1 What do you mean by high cholesterol? Hypercholesterolemia, also known as hypercholesterolemia, refers to a symptom of high low density lipoprotein cholesterol or low high density lipoprotein cholesterol in blood. Because human cholesterol is divided into high-density cholesterol and low-density cholesterol, the former has a protective effect on the cardiovascular system, which is usually called "good cholesterol", while the latter is high, and the risk of coronary heart disease will increase, which is usually called "bad cholesterol".

The normal range of adult total cholesterol is 2.86 ~ 5.98 mmol/L. If the serum cholesterol level is higher than this range, it means that the total cholesterol is high. So what is the reason for high cholesterol?

1, age factor. The serum total cholesterol level increases with age, but generally decreases after 70 or 80 years old. Before and after menopause, women have more chances to suffer from hyperlipidemia than other periods.

3. Dietary factors. Long-term intake of high saturated fatty acids and high calorie diet will lead to an increase in serum total cholesterol levels, and people who like to eat animal fat or cholesterol-rich foods on weekdays are also prone to increase serum total cholesterol levels.

4. Genetic factors. The level of cholesterol in the blood can be regulated by genes. For example, people with family hereditary diseases such as hypercholesterolemia and familial mixed hyperlipidemia have elevated serum total cholesterol.

5. Secondary diseases. Some secondary diseases, such as sick syndrome, hypothyroidism, diabetes, gout, hepatobiliary and pancreatic diseases, etc., will also increase cholesterol levels.

6. Other factors. Other factors that can lead to elevated cholesterol levels include lack of exercise and physical labor, smoking, and long-term mental stress.
