Thickening of blood lipids is clinically known as hyperlipidemia. The causes of hyperlipidemia are divided into primary and secondary, which are generally treated by general therapy, medication and surgery. 1. Primary: The cause of primary hyperlipidemia is unknown, and it is suspected to be a combination of several gene mutations or environmental factors leading to dyslipidemia. Clinically, hyperlipidemia is often associated with poor dietary habits, lack of activity, obesity, smoking, alcoholism, and so on. Diet should be controlled, exercise should be increased, smoking and alcohol should be stopped, and medication can be given if necessary. 2. Secondary: Diseases or medications can cause secondary hyperlipidemia. For example, diabetes mellitus, nephrotic syndrome, liver disease, hypothyroidism, systemic lupus erythematosus, polycystic ovary syndrome, and Cushing’s syndrome. Long-term application of certain drugs can also lead to blood thickening, including glucocorticoids, thiazide diuretics, beta-blockers and so on. The treatment is generally taken to treat the cause. If you feel unwell, you should go to the hospital in time to avoid delaying your condition.
