Hyperlipidemia belongs to a group of chronic diseases that are characterized by higher than normal plasma lipids such as total cholesterol, low-density lipoprotein and/or triglycerides. There are many causes of hyperlipidemia, and different types of hyperlipidemia have different causative factors.
I. Causes of hyperlipidemia
Hyperlipidemia is mainly divided into primary hyperlipidemia, secondary hyperlipidemia and others, and its causes are as follows.
1, primary hyperlipidemia: mostly related to genetic factors, due to single gene defects or multiple gene defects, so that the receptors, enzymes or apolipoproteins involved in lipoprotein transport and metabolism are abnormal.
2.Secondary hyperlipidemia: mostly occurs in metabolic disorders such as diabetes, hypertension, hypothyroidism, liver and kidney diseases, obesity, hyperadrenocorticism, etc. There are also drug factors such as sex hormone preparations, steroid hormone preparations, etc., which can also cause the disease.
3.Other types of hyperlipidemia
(1) Improper diet: high-fat food, sweets, excessive intake of refined processed rice and noodles, etc.
(2) non-exercise or insufficient exercise: long-term non-exercise, sedentary, long lying, are not conducive to the removal of lipids in the blood plasma;?
(3) Smoking and alcohol abuse: long-term smoking and alcohol abuse will affect human immunity and cell secretion, which in turn will lead to mental anxiety and other bad emotions and more likely to induce hyperlipidemia.
Second, the susceptible group of hyperlipidemia
In general, hyperlipidemia can occur in people of any age, but the following groups are more likely to suffer from.
1, patients with family history of hyperlipidemia.
2.Patients with hypertension, diabetes and fatty liver.
3, long-term smokers and alcoholics.
4, obese people.
5, middle-aged and elderly (men ≥ 45 years old women ≥ 55 years old)
6, postmenopausal women.
7, lack of exercise.
8, long-term high-fat, high-sugar diet.
9, patients with cardiovascular disease.
Third, what are the signs of high blood lipid
There are certain signs of elevated blood lipids, once you find yourself in the following performance, it is recommended to go to the hospital to check the blood lipid level.
1, corneal age ring: that is, the appearance of round white or yellowish ring-shaped spots around the cornea.
2, yellow tumor: preferably in the hands, feet, buttocks, oral cavity, generally orange or brownish yellow, mildly raised, round nodules.
3, lipidemia fundus: that is, small arteries in the fundus of the eye yellow-white changes.
Fourth, how to properly lower blood lipids
Once elevated blood lipids are found, it is recommended that diet and exercise adjustments are the mainstay to promote recovery of blood lipid levels. Diet is recommended to be low salt, low fat, low sugar and high fiber diet, such as limiting sodium and salt intake, eating less pickled products, less animal offal and fatty meat, less refined rice and white flour, desserts and sugary drinks, and quitting smoking and limiting alcohol; secondly, reasonable exercise is recommended, insisting on moderate intensity aerobic exercise for more than 30 minutes daily, no less than 3-5 times a week. If life method intervention is not satisfactory, lipid-lowering drugs, such as statins, betablockers and niacin lipid-lowering drugs, can be used under the guidance of doctors.
