National Cholesterol Education Month

National Cholesterol Education Month is observed throughout September as a time to learn more about cholesterol and its important role in heart health. The observance encourages people to understand the difference between HDL (“good”) and LDL (“bad”) cholesterol, recognize risk factors, and talk with a healthcare professional about appropriate testing and personal health goals.

Throughout the month, individuals and families are invited to make heart-healthy choices, such as enjoying a balanced diet, staying physically active, avoiding tobacco, and taking prescribed medications as directed. By building awareness and making informed decisions, National Cholesterol Education Month helps empower people to take meaningful steps toward protecting their cardiovascular health.

National Cholesterol Education Month is observed throughout September to promote awareness of cholesterol, its relationship to cardiovascular disease, and the importance of regular screening. Its modern history is closely connected with the National Cholesterol Education Program (NCEP), launched by the National Heart, Lung, and Blood Institute in 1985. The program was created in response to strong evidence that high levels of blood cholesterol—particularly low-density lipoprotein (LDL) cholesterol—contribute to atherosclerosis, heart attack, and stroke. By bringing together government agencies, medical professionals, public-health organizations, and community groups, the initiative sought to make cholesterol education a national health priority.

In its early years, the campaign emphasized identifying adults with elevated cholesterol and encouraging dietary changes, physical activity, and other heart-healthy habits. NCEP materials also helped establish more consistent approaches to testing and treatment in doctors’ offices. The Adult Treatment Panel issued influential recommendations beginning in the late 1980s, followed by updated guidance in 1993 and the widely used Adult Treatment Panel III report in 2001, with a major update in 2004. These efforts helped shift public understanding away from cholesterol as a single, simple number and toward a broader assessment of LDL cholesterol, high-density lipoprotein (HDL) cholesterol, triglycerides, family history, diabetes, smoking, blood pressure, and other cardiovascular risks.

Over time, cholesterol education has evolved alongside medical research. Public-health messaging increasingly stresses that cholesterol problems can affect people without obvious symptoms, making screening and discussions with health professionals important. It also recognizes that inherited conditions such as familial hypercholesterolemia may cause very high cholesterol even when a person follows a healthy lifestyle. More recent prevention strategies place greater emphasis on overall cardiovascular risk, shared decision-making, nutrition, regular exercise, weight management, and appropriate use of cholesterol-lowering medicines rather than treating every individual according to a single threshold.

The observance has cultural significance because it turns a complex medical topic into an annual opportunity for public discussion. Throughout September, health-care providers, schools, employers, pharmacies, and community organizations may distribute educational materials, encourage cholesterol checks, and promote heart-healthy behaviors. Its continuing importance reflects the enduring burden of cardiovascular disease and the fact that high cholesterol often produces no warning signs. National Cholesterol Education Month therefore connects the history of preventive medicine with an ongoing effort to make reliable health information and early risk reduction part of everyday life.
