From the Guidelines

Hyperlipidemia is primarily caused by a combination of genetic, acquired, and lifestyle factors.

Causes of Hyperlipidemia

  • Genetic disorders: Such as lipoprotein lipase deficiency, apolipoprotein CII deficiency, and familial hypertriglyceridemia 1
  • Acquired disorders of metabolism: Including hypothyroidism, poorly controlled insulinopenic diabetes, and renal disease 1
  • Diet and lifestyle: Excessive alcohol consumption, high saturated fat diet, and obesity 1
  • Drugs and medications: Certain medications such as antipsychotics, beta-blockers, and steroids can increase triglyceride levels 1
  • Diseases: Such as autoimmune chylomicronemia, chronic idiopathic urticaria, and certain types of cancer 1

Secondary Causes of Hypertriglyceridemia

It is essential to investigate and treat secondary causes of hypertriglyceridemia, including diseases, diet and lifestyle, drugs, and disorders of metabolism 1. Poor glycemic control in patients with diabetes mellitus can significantly exacerbate hypertriglyceridemia 1. Genetic predisposition to hypertriglyceridemia increases the likelihood and severity of elevated triglycerides in each category 1.

Importance of Identifying Causes

Identifying the underlying causes of hyperlipidemia is crucial for effective management and treatment. A combination of therapeutic lifestyle changes and pharmacological therapy may be necessary to reduce triglyceride levels and prevent associated complications such as pancreatitis and cardiovascular disease 1.

From the Research

Causes of Hyperlipidemia

  • Hyperlipidemia can be caused by a combination of genetic and environmental factors, including diet, drugs, disorders of metabolism, and diseases 2, 3
  • Genetic factors can play a significant role in the development of hyperlipidemia, with over 60% of the variability in serum lipids estimated to be genetically determined 4
  • Environmental factors such as diet and drug therapies can also increase the risk of hyperlipidemia, particularly when combined with genetic predisposition 2, 3
  • Certain medical conditions, such as hypothyroidism, can also contribute to the development of hyperlipidemia 2

Specific Causes

  • Diet: a diet rich in saturated fats and cholesterol can contribute to mild hypercholesterolemia, while alcohol excess and weight gain can lead to hypertriglyceridemia 2
  • Drugs: certain medications, such as glucocorticoids, estrogens, and anabolic steroids, can alter lipid profiles and increase the risk of hyperlipidemia 2
  • Disorders of metabolism: conditions such as familial hypercholesterolaemia and familial type III hyperlipoproteinaemia can increase the risk of hyperlipidemia 4
  • Diseases: certain diseases, such as hypothyroidism, can contribute to the development of hyperlipidemia 2

Risk Factors

  • Genetic predisposition: a family history of hyperlipidemia can increase an individual's risk of developing the condition 4
  • Environmental factors: exposure to certain environmental factors, such as a diet high in saturated fats and cholesterol, can increase the risk of hyperlipidemia 2, 3
  • Medical conditions: certain medical conditions, such as hypothyroidism, can increase the risk of hyperlipidemia 2
