What Is Cholesterol and What Does It Do?
Cholesterol is a waxy, fat-like substance that plays an important role in your body. It helps build healthy cells, supports hormone production, and aids in making vitamin D. Your liver produces all the cholesterol your body needs, but it can also come from animal-based foods such as meat, eggs, and dairy products.
Foods high in saturated and trans fats can cause your liver to produce extra cholesterol. While it is essential, having too much circulating in the blood can increase the risk of serious health problems.
Understanding How Cholesterol Moves Through the Body
Cholesterol does not travel through the bloodstream on its own. Instead, it is carried by proteins called lipoproteins. When blood lipid levels become unbalanced, can start to build up in the arteries, affecting blood flow and heart health.
HDL vs LDL: What’s the Difference?
There are two Types
HDL (High-Density Lipoprotein)
Often called good cholesterol, HDL helps remove excess cholesterol from the bloodstream and transports it back to the liver for removal. Higher HDL levels are associated with better heart health.
LDL (Low-Density Lipoprotein)
Known as bad cholesterol, LDL can stick to artery walls and form plaque. Over time, this buildup can narrow blood vessels and restrict blood flow.
Health Risks Linked to High LDL Levels
When LDL cholesterol remains elevated, it can contribute to several medical conditions, including:
-
Coronary artery disease
-
Carotid artery disease
-
Peripheral artery disease
-
High blood pressure
The Centers for Disease Control and Prevention (CDC) notes that uncontrolled and significantly increases the risk of heart attack and stroke.
Ways to Maintain Healthy Cholesterol Levels
Many issues can be improved—or prevented—through lifestyle changes, such as:
-
Quitting smoking: Helps raise HDL levels and improves overall heart and lung health
-
Eating a balanced diet: Focus on fruits, vegetables, whole grains, lean proteins, and soluble fiber
-
Limiting unhealthy fats: Reduce saturated and trans fats found in processed foods
-
Staying active: Regular physical activity helps control weight and improves lipid balance
-
Maintaining a healthy weight: Excess body fat can increase LDL levels
In some cases, lifestyle changes alone may not be enough. Your healthcare provider may recommend medications to help manage more effectively.
