Understanding Cholesterol Ratios
The total cholesterol to HDL ratio is a key indicator of cardiovascular health. It compares your total cholesterol — which includes LDL (bad) cholesterol, HDL (good) cholesterol, and other lipid components — against your HDL level. Because HDL helps remove excess cholesterol from your bloodstream, a higher HDL generally leads to a better ratio and lower heart disease risk.
| Ratio Range | Risk Level |
|---|---|
| < 3.5 | Optimal |
| 3.5 — 5.0 | Borderline |
| > 5.0 | High Risk |
Good vs Bad Cholesterol
HDL — Good Cholesterol
High-Density Lipoprotein (HDL) acts like a scavenger, picking up excess cholesterol from your bloodstream and carrying it back to your liver for disposal. Higher HDL levels are associated with a lower risk of heart disease and stroke.
LDL — Bad Cholesterol
Low-Density Lipoprotein (LDL) transports cholesterol particles throughout your body, where they can build up in artery walls and form plaques. High LDL levels increase the risk of atherosclerosis, heart attacks, and strokes.
