Low-density lipoprotein, or LDL, is known as "bad" cholesterol, while high-density lipoprotein or HDL cholesterol is known as "good".
Both types of lipids, along with triglycerides and cholesterol Lp (a) establish the total amount of cholesterol measured in blood tests.
LDL cholesterol (Cholesterol Evil)
Levels of LDL (bad cholesterol) is too high in the blood, it can slowly lead to clogged arteries leading to the heart and brain.
LDL to form plaques, or walls that can narrow the arteries and make them less flexible.
This condition is known as atherosclerosis. If the narrowed artery, heart attack or stroke may occur.
HDL cholesterol (good cholesterol)
Approximately one-quarter to one-third of blood cholesterol is made up of high-density lipoprotein (HDL).
HDL cholesterol is known as "good" cholesterol, because high levels of HDL can protect against heart attacks.
Low levels of HDL (less than 40 mg / dL) may increase the risk of heart disease. HDL tends to carry cholesterol away from the arteries back to the liver.
Some experts believe that HDL function slowing arterial blockages.
triglycerides
Triglycerides are fats that are made in the body. Elevated triglycerides are caused by overweight / obesity, lack of exercise, smoking, excessive alcohol consumption and a diet very high in carbohydrates.
People with high triglycerides often have high levels of total cholesterol is too high, including high LDL levels and low HDL.
Many people with heart disease and / or diabetes also have high triglyceride levels.
Cholesterol Lp (a)
Lp (a) is a genetic variation of LDL cholesterol (bad). Levels of Lp (a) levels will increase the risk of fatty deposits in the arteries.
Lp (a) is not fully understood. Lp (a) could be expected to interact with substances found in artery walls and contribute to fat accumulation.
