What Low Means
Low HDL is an independent risk factor for cardiovascular disease. Associated with metabolic syndrome, insulin resistance, and increased inflammation.
Possible Symptoms
No direct symptoms; increases silent cardiovascular risk
Risk Factors
Cardiovascular disease risk when low; metabolic syndrome
