What are the precautions before checking liver function?

Generally, before a liver function test, it is important to adjust your diet, avoid alcohol consumption, ensure adequate rest, avoid strenuous exercise, and maintain emotional stability. Detailed explanations are as follows:

1. Dietary Adjustment

On the day before the test, avoid consuming excessively greasy or high-protein foods, as well as foods containing additives such as pigments and preservatives. These foods may increase the burden on the liver and affect the accuracy of the test results. Additionally, maintain a light diet to ensure the liver remains in a relatively normal metabolic state before the test.

2. Avoid Alcohol Consumption

Avoid drinking alcohol for at least one week before the test to prevent damage to liver cells that could lead to abnormal test results.

3. Ensure Adequate Rest

Ensure sufficient sleep before the test and avoid excessive fatigue. Fatigue may lead to decreased liver function and affect the accuracy of the test results. Proper rest helps the liver recover and repair itself, ensuring accurate test results.

4. Avoid Strenuous Exercise

Avoid strenuous exercise before the test because intense physical activity can increase the metabolic burden on the liver, potentially causing abnormal elevations in indicators such as transaminases.

5. Maintain Emotional Stability

Emotional stability is very important for liver health. Maintain a relaxed and cheerful mood before the test, and avoid excessive tension and anxiety.

Regular moderate exercise, such as walking or jogging, should be practiced to help promote blood circulation and metabolism, thereby reducing the burden on the liver.
