The normal indicator of blood lipid is 0.45-1.7mmol/L, which is the normal value. If the blood lipid is greater than 1.7mmol/L, it is hyperlipidemia. There are many factors that cause hyperlipidemia, such as obesity, irregular diet, high-fat and high-salt diet, and genetic factors. General control of blood lipid can be treated by diet, such as less oil, less salt, low fat, do not eat animal offal, such as heart, kidney and other foods, as well as fatty meat, fried, barbecue and other foods, to eat more green vegetables as well as fruits. Exercise regularly, lose weight, don’t smoke, don’t drink, and exercise more. Taking medication can also treat the condition of dyslipidemia.
