Understanding High LDL Cholesterol Levels

LDL (Low-Density Lipoprotein) cholesterol is often called “bad” cholesterol because it can build up in your arteries and form plaque. High LDL levels (above 130 mg/dL) increase your risk of heart disease and stroke.

What is Considered High?

An LDL cholesterol level above 130 mg/dL is considered high. The severity is categorized as follows:

  • Borderline high: 130-159 mg/dL
  • High: 160-189 mg/dL
  • Very high: ≥190 mg/dL
