Dyslipidemia refers to abnormal levels of cholesterol and/or triglycerides in the blood. It often causes no symptoms but can increase long-term cardiovascular risk and, in some cases of very high triglycerides, raise the risk of pancreatitis. Below are causes, common tests, lifestyle measures that help, and which specialties may be involved. If you have acute warning signs—chest pain, sudden breathlessness, new weakness or speech problems—seek emergency care immediately.
What dyslipidemia is and common types
Dyslipidemia covers various departures from normal lipid levels: high LDL (“bad”) cholesterol, low HDL (“good”) cholesterol, elevated total cholesterol, and high triglycerides. Causes include genetic conditions (for example familial hypercholesterolemia), metabolic disorders, some medications, excessive alcohol use, and endocrine or kidney diseases that affect lipid metabolism.
Who is at higher risk and possible complications
Risk increases with type 2 diabetes, obesity, smoking, sedentary lifestyle, excessive alcohol intake, and a family history of early heart disease. Over time, abnormal lipids contribute to atherosclerosis and raise the chance of heart attack and stroke. Very high triglyceride levels can, rarely, be associated with pancreatitis. Individual risk is assessed together with other factors such as age, blood pressure and blood sugar.
Diagnosis and common tests
Diagnosis is usually based on a blood lipid panel measuring total cholesterol, LDL, HDL and triglycerides. Tests may be performed fasting or non‑fasting depending on practice; clinicians may also order apolipoprotein B, calculated LDL variants, glucose, thyroid, liver and kidney function tests to clarify causes. Cardiovascular risk calculators help determine follow‑up and need for specialist input.
Lifestyle changes and prevention
Dietary adjustments—reducing saturated and trans fats, increasing fiber and whole foods, and limiting refined sugars—can improve lipid profiles. Regular physical activity, maintaining a healthy weight, quitting smoking and limiting alcohol are important. These measures support overall cardiovascular health; the optimal plan depends on individual risk and should be reviewed with a clinician.
