Normal value of low-density lipoprotein and reasons for high value

Low-density lipoprotein is a laboratory data. We know that cholesterol exists in the form of lipoprotein in the blood, and low-density lipoprotein is the main carrier for transporting cholesterol. If it is too high or too low, it will induce some symptoms. For example, when it is too high, it is easy to cause atherosclerosis, induce coronary heart disease, and myocardial infarction.

1. Normal value of LDL-C

The average for young people is about 2.7mmol/L (105mg/dl);

About 3.37mmol/L (130mg/dl) for middle-aged and elderly people;

Greater than 4.14mmol/L (>160mg/dl) is considered significantly elevated.

2. Causes of high LDL-C

Many factors can cause high LDL levels, which can be divided into two categories: non-pathological factors and pathological factors:

1. Non-pathological factors

(1 ) Unbalanced diet and excessive fat intake.

(2) High blood sugar levels caused by smoking and drinking.

(3) Overweight and obese people are more likely to have high levels of low-density lipoprotein.

2. Pathological factors

(1) Patients with abnormal liver function or hepatitis

(2) Atherosclerosis, hypertension, and cardiovascular diseases. Low-density lipoprotein can carry cholesterol into the cells of the human arterial wall. When low-density lipoprotein is higher than normal, excess cholesterol accumulates in the blood vessel wall, forming atherosclerosis and even coronary heart disease.
