Understanding Good and Bad Cholesterol: A Crucial Step Toward Heart Health

High cholesterol is a common but serious health concern impacting millions of Americans. According to the Centers for Disease Control and Prevention (CDC), about 38 percent of adults in the United States have high cholesterol, a condition that significantly increases the risk of heart disease and stroke—two of the leading causes of death in the country. Understanding cholesterol and how to manage it is key to helping maintain heart health.

“Cholesterol is a compound that’s essential for our body’s function,” says Deon Regis, MD, a primary care physician who treats patients at Mercy Health – Oberlin Primary Care. “It helps build cell membranes, produce hormones, and aid in digestion. However, not all cholesterol is created equal, and distinguishing between the good and the bad is vital for reducing your risk of cardiovascular disease.”

Cholesterol is categorized into two types:

  • High-Density Lipoprotein (HDL): Known as “good” cholesterol, HDL helps remove other forms of cholesterol from the bloodstream. Higher levels of HDL are linked to a lower risk of heart disease.
  • Low-Density Lipoprotein (LDL): Often referred to as “bad” cholesterol, LDL can contribute to the buildup of fatty deposits in the arteries, leading to heart attacks and strokes.

While cholesterol is partly produced by the body, about 20 percent comes from the food we eat. Mercy Health providers recommend a heart-healthy diet to help manage cholesterol levels. “I advise my patients to focus on a diet low in saturated fat and rich in fruits, vegetables, and healthy fats, like olive oil,” says Dr. Regis. “Incorporating foods like whole grains, lean proteins, and fiber-rich fruits and vegetables can lower LDL cholesterol and provide other heart benefits.”

In addition to diet, exercise and physical activity is key to raising HDL and lowering LDL cholesterol levels. Mercy Health providers recommend at least 150 minutes of moderate intensity exercise each week, such as brisk walking or cycling. The goal is to make exercise an integral part of your lifestyle.

When Diet and Exercise Aren’t Enough

For some individuals, genetic factors may lead to high cholesterol levels that cannot be managed by diet and exercise alone. In these cases, medication might be necessary. “Statins are the most commonly prescribed drugs for lowering cholesterol,” says Dr. Regis. “They are highly effective, although some patients may experience side effects. For most individuals, the benefits far outweigh the risks, particularly for those at high risk for heart disease.”

The Importance of Routine Screening

High cholesterol is often referred to as a silent condition because it typically does not present symptoms until significant damage has occurred. Routine screening is critical for early detection and management of high cholesterol. It is key to discuss with your healthcare provider how often you should be screened based on your personal risk factors.

By understanding the differences between good and bad cholesterol and taking a proactive approach to managing your cholesterol levels, you can significantly reduce your risk of heart disease and stroke. Consult with your healthcare provider to develop a personalized plan that fits your health needs.
