How to check for liver abnormalities
In recent years, with the acceleration of life pace and changes in diet structure, abnormal liver function has become a health issue that more and more people pay attention to. Hepatic abnormalities may be caused by a variety of reasons, including viral hepatitis, fatty liver, alcoholic liver, drug-induced liver damage, etc. Timely checking liver function is crucial for early detection and treatment of liver diseases. This article will introduce in detail the examination methods for liver function abnormalities, and combine the popular topics and hot contents of the entire network for the past 10 days to help readers fully understand the relevant examination items.
1. Common symptoms of liver function abnormality
Before discussing the examination method, you need to understand the possible symptoms of liver dysfunction. Here are some common manifestations:
| symptom | Possible Causes |
|---|---|
| Fatigue, loss of appetite | Decreased liver metabolic function |
| Yellowing of the skin and whites of the eyes (jaundice) | Bilirubin metabolism abnormalities |
| Abdominal discomfort or pain | Enlargement or inflammation of the liver |
| The color of urine becomes darker | Abnormal bilirubin excretion |
| Prone to bleeding or bruising | Clotting abnormalities |
2. Main items of liver function examination
When the above symptoms occur, doctors usually recommend liver function tests. The following are common liver function test items:
| Check items | Normal reference value | Clinical significance |
|---|---|---|
| Alkaline transaminase (ALT) | 7-40 U/L | Reflects the degree of liver cell damage |
| AST | 13-35 U/L | Reflects hepatocyte damage and heart disease |
| Alkaline phosphatase (ALP) | 40-150 U/L | Reflect bile tract obstruction or bone disease |
| Total bilirubin (TBIL) | 3.4-20.5 μmol/L | Reflect bilirubin metabolism |
| Albumin (ALB) | 35-55 g/L | Reflects liver synthesis function |
| Prothrombin time (PT) | 11-14 seconds | Reflects liver coagulation function |
3. Precautions for liver function examination
In order to ensure the accuracy of the examination results, the following things should be paid attention to before performing liver function examination:
1.Fasting examination:Most liver function tests require an empty stomach of 8-12 hours, and blood tests are usually recommended in the morning when the fasting state is usually taken.
2.Avoid strenuous exercise:Severe exercise should be avoided within 24 hours before the examination to avoid affecting indicators such as aminotransferase.
3.Avoid drinking:Alcohol should be avoided 3 days before the examination, as alcohol will directly affect liver function indicators.
4.Inform the medication status:Some drugs can affect the results of liver function tests. Doctors should be informed before the examination.
4. Further examination of liver function abnormalities
If a routine liver function test is found to be abnormal, your doctor may recommend the following further tests:
| Check type | Purpose of inspection |
|---|---|
| Markers of viral hepatitis | Detect virus infections such as hepatitis B and hepatitis C |
| Abdomen ultrasound | Observe liver morphology, size and structure |
| CT or MRI | Evaluation of liver lesions in more detail |
| Liver fibrosis scan (FibroScan) | Assess the degree of liver fibrosis |
| Liver biopsy | Confirmed liver lesions |
5. Recent hot topics: The relationship between liver function abnormality and lifestyle
According to the analysis of hot content on the entire network for the past 10 days, the relationship between liver function abnormalities and lifestyle has become a hot topic of discussion. Here are some key points to note:
1.Non-alcoholic fatty liver:As the obese population increases, the incidence of non-alcoholic fatty liver is increasing year by year, becoming a common cause of liver dysfunction.
2.Staying up late and liver function:Research has found that staying up late for a long time will affect the liver's detoxification and metabolic function and increase the risk of liver abnormalities.
3.Diet and liver health:A high-fat and sugar diet will not only lead to obesity, but also increase the burden on the liver, while a diet rich in antioxidants can help protect the liver.
4.Exercise and liver function:Moderate exercise can improve liver fat metabolism, prevent and improve fatty liver, but excessive exercise may lead to temporary increase in aminotransferase.
6. How to prevent liver function abnormalities
Based on recent hot topics and medical advice, the following measures can help prevent liver dysfunction:
1.Regular physical examinations:It is recommended that people over 40 years old undergo liver function examinations once a year, and high-risk groups (such as hepatitis B carriers and long-term drinkers) should shorten the examination interval.
2.Healthy diet:Reduce intake of high-fat and high-sugar foods and increase intake of vegetables, fruits and high-quality protein.
3.Moderate exercise:Perform moderate intensity exercises 3-5 times a week for about 30 minutes each time.
4.Weight control:Maintain BMI within the normal range of 18.5-23.9 to reduce visceral fat accumulation.
5.Avoid substance abuse:Do not take medications on your own for a long time, especially those that may damage the liver.
6.Vaccination:Get hepatitis B vaccine in time to prevent viral hepatitis.
Conclusion
Early detection and treatment of liver dysfunction is essential for maintaining overall health. By regularly checking liver function indicators and combining a healthy lifestyle, liver function abnormalities can be effectively prevented and improved. If liver function abnormalities are found in the examination, seek medical treatment in time, clarify the cause and receive professional treatment. Remember, the liver is a silent organ. When the symptoms are obvious, serious damage is often seen, so regular examinations are especially necessary.
