HDL cholesterol 1.01μmmol/L is within the normal range and does not require treatment. The normal range of HDL cholesterol is 0.7~2.0μmmol/L. HDL cholesterol is mainly synthesized by the liver and the small intestine, and its main function is to transport cholesterol from extrahepatic tissues to the liver for re-circulation or excretion through bile acids, so as to reduce the accumulation of cholesterol in other tissues or the walls of blood vessels. Therefore, HDL cholesterol has anti-atherosclerotic effects and is beneficial to human health, so there is a negative correlation between HDL cholesterol and cardiovascular incidence. HDL cholesterol 1.01μmmol/L, in daily life, just need to pay attention to light diet, quit smoking and drinking, and maintain a regular routine life.
