A cholesterol test returns several numbers that most people don't understand. Knowing what these numbers mean and how they affect heart health empowers better decisions.
Total Cholesterol
This combines all cholesterol types. Under 200 mg/dL is desirable. But total cholesterol alone doesn't tell the complete storyâthe breakdown matters more than the sum.
LDL: The "Bad" Cholesterol
LDL cholesterol contributes to plaque buildup in arteries. Lower is betterâunder 100 mg/dL is optimal. People with existing heart disease or high risk need even lower targets.
HDL: The "Good" Cholesterol
HDL helps remove cholesterol from arteries. Higher is betterâabove 60 mg/dL is protective. Low HDL (under 40 for men, under 50 for women) increases heart disease risk even with normal LDL.
Triglycerides
These blood fats from food energy storage indicate metabolic health. Under 150 mg/dL is normal. High triglycerides often accompany other cardiovascular risk factors.
Ratios Matter
Total cholesterol to HDL ratio provides insight beyond individual numbers. A ratio under 5:1 is desirable; 3.5:1 or below is optimal. This ratio sometimes reveals risk that individual numbers miss.
Lifestyle Impact
Diet, exercise, and weight significantly affect cholesterol. Reducing saturated fat, increasing fiber, exercising regularly, and maintaining healthy weight all improve cholesterol profilesâsometimes enough to avoid medication.
