Alcohol-related liver disease is a spectrum of liver conditions caused by chronic heavy alcohol consumption, ranging from fatty liver to cirrhosis. It is caused by the toxic effects of ethanol and its metabolite acetaldehyde, which trigger inflammation, oxidative stress, and progressive scarring of liver tissue. The Alanine Aminotransferase (ALT) test is the most important test for detecting alcohol-related liver damage because it measures enzyme levels released when liver cells are injured.

Alcohol-related liver disease is caused by the toxic effects of ethanol and its metabolite acetaldehyde on liver cells. When you drink heavily over time, these substances trigger inflammation, oxidative stress, and fat accumulation in the liver. The damage progresses through stages: fatty liver disease develops first, followed by alcoholic hepatitis with more severe inflammation, and eventually cirrhosis where permanent scarring replaces healthy liver tissue. The amount and duration of alcohol consumption directly correlate with the severity of liver damage.
The Alanine Aminotransferase (ALT) test is the most important test for alcohol-related liver disease because it detects liver cell damage by measuring ALT enzyme levels in your blood. When chronic alcohol consumption inflames and damages liver cells, they release ALT into your bloodstream, causing elevated levels. This test is essential for early detection because liver damage often occurs without obvious symptoms. Healthcare providers use ALT levels along with the pattern of elevation over time to assess the severity of liver injury and monitor whether the disease is progressing or improving with treatment and alcohol cessation.
You should get tested if you have a history of heavy drinking for several years, even if you feel fine. Early detection is crucial because alcohol-related liver disease often develops without noticeable symptoms until significant damage has occurred. Get tested if you notice fatigue, unexplained weight loss, abdominal pain or swelling, yellowing of skin or eyes, or easy bruising. Regular monitoring is especially important if you are trying to reduce alcohol consumption or if previous tests showed borderline elevated liver enzymes, as tracking changes helps assess whether liver damage is improving or worsening.

What this means
Your ALT level is slightly elevated above the optimal range, which may indicate mild liver stress or inflammation. While this is not necessarily alarming, it could be related to fatty liver, certain medications, recent alcohol use, or other factors affecting liver health and may benefit from lifestyle changes and monitoring.
Recommended actions
Limit or avoid alcohol consumption completely for several weeks
Focus on a balanced diet rich in vegetables, lean proteins, and whole grains while reducing processed foods and added sugars
Maintain a healthy weight through regular exercise like walking, swimming, or cycling
Retest in 4-6 weeks to monitor if levels improve with lifestyle changes
Not overhyped or overpriced. Just comprehensive blood testing made simple and for everyone.
