Low-density cholesterol is called low-density lipoprotein in clinical medicine, and there are many causes of its high index, which are mainly divided into two situations, one is the irrational diet structure and the other is the influence of genetic factors. LDL is a lipoprotein particle that carries cholesterol to the peripheral tissues of the human body, and its elevation can easily lead to atherosclerosis of blood vessels. 1. Dietary structure: irregular daily diet, long-term consumption of greasy food, such as fried food containing a high concentration of trans fatty acids, which will cause LDL to rise. 2. Genetic factors: genes also play a role in the generation and transportation of LDL in human blood. If LDL is found to be elevated, it is recommended to go to the hospital, take medication regularly under the guidance of a physician, and consult a doctor if there is any discomfort in order to avoid delaying the condition.
