In this modern world almost everyone is aware about cholesterol and the harmful effects of cholesterol on human body, but does everybody can differentiate between good cholesterol and bad cholesterol?? Don’t worry we are here to tell you the difference and functions of both good cholesterol and bad cholesterol on human body.
Cholesterol and its role in Human body:
We hear and read most often to avoid the food rich in cholesterol as a preventive measure against heart diseases, which is a good thing to keep in mind but not everybody knows that our body also make cholesterol for the proper functioning of body organs. Cholesterol is a waxy/ fat like substance responsible for the growth of body organs, some hormones, for the making of Vitamin D and bile production for digestion. Liver is the body organ which makes cholesterol and from here it is distributed to other body parts.
Good Cholesterol (HDL) and Bad Cholesterol (LDL):
Commonly we know that excess of everything is bad especially in terms of health, in the similar way excess of cholesterol is the major reason for heart diseases (coronary heart disease). Cholesterol attaches to a protein called lipoprotein which is then carried by blood to the body organs. Lipoprotein is actually the agent which makes the cholesterol transferable by blood. Two of the most known lipoproteins are LDL (Low Density Lipoprotein) and HDL (High Density Lipoprotein).
Low Density Lipoprotein LDL (Bad Cholesterol):
LDL (Low Density Lipoprotein) is considered as bad cholesterol and the excess of LDL in our body leads to coronary heart disease. The main function of LDL is to transfer cholesterol from liver to body cells where it is used in cell membrane and in the making of steroid hormones. High amount of LDL cholesterol results in narrowed blood vessels can result in complete blockage if not treated on time.
High Density Lipoprotein HDL (Good Cholesterol):
HDL is considered as good cholesterol by its function in the body. The function of HDL is reverse to the function of LDL. HDL is responsible for bringing back the excess cholesterol from cells and body parts to the liver. Liver and small intestine make and secrete HDL which circulates in the blood and gather cholesterol forming mature HDL, which results in bringing cholesterol back to the liver through different pathways. Liver then get rid of excess cholesterol by converting it to bile salts. Low HDL levels in body will also put you at risk of heart diseases.
What Levels of HDL and LDL are good for our Body:
For good and healthy heart and body LDL (Bad Cholesterol level) should not cross 100-129mg/dl limit, if it is below 100mg/dl it mains you are in good health. HDL (Good Cholesterol level) should not fall down this limit 40mg/dl, the higher the level of HDL the lower will be the risk of heart diseases.
How to know if body cholesterol is high:
There are no symptoms of high cholesterol until it starts damaging our body, blood test for cholesterol is the only way to put a check on this silent killer prior to let it seriously damage our body.
