Monitoring cholesterol levels is significant for maintaining cardiovascular health and preventing heart disease. High levels of LDL (bad cholesterol) can lead to arterial plaque buildup, increasing the risk of heart attacks and strokes. Conversely, high levels of HDL (good cholesterol) help remove excess cholesterol from the bloodstream. Regular check-ups can detect abnormal cholesterol levels early, allowing for lifestyle adjustments, such as improved diet and increased physical activity, or medical interventions when necessary. Through proactive monitoring, individuals can enhance their heart health and reduce the risk of associated diseases.
