Hyperlipidemia is a medical condition characterized by abnormally high levels of lipids (fats) or lipoproteins in the blood. These lipids include cholesterol, triglycerides, and phospholipids. The condition itself is a laboratory finding indicating elevated blood lipid levels and can stem from various genetic or acquired disorders. There are two main types of hyperlipidemia:

  • Primary hyperlipidemia , which is usually caused by genetic factors such as mutations in receptor proteins.
  • Secondary hyperlipidemia , which arises due to other underlying causes like diabetes, lifestyle factors (e.g., high-fat diet, inactivity, obesity), or certain medications.

Hyperlipidemia is a significant risk factor for cardiovascular diseases because excess lipids can form fatty deposits (plaque) in the blood vessels, leading to atherosclerosis (hardening of arteries). This can increase the risk of heart attack, stroke, and peripheral artery disease. There are specific types of genetic hyperlipidemias like familial hypercholesterolemia and familial hypertriglyceridemia, which affect cholesterol and triglyceride levels, respectively. Hyperlipidemia itself typically does not produce symptoms but may lead to symptoms of related conditions such as chest pain, high blood pressure, heart attack, or stroke. Management often involves lifestyle modifications like diet and exercise, and in many cases, medication is necessary to control the blood lipid levels. In summary, hyperlipidemia means having too much fat in the blood, increasing the risk of serious cardiovascular problems, and usually requires ongoing management to reduce these risks.
