Dyslipidemia is an abnormal amount of lipids (fats) in the blood. ^[1] It is divided into six types which result in some combination of high total cholesterol, high LDL cholesterol, low HDL cholesterol, high triglycerides, or high apolipoprotein B. ^[1] There are generally no symptoms, though occasionally yellowish lipid deposits within the skin occur. ^{[1] [2]} Complications may include heart disease, stroke, and pancreatitis. ^{[1] [2]}

Causes may include poor diet, inactivity, obesity, excessive alcohol, and smoking. ^{[1] [2]} Other health conditions that can result in dyslipiedmia include diabetes, nephrotic syndrome, biliary obstruction, hypothyroidism, and certain medications. ^{[1] [2]} Some types run in families such as familial hypercholesterolemia. ^[1] Diagnosis is generally by blood tests for total, LDL, and HDL cholesterol, and triglycerides. ^[1]

Treatment involves lifestyle changes including a diet high in vegetables and exercise. ^[1] Other treatments depend in part on the types of dyslipidemia. ^[2] If medications are used, the initial choice is generally a statin. ^[1] Dyslipidemia becomes more common with age. ^[1] In the United States high cholesterol affects about 34% of those over the age of 20. ^[1]
