels and guide lifestyle changes or treatments to maintain healthy blood sugar levels.
