Cholesterol is an indispensable substance in human tissues and cells. It can not only participate in the formation of cell membranes, but also be the raw material of bile acids and vitamin D. The total cholesterol content of children is 120-200mg/dl, and that of adults is 1 10-230mg/dl. No matter whether the total cholesterol is high or low, we should pay attention to it. So what is the reason for the low cholesterol of patients with hepatitis B and small sanyang? The main causes of low cholesterol in hepatitis B are hyperthyroidism, malabsorption syndrome, malnutrition, portal cirrhosis and severe anemia. High cholesterol will increase the risk of coronary heart disease, and the lower LDL, the better. If the low density lipoprotein is too low, it will affect the oxygen carrying capacity of hemoglobin, which will lead to anemia or increase the burden on the heart. Taking certain drugs, such as kanamycin, heparin, vitamin C, aminosalicylic acid, etc., can also lead to low cholesterol. Cholesterol is an important item in liver function examination. When liver disease leads to abnormal metabolism of liver function, it will also lead to low total cholesterol. In addition, malnutrition and emotional instability can also lead to low total cholesterol (will hepatitis B develop into cirrhosis without treatment? In short, when hepatitis B has low cholesterol, it is necessary to do further examination and comprehensive analysis of other liver function tests to find out the reasons for low total cholesterol. If we can't ignore the low total cholesterol caused by liver disease, we must carry out targeted treatment to prevent the consequences of cirrhosis and liver cancer. As a people's own hospital, a hospital trusted by consumers, and a designated medical insurance unit in provinces and cities, it is one of the earliest professional hospitals in China to carry out HBV DNA gene detection technology to treat liver diseases.
