What causes liver jaundice?
Liver jaundice, which is the phenomenon of yellow staining in the skin, sclera and other parts, is usually related to abnormal bilirubin metabolism. Bilirubin is a product of the breakdown of hemoglobin and is normally processed and excreted by the liver. When this process is blocked, bilirubin accumulates in the body, causing jaundice. The following are common causes of liver jaundice and related data analysis.
1. Common causes of liver jaundice
| Cause classification | specific disease or factor | Proportion (reference data) |
|---|---|---|
| Liver disease | Hepatitis, cirrhosis, liver cancer | 45% |
| bile duct obstruction | Gallstones, bile duct tumors, cholangitis | 30% |
| hemolytic disease | Hereditary hemolytic anemia, transfusion reaction | 15% |
| Others | Drug-induced liver injury, neonatal jaundice | 10% |
2. Pathological mechanism of liver jaundice
The occurrence of liver jaundice is related to multiple aspects of bilirubin metabolism:
1.Too much bilirubin production: Hemolytic disease causes massive destruction of red blood cells and bilirubin production exceeds the liver's processing capacity.
2.liver cell damage: Hepatitis, cirrhosis and other diseases cause liver cell function to be damaged and unable to absorb and combine bilirubin normally.
3.bile duct obstruction: Gallstones or tumors block the bile ducts, preventing conjugated bilirubin from being excreted into the intestines.
3. Clinical manifestations of liver jaundice
| Symptoms | frequency of occurrence | Related diseases |
|---|---|---|
| Yellow staining of skin and sclera | 100% | All patients with liver jaundice |
| Darker urine color | 80% | Biliary tract obstruction, hepatitis |
| Fatigue, loss of appetite | 70% | Hepatitis, cirrhosis |
| abdominal pain | 50% | Gallstones, cholangitis |
4. Diagnosis and treatment of liver jaundice
The diagnosis of liver jaundice requires a combination of medical history, physical examination and laboratory tests:
1.laboratory tests: Including serum bilirubin (direct, indirect), liver function, blood routine, etc.
2.Imaging examination: Ultrasound, CT or MRI can help detect biliary obstruction or liver lesions.
3.Treatment principles: Treatment for the cause, such as antiviral treatment for hepatitis, surgery to relieve biliary obstruction, etc.
5. Prevention of liver jaundice
To prevent liver jaundice, you need to start from the following aspects:
1.Get vaccinated: For example, hepatitis B vaccine can prevent viral hepatitis.
2.healthy eating: Avoid high-fat diet to reduce the risk of gallstones.
3.Avoid hepatotoxic drugs: Liver function needs to be monitored if you take certain Chinese or Western medicines for a long time.
Yellow liver is a common manifestation of many diseases, and it is crucial to detect and clarify the cause in time. If symptoms such as yellowish skin appear, it is recommended to seek medical advice as soon as possible.
