What Is LDL Cholesterol

According to the National Institutes of Health, LDL stands for low-density lipoprotein. This is otherwise known as the "bad" cholesterol because too much of it can cause cardiovascular diseases, or diseases that affect the heart and major blood vessels.

Why Is LDL "Bad" Cholesterol

LDL is called the "bad" cholesterol because in excess it forms deposits on the walls of the arteries, called plaque buildup. The more plaque builds up on the arteries, the less flexible and the more narrow they become, forcing the heart to work harder to pump blood, according to the American Heart Association.

LDL Calculated Ranges

When cholesterol tests are done, the ideal range for LDL cholesterol is less than 100 mg/dL, and even less (70mg/dL) for people with a history of heart disease in their families. Between 100 and 129mg/dL is within a normal range, according to the National Institutes of Health (NIH).

High LDL and Other Risk Factors

If your calculated LDL is higher than the normal range and you have either a history of heart problems in your family, high blood pressure, diabetes or are a smoker, then you are in the high-risk category for developing cardiovascular disease, the NIH reports.

Triglycerides and Cholesterol

According to the American Heart Association, there is a link between triglycerides and high total cholesterol (and high LDL, typically). Triglycerides are a type of fat that can be due to genetics or an underlying condition, but more often than not are due to living a sedentary lifestyle, being overweight or obese, and eating diet high in carbohydrates and fats.

Reduce Calculated LDL

The best way to reduce LDL is through lifestyle changes. A heart-healthy diet rich in fiber, antioxidants, lean proteins and less dietary cholesterol is important, as is incorporating exercise into your daily regimen.
