Why checking your cholesterol could save your heart—and your life
Managing cholesterol plays a vital role in reducing the risk of heart disease and stroke. While it is only one of several factors, keeping levels in check can help prevent long-term health problems. Many people remain unaware of their cholesterol status, as high levels often show no symptoms until serious damage occurs.
A simple blood test called a lipid panel can measure key indicators: total cholesterol, LDL (low-density lipoprotein), HDL (high-density lipoprotein), and triglycerides. Doctors recommend healthy adults get tested every four to six years, starting at age 20. Children with a high risk of heart disease should also undergo screening.
The test is inexpensive and usually done at a fasting blood draw station, either in a clinical lab or a primary care clinic. Optimal results include total cholesterol below 200 mg/dL, LDL under 100 mg/dL, HDL above 60 mg/dL, and triglycerides under 150 mg/dL. When cholesterol levels fall outside the healthy range, doctors may suggest lifestyle changes or prescribe statins. These medications, combined with diet and exercise, can effectively lower high cholesterol. Without intervention, excess cholesterol builds up in blood vessels, restricting blood flow and increasing the risk of heart attacks or strokes.
Regular cholesterol checks and early action can help maintain heart health. Statins and lifestyle adjustments remain the most common treatments for high levels. By monitoring and managing cholesterol, individuals can reduce their long-term risk of cardiovascular disease.
