The causes of high apolipoprotein a mainly include chronic hepatitis, taking antiepileptic or contraceptive drugs, pregnancy and alcohol consumption. 1. Chronic hepatitis: most of the body’s apolipoprotein a is secreted in the liver, and when the liver has inflammatory lesions or dysfunction, and is not treated or treated inappropriately, abnormal elevation of apolipoprotein a will occur. 2. Taking antiepileptic or contraceptive drugs: these two kinds of drugs will lead to different degrees of ApoA elevation in the body, and the ApoA content will gradually decrease to the normal level after stopping the drugs. 3. Alcohol consumption: long-term alcohol consumption can easily lead to alcoholic hepatitis or cirrhosis, which will cause great damage to the liver and also lead to high ApoA. 4. Pregnancy: The immature development of fetal organs requires more apolipoproteins to remove the lipids produced by the fetus, so the liver synthesized apolipoprotein a will be high in pregnant women. It is recommended that patients with the above conditions should go to regular hospitals for timely consultation and standardized treatment under the guidance of doctors, so as to avoid delaying the condition.
