Tests
Non-alcoholic fatty liver disease (NAFLD) and alcoholic fatty liver disease (AFLD) are two of the most common liver issues globally, often leading to more serious conditions such as fibrosis, cirrhosis, or even liver cancer if left untreated. What makes this alarming is that fatty liver disease is mostly silent in its early stages, showing few or no symptoms. Detecting it early is crucial, and this is where Liver Function Tests (LFTs) play a key role.
LFTs are diagnostic tests that evaluate markers in your blood to determine how well your liver is functioning. This makes them one of the most accessible and effective tools for diagnosing liver damage at an early stage, particularly in the case of fatty liver disease.
What is Fatty Liver Disease?
Fatty liver disease occurs when excess fat builds up in liver cells, impairing its ability to function effectively. There are two main types of fatty liver disease:
Non-Alcoholic Fatty Liver Disease (NAFLD): Not associated with heavy alcohol use, NAFLD is linked to metabolic conditions such as obesity, type 2 diabetes, or high cholesterol.
Alcoholic Fatty Liver Disease (AFLD): Caused by excessive alcohol consumption, AFLD damages the liver as it struggles to process alcohol.
While the mild fat buildup in the liver may not cause immediate health problems, prolonged or untreated conditions can lead to advanced liver damage.
Symptoms of Fatty Liver Disease
Fatty liver disease is often asymptomatic in its early stages. However, as the condition progresses, individuals may experience:
Because symptoms appear late, early detection through tests is critical for timely intervention.
What Are Liver Function Tests (LFTs)?
Liver function tests (LFTs) are blood tests that measure enzymes, proteins, and substances produced or processed by the liver. These markers help evaluate the health and performance of your liver. Some of the most important components evaluated in LFTs include:
Each result provides insight into how various aspects of the liver are functioning, detecting abnormalities that might signal early damage or disease.
How LFTs Detect Early Signal of Fatty Liver Disease
LFTs are particularly useful for diagnosing liver damage in the early stages of fatty liver disease. Here's how these tests contribute to early diagnosis:
Importance of Early Detection
The earlier liver damage is identified, the better the prognosis. Early intervention can halt disease progression, improve liver function, and reduce the risk of complications. Fatty liver disease, especially NAFLD, is reversible in its early stages with lifestyle changes.
Benefits of Early LFT Screening
What to Expect During an LFT
If you’re undergoing a liver function test, here’s what happens:
Next Steps After LFT Results
Whether your results are normal, borderline, or abnormal, follow-up actions are essential for proper management.
If Results Are Normal
Continue maintaining a healthy lifestyle with balanced nutrition, regular exercise, and avoiding alcohol. Regular check-ups can ensure your liver persists in good health.
If Results Indicate Abnormalities
Your doctor may recommend additional diagnostic tests such as a FibroScan, advanced imaging, or a biopsy to determine the extent of liver damage. Lifestyle changes, dietary modifications, and in some cases, medications will be prescribed to manage the condition.
Lifestyle Changes for Fatty Liver Disease
Addressing fatty liver disease goes beyond testing. Proactive adjustments to daily habits can improve liver health dramatically:
