Step 3: What causes high cholesterol?
Next Page

Unhealthy cholesterol levels are linked to having a poor diet, lack of exercise, being overweight, age, heredity, and other factors.

Poor diet

The unhealthy foods most likely to raise your LDL cholesterol are those that contain saturated fat and trans-fatty acids.

Lack of exercise

Lack of physical activity can lead to high LDL cholesterol. On the other hand, regular exercise can increase good cholesterol, lower bad cholesterol, decrease your risk for heart disease, and improve your overall health.

Being overweight

Overweight people often don't have enough HDL (good) cholesterol, and their triglycerides are often too high. Their LDL (bad) cholesterol may be too high as well. Furthermore, obesity increases the risk for high blood pressure and type 2 diabetes, which put you at risk for developing heart disease.

Older age

Cholesterol levels tend to rise in both men and women as they get older. This is very important because heart disease is the number one cause of death for both men AND women:

Heredity

Genetics play an important role in determining your blood cholesterol level. Children and teens should have their cholesterol checked if family members have had either early heart disease or total cholesterol levels greater than 240 mg/dL. Early heart disease is defined as a father, brother, uncle, or grandfather who developed heart disease before age 55, or a mother, sister, aunt, or grandmother before age 65.
