Understanding Your LFT Results: What to Do After Alarming Liver Function Tests

Today, I received the results of my liver function tests (LFT), and the results showed some concerning values. Specifically, my ALT level is 75 U/L (normal range 0-34), AST is 33 U/L (normal range 0-31), and Gamma GT is 46 U/L (normal range 9-36). Bilirubin levels were within the normal range for both total and direct bilirubin. But do these numbers indicate a serious health issue, or can they be improved by simply reducing alcohol consumption?

Interpreting LFT Results

The liver is a vital organ responsible for numerous functions, including detoxification, protein synthesis, and metabolism of fats, carbohydrates, and drugs. If liver function tests show abnormal results, it generally indicates some level of liver damage or dysfunction. However, the degree of liver damage often depends on the specific enzyme levels and other clinical context.

ALT (Alanine Aminotransferase)

ALT, commonly known as SGPT (Serum Glutamic Pyruvic Transaminase), is found in high amounts in the liver. Elevated ALT levels, as seen with a result of 75 U/L, typically indicate liver inflammation or damage.

AST (Aspartate Aminotransferase)

AST, also known as SGOT (Serum Glutamic Oxaloacetic Transaminase), is present in both the liver and other organs, such as the heart, muscle, and kidneys. An AST level of 33 U/L is within the normal range, but if it were higher, it could also suggest liver damage. However, because AST is present in multiple organs, it is less specific to liver function compared to ALT.

Gamma GT (Gamma-Glutamyl Transferase)

Gamma GT is predominantly found in the liver, but it is also present in other organs. It is most associated with alcohol consumption and liver diseases. A Gamma GT level of 46 U/L is a bit elevated, but not alarming. It is often used to assess the likelihood of liver damage associated with alcohol.

Bilirubin

Total and direct bilirubin levels in this case are within the normal range, which is a good sign. Bilirubin is a product of red blood cell breakdown and its levels are closely monitored in liver function tests. Normal bilirubin levels can rule out some types of liver issues but do not entirely rule out others.

Is This a Cause for Concern?

Many factors can influence liver function tests, including lifestyle, diet, and even medications. For someone who consumes alcohol, the elevated levels of ALT and Gamma GT are consistent with alcohol-related liver changes. However, it is important to note that none of the values are so high that they wouldn’t be expected to return to normal if alcohol consumption were decreased or eliminated.

Alcohol Consumption and Liver Health

Alcohol is a major risk factor for liver damage. For individuals like you, who are 26 and consume alcohol, reducing or quitting alcohol use is often recommended. This can help to improve liver function and potentially reverse some of the damage caused by alcohol. However, it is crucial to consult with a healthcare provider to get a comprehensive evaluation of your liver health.

Should You See a Doctor?

Given the results of your LFTs, it is recommended that you make an appointment to see a healthcare provider. While elevation in liver enzymes can be caused by simple things like overuse of alcohol or even stress, sometimes it can be a sign of more serious liver conditions. Your healthcare provider will be able to perform further tests and provide a more detailed evaluation, including but not limited to:

Further blood tests to check for hepatitis or other infections. Imaging tests like an ultrasound or MRI to look for structural abnormalities in the liver. Complete medical history to understand any other exposures or health issues that may affect liver function.

Takeaways

It's important to take these results seriously and act accordingly. Reducing alcohol consumption, maintaining a healthy diet, and seeking medical advice can significantly improve liver function. Remember, your liver is a resilient organ, and with the right steps, you can improve your health and liver function.

If you are concerned about your liver function tests, here are some tips to help you get started:

Stop or reduce alcohol consumption. Adopt a healthy diet full of fruits, vegetables, and lean proteins. Stay hydrated by drinking plenty of water. Exercise regularly for overall health. Schedule an appointment with a healthcare provider to discuss further steps.

Understanding and addressing these issues can make a significant difference in your long-term health. Take care of your liver, and it will return the favor.
