What is a good cholesterol?

Cholesterol is a greasy substance that is a by -product of normal liver metabolism. While many people are only concerned about the word, cholesterol is actually necessary for a number of biological processes. For example, the body requires cholesterol for the production of vitamin D. It is also needed to produce bile acid to support proper digestion and production of androgenic hormones. However, there is a key difference between good cholesterol and poor cholesterol.

Because different cells use cholesterol, they must be transported through blood circulation to get where it is needed. This is especially true because cholesterol is insoluble in the blood. The vehicle comes in the type of lipid called lipoprotein. Lipoproteins are marked as either low density or high density. Good cholesterol is also known as HDL cholesterol, because its transport method comes from lipoproteins with high density. On the other hand, bad cholesterol or LDL cholesterol Jeprojel Blood steam through LipoPrOTEINS with low density.

In addition to the way of transport, there is a difference in the finish between good cholesterol and poor cholesterol. Cholesterol LDL is considered "bad" because it generally never destroys from the bloodstream. In fact, it tends to circulate there. This allows cholesterol to collect in the arterial walls and finally form bearings of hard substances known as plaque. Because the arteries supply blood to the brain and heart, blocking or narrowing these routes can significantly increase the risk of heart attack or stroke.

Good cholesterol, on the other hand, is called as such because it is carried by high density lipoproteins. This is meaningful because HDL Lipids tend to transport cholesterol from arteries and return to the liver, where it is eventually eliminated as waste. In addition, LDL cholesterol on the left circulating in the bloodstream is often captured in the process before it has a chance to accumulate and create a plaque inTherenx. That is why greater concentration of good cholesterol serum is considered to be beneficial to reduce the risk of heart disease and other complications.

Blood cholesterol levels are checked by three values ​​measurement: LDL (poor cholesterol), HDL (good cholesterol) and triglycerides, another type of fat made of unused calories, which is also transported through low density lipoproteins. This blood test may first require several hours of fasting, otherwise it may not be possible to determine the levels of LDL cholesterol and triglycerides accurately. Whether and when to let your cholesterol control depends on various factors, including diet, lifestyle, medical history and age. In addition, high -risk factors for heart diseases such as smoking, excessive alcohol consumption, or high blood tlactesting esterol at earlier age, and with greater frequency afterwards, may require high -risk factors for heart diseases.
