Positive bilirubin means that the patient has elevated bilirubin. There are three main indicators of bilirubin, namely indirect bilirubin, direct bilirubin and total bilirubin. Each indicator can represent different diseases. 1. Elevated indirect bilirubin: It is mainly related to various hemolytic diseases. After the destruction of a large number of red blood cells, a large amount of hemoglobin is converted into indirect bilirubin, which exceeds the processing capacity of the liver and cannot convert all of it into direct bilirubin, causing the indirect bilirubin in the blood to rise. Common disease for hemolytic jaundice, hemolytic jaundice treatment, mainly for the hemolytic disease itself, remove the causative factors, symptomatic treatment, commonly used drugs such as gardenia yellow, adenosine methionine butadisulfate for injection, etc.; 2, direct bilirubin elevation: the elevation of direct bilirubin, indicating that the excretion of bilirubin from the bile duct after processing by liver cells is impaired, suggesting the existence of liver damage, such as viral hepatitis, alcoholic hepatitis, Drug-related hepatitis, etc. The first step is to treat the cause of the disease, followed by liver-protective and anti-yellowness medication. Commonly used drugs are adenosine methionine, ursodeoxycholic acid and Chinese biliary drugs; 3, elevated total bilirubin: the liver plays an important role in the metabolism of bilirubin, including the uptake, binding and excretion of unconjugated bilirubin in the blood by liver cells. It is commonly seen in hepatitis, obstructive jaundice, cirrhosis, neonatal pathological jaundice, cholelithiasis, pancreatic head cancer, hemolytic jaundice and other diseases. Patients are advised to seek prompt medical attention for surgical treatment. It should be noted that bad habits such as smoking and drinking alcohol can lead to bilirubin positivity. Therefore, in daily life, patients should develop good habits, quit smoking and drinking as early as possible, adhere to exercise, adjust their diet and maintain a good mood.
