Cholesterol is a substance that can be found in our bodies. The role of this substance is to help production of vitamins, hormones and insulate nerve fibers. Still, high levels of cholesterol in the blood can lead to cardiovascular diseases. This is why it is essential to maintain proper cholesterol levels in the blood.
Types of Cholesterol
We can measure the cholesterol level just by taking blood sample from a person, because cholesterol is distributed through our body via blood. Cholesterol is produced by the liver, and also, we can obtain this substance from the food. Lipoproteins are substances that can be found in the blood. They help distribution of the cholesterol through the circulatory system. There are two types of cholesterol, depending on the chemical composition of lipoproteins. These two types are: LDL – or Low Density Lipoproteins, and HDL – or High Density Lipoproteins. The LDL is also known as “bad cholesterol”, and it is responsible for the accumulation of cholesterol in the arteries, and hence narrowing the arteries. On the other hand, HDL circulates the unexploited cholesterol from the body to the liver. So, it is obvious that low levels of LDL and high levels of HDL in the body are desirable.
About Normal Cholesterol Range
Cholesterol levels, in the blood test reports are presented in milligrams per deciliter (mg/dl) of blood. That actually means how much milligrams of cholesterol is presented in a deciliter of blood. On this report, we can find three numbers: first represents the total cholesterol level, second HDL level and third is LDL level. Of course, there are prescribed normal cholesterol levels, as well. Keeping your cholesterol levels under the critical level lowers risk of being affected by some kind of cardiovascular disease.
Healthy cholesterol ranges are: total cholesterol – less than 200 mg/dl; HDL – 60 mg/dl and more; LDL – less than 100 mg/dl. Borderline cholesterol ranges are: for total cholesterol – less than 200 to 239 mg/dl; for HDL – 40 to 50 for male and 50 to 60 mg/dl for female mg/dl; for LDL – between 130 and 159 mg/dl. High risk cholesterol ranges are: total cholesterol – 240 mg/dl and more; HDL – under 40 for male, and under 50 for female mg/dl; and for LDL – from 160 to 189 mg/dl is considered as high, and from 190 mg/dl and above is considered as very high..This is some basic information on the cholesterol level. It is important to keep your cholesterol under control.
