High lipoprotein a is associated with family genetics, but other causes such as diet and liver disease can also lead to elevated lipoprotein a. 1. Lipoprotein a is a transport protein in the body, and high levels will promote the occurrence and development of atherosclerosis. There are many reasons for elevated lipoprotein a, and heredity is only one of them. 2. Some patients may have abnormal genes, which can lead to abnormal metabolism of lipoproteins, resulting in elevated levels of lipoprotein a in the body and increasing the risk of atherosclerosis. 3. Elevated lipoprotein A is also related to diet, such as eating high-fat foods for a long time. Liver diseases can also lead to elevated levels of lipoprotein a, such as cirrhosis and hepatitis. Patients with elevated lipoprotein should pay attention to find the cause, strictly control the diet, and if necessary, go to the hospital to improve the relevant examination and treatment under the guidance of the doctor.
