Elevated Liver Enzymes: Causes and Health Tips for Young Adults - Gastroenterology and Hepatology

More Info

---

Elevated liver enzymes, specifically alanine aminotransferase (ALT) and aspartate aminotransferase (AST), can be concerning, especially for young adults like your classmate who is only 19 years old. The normal range for ALT is typically below 40 U/L, and for AST, it is generally below 35 U/L. Your classmate's levels of ALT (GPT) at 105 U/L and AST (GOT) at 61 U/L are indeed elevated and warrant further investigation.


Possible Causes of Elevated Liver Enzymes
1. Non-Alcoholic Fatty Liver Disease (NAFLD): This is one of the most common causes of elevated liver enzymes in young adults, particularly if there is a history of obesity, poor diet, or sedentary lifestyle. NAFLD can progress to non-alcoholic steatohepatitis (NASH), which can lead to liver damage.

2. Viral Hepatitis: Although your classmate has tested negative for hepatitis B, other viral infections such as hepatitis A or C could still be a factor. It’s essential to ensure comprehensive testing for all types of viral hepatitis.

3. Medications and Supplements: Certain medications, including over-the-counter pain relievers like acetaminophen, and some herbal supplements can cause liver enzyme elevations. Your classmate should review any medications or supplements he is taking with a healthcare provider.

4. Alcohol Consumption: Even if your classmate does not drink heavily, moderate alcohol consumption can affect liver enzymes. It’s important to consider all sources of alcohol intake.

5. Autoimmune Liver Disease: Conditions like autoimmune hepatitis can cause elevated liver enzymes, although they are less common in young adults.

6. Metabolic Disorders: Conditions such as Wilson's disease or hemochromatosis can lead to liver damage and elevated enzymes, though these are rarer.

7. Exercise-Induced Elevation: Intense physical activity can sometimes cause temporary elevations in liver enzymes, particularly if the exercise is strenuous.


Health Tips for Young Adults
1. Dietary Modifications: Encourage your classmate to adopt a balanced diet rich in fruits, vegetables, whole grains, and lean proteins. Reducing the intake of saturated fats, sugars, and processed foods can help improve liver health.

2. Regular Exercise: Engaging in regular physical activity can help maintain a healthy weight and reduce the risk of fatty liver disease. Aim for at least 150 minutes of moderate aerobic activity each week.

3. Avoid Alcohol: If your classmate consumes alcohol, it may be beneficial to reduce or eliminate intake, especially until liver function is assessed and improved.

4. Stay Hydrated: Drinking plenty of water can support overall health and help the liver function optimally.

5. Regular Check-ups: It’s crucial for your classmate to follow up with a healthcare provider for further evaluation of the elevated liver enzymes. This may include additional blood tests, imaging studies like an ultrasound, or even a liver biopsy if necessary.

6. Manage Stress: Chronic stress can impact overall health, including liver function. Encourage stress management techniques such as mindfulness, yoga, or other relaxation methods.

7. Avoid Self-Medication: Your classmate should avoid taking any medications or supplements without consulting a healthcare provider, as some can exacerbate liver issues.


Conclusion
Elevated liver enzymes in a young adult can be a sign of various underlying health issues, and it is essential to identify the cause through proper medical evaluation. By adopting a healthy lifestyle and following up with healthcare professionals, your classmate can take proactive steps to improve liver health and overall well-being. Regular monitoring and lifestyle modifications can significantly impact liver function and prevent potential complications in the future.
