Hyperlipidemia is a condition marked by elevated blood lipids, increasing the risk of heart disease, stroke, and atherosclerosis.
- Hyperlipidemia refers to elevated levels of lipids (fats) in the blood, including cholesterol and triglycerides.
- It is a significant risk factor for the development of cardiovascular diseases.

Types of Lipids Involved:
- Low-Density Lipoprotein (LDL) Cholesterol: Often termed “bad” cholesterol; high levels can lead to plaque buildup in arteries.
- High-Density Lipoprotein (HDL) Cholesterol: Known as “good” cholesterol; helps remove LDL cholesterol from the bloodstream.
- Triglycerides: Elevated levels can contribute to atherosclerosis and pancreatitis.
Causes of Hyperlipidemia:
- Genetic Factors: Familial hypercholesterolemia.
- Diet: High intake of saturated fats, trans fats, and cholesterol.
- Lifestyle: Sedentary behavior, obesity, and excessive alcohol consumption.
- Medical Conditions: Diabetes, hypothyroidism, and kidney disease.

Symptoms of Hyperlipidemia:
- Often asymptomatic; typically detected through blood tests.
- In severe cases, can lead to symptoms of cardiovascular diseases like chest pain or stroke.
Complications:
- Atherosclerosis: Hardening and narrowing of arteries.
- Cardiovascular Diseases: Increased risk of heart attacks, strokes, and peripheral artery disease.

Management:
- Lifestyle Modifications: Healthy diet, regular exercise, weight management, and smoking cessation.
