Understanding Low HDL Cholesterol Levels

HDL (High-Density Lipoprotein) cholesterol is known as “good” cholesterol because it helps remove other forms of cholesterol from your bloodstream. Low HDL levels (below 40 mg/dL in men or below 50 mg/dL in women) can increase the risk of heart disease.

What is Considered Low?

HDL cholesterol levels are considered low when they fall below:

  • Men: Less than 40 mg/dL
  • Women: Less than 50 mg/dL
  • High-risk: Less than 35 mg/dL (for both genders)
