Cholesterol is a type of fat found in the blood, essential for producing hormones, vitamin D, and substances that help digest food. Monitoring cholesterol levels is crucial as high levels of LDL (bad cholesterol) can lead to heart disease and stroke by causing arterial blockages. Conversely, HDL (good cholesterol) helps remove LDL from the blood. Regular health checks can identify imbalances, prompting lifestyle changes or interventions. Awareness of cholesterol levels promotes heart health, supporting overall well-being and reducing the risk of cardiovascular issues.
