Although cholesterol is one of the main components of blood lipids, when cholesterol increases, it is easy to be deposited on the arterial wall, leading to atherosclerosis. The main factors causing elevated blood lipids are: genetic factors, dietary factors, obesity, smoking, physical inactivity, excessive alcohol consumption, mental stress and so on. Blood lipids such as cholesterol and other increases, generally no obvious symptoms, found that increased blood lipids, and there is no clear reason, mostly related to genetic and family factors. Precautions: 1, dietary regulation: this is the most important and effective way to prevent and control high blood lipids. 1) Eat low-fat food: such as oatmeal, beans (such as soymilk, tofu, soybeans), fish and a variety of lean meat, milk, etc., especially eat more vegetables containing more fiber, can reduce the absorption of cholesterol in the intestine. Eat less high-fat food, such as poultry and eggs (especially egg yolks), fatty meat, animal offal, animal oil, etc. 2) Reduce the intake of sweets or carbohydrates: eating too much sweets or carbohydrates (such as rice and pasta) can be converted to triglycerides in the liver, causing an increase in endogenous triglycerides in the plasma. 3) Enhance physical activity and exercise: exercise can enhance the metabolism of the organism, which is conducive to the transport and decomposition of triglycerides. 4) Reduce the intestinal cholesterol intake. Reduce body weight: Obesity is an important factor causing elevated blood lipids, and people whose body weight exceeds the normal standard should gradually reduce their body weight. 5. Quit smoking and drink less alcohol: Alcoholism or long-term alcohol consumption can stimulate the liver to synthesize more endogenous triglycerides, which can increase the concentration of low-density lipoproteins in the blood and lead to hypercholesterolemia. 6. Avoid overstimulation: Emotional tension and over-excitement can cause blood cholesterol and triglycerides to increase. 7. It can cause blood cholesterol and triglyceride content to increase. For those who are ineffective in the above life and diet regulation, you can use some lipid-lowering drugs under the guidance of the doctor, such as selecting lipids Kang, or lipitor tablets and other Chinese medicinal preparations, generally with fewer side effects than the Western medicine, can be chosen.
