Lipoprotein a 700mg/L does not heal itself. Lipoprotein a is mainly a cholesterol-rich lipoprotein synthesized under the action of the liver, and the normal value is less than 300mg/L. The value of 700mg/L is out of the normal range. If left unchecked and untreated, it can have an effect on the dissolution of blood clots in the blood vessels, leading to further exacerbation of atherosclerosis and the emergence of cardiovascular and cerebrovascular diseases. Lipoproteins are out of the normal range, indicating that the body is unable to lower the index through self-regulation. Therefore, it is necessary for patients to make adjustments by quitting smoking, quitting alcohol, and eating a low-salt, low-fat diet. At the same time, strengthen physical exercise to promote fat metabolism. If necessary, take niacin drugs under the guidance of the doctor for treatment. If lipoprotein A is found to be elevated, treatment should be carried out under the professional guidance of a doctor to prevent further aggravation of the condition, and it is important not to judge the condition on one’s own based on a single result.
