The early signs and symptoms of high cholesterol in the blood are mainly clinical and can be seen in the results of routine laboratory testing. Later signs and symptoms include clogged arteries and a heart attack.
Considerations
Low-density lipoprotein (LDL) cholesterol is a component of total cholesterol and is known as "bad" cholesterol because it is the part that is responsible for worrisome symptoms, such as blocked arteries.
Identification
High total cholesterol as defined by the National Cholesterol Education Program (NCEP) is a blood level of 240 mg/dL or above. High LDL cholesterol is any level over 160 mg/dL.
Effects
Over time, excess LDL cholesterol in the blood can stick to the lining of artery walls and build up as plaque deposits in the arteries. These plaque deposits harden artery walls and block normal blood flow.
Potential
When combined with other risk factors, such as high blood pressure, smoking, overweight or family history of heart disease, the symptoms of high cholesterol may increase your risk of heart disease.
Strategy
To reduce the signs and symptoms of high cholesterol, the American Heart Association recommends consuming no more than 300 mg cholesterol from your diet if you are healthy, and no more than 200 mg if you are at risk of or have heart disease.
