What is the normal level for LDL cholesterol?

The normal level for LDL (low-density lipoprotein) cholesterol is indeed considered to be less than 100 mg/dL. LDL cholesterol is often referred to as "bad" cholesterol because high levels can lead to plaque buildup in arteries, increasing the risk of cardiovascular diseases such as heart attacks and strokes.

Levels of LDL cholesterol are categorized as follows:

• Optimal: Less than 100 mg/dL
• Near optimal/above optimal: 100-129 mg/dL
• Borderline high: 130-159 mg/dL
• High: 160-189 mg/dL
• Very high: 190 mg/dL and above

Understanding these ranges is important for assessing cardiovascular risk and managing patient health. Clinicians often aim to keep LDL levels below 100 mg/dL, particularly in patients with known risks for heart disease. Thus, the designation of less than 100 mg/dL as the optimal level is grounded in clinical guidelines aimed at promoting cardiovascular health.
