Alcoholic Liver Disease
What is Alcoholic Liver Disease?
Alcoholic liver disease is a condition where your liver becomes damaged from drinking too much alcohol over time. Your liver is responsible for filtering toxins from your blood, producing important proteins, and helping digest food. When alcohol overloads your liver, it can cause inflammation, scarring, and eventually permanent damage.
The disease progresses through several stages. Fatty liver is the earliest stage, where fat builds up in liver cells. Alcoholic hepatitis comes next, causing inflammation and cell death. Cirrhosis is the most advanced stage, where scar tissue replaces healthy liver tissue. Early stages can often be reversed if you stop drinking alcohol. Advanced stages may cause permanent damage.
Alcoholic liver disease affects about 10 to 20 percent of people who drink heavily over many years. Your liver has a remarkable ability to heal itself if you catch problems early. Understanding your risk and getting tested can help you protect your liver before serious damage occurs.
Symptoms
- Fatigue and weakness that gets worse over time
- Loss of appetite and unintended weight loss
- Nausea and vomiting, especially in the morning
- Yellowing of the skin and eyes, called jaundice
- Abdominal pain or tenderness in the upper right side
- Swelling in the legs, ankles, or abdomen
- Confusion or difficulty concentrating
- Dark urine or pale stools
- Easy bruising or bleeding
- Spider-like blood vessels on the skin
Many people with early-stage alcoholic liver disease have no symptoms at all. Your liver can be damaged significantly before you notice any problems. This makes regular blood testing important for anyone who drinks alcohol regularly.

Causes and risk factors
Alcoholic liver disease is caused by drinking too much alcohol over an extended period. When you drink, your liver breaks down alcohol to remove it from your blood. This process creates harmful substances that damage liver cells and cause inflammation. Heavy drinking over 10 to 20 years significantly increases your risk. Women develop liver damage with less alcohol than men due to differences in how the body processes alcohol.
Several factors increase your risk beyond just alcohol consumption. Drinking on an empty stomach concentrates alcohol damage. Genetics play a role, as some people have gene variants that affect alcohol metabolism. Having hepatitis C or other liver conditions accelerates damage. Poor nutrition and obesity make liver disease worse. Binge drinking, even occasionally, causes more damage than steady moderate drinking.
How it's diagnosed
Alcoholic liver disease is diagnosed through blood tests, medical history, and physical examination. Your doctor will ask about your drinking habits and check for physical signs like an enlarged liver or jaundice. Blood tests are the primary tool for detecting liver damage before symptoms appear. These tests measure liver enzymes and other markers that reveal how well your liver is functioning.
Rite Aid's preventive health panel includes key tests that detect alcoholic liver disease. The panel measures AST, GGT, MCV, fibrinogen, and urine urobilinogen. AST is typically elevated more than ALT in alcoholic liver disease, with a ratio greater than 2. GGT is often the earliest marker to rise with regular alcohol use. Your doctor may order additional imaging tests like ultrasound or FibroScan to assess liver scarring.
Treatment options
- Stop drinking alcohol completely, which is the most important step
- Join support groups like Alcoholics Anonymous or SMART Recovery
- Work with a therapist or addiction specialist for behavioral support
- Eat a nutrient-rich diet with adequate protein and calories
- Take vitamin supplements, especially B vitamins and vitamin K
- Avoid medications that stress the liver, including acetaminophen
- Get vaccinated for hepatitis A and B to prevent additional liver damage
- Medications like naltrexone or acamprosate may help reduce alcohol cravings
- Corticosteroids may be prescribed for severe alcoholic hepatitis
- Liver transplant may be considered for advanced cirrhosis in select cases

Frequently asked questions
Early stages like fatty liver can often be reversed completely if you stop drinking alcohol. Your liver can regenerate healthy tissue and recover normal function within weeks to months. Advanced stages like cirrhosis involve permanent scarring that cannot be fully reversed. However, stopping alcohol can prevent further damage and allow your remaining liver tissue to function better.
Drinking more than 2 drinks per day for men or 1 drink per day for women over many years increases your risk significantly. Heavy drinking is defined as 15 or more drinks per week for men or 8 or more for women. However, individual tolerance varies based on genetics, body weight, and other health factors. Some people develop liver damage with less alcohol consumption.
AST is an enzyme found in liver cells that leaks into your blood when those cells are damaged. In alcoholic liver disease, AST is typically higher than another liver enzyme called ALT. A ratio of AST to ALT greater than 2 suggests alcohol-related damage. Chronic alcohol damages the mitochondria in liver cells, causing AST to rise preferentially.
GGT is an enzyme that rises early when your liver is stressed by alcohol. It can be elevated before you develop symptoms or other abnormal test results. GGT levels stay high as long as you continue drinking and usually drop within weeks of stopping. This makes it useful for both detecting alcohol-related liver damage and monitoring recovery.
Fatty liver can improve within 2 to 4 weeks of stopping alcohol. Inflammation from alcoholic hepatitis may take several months to resolve. Blood test results often start improving within days to weeks. However, cirrhosis involves permanent scarring that remains even after you stop drinking, though liver function can still improve.
Fatty liver is the earliest and mildest stage where fat accumulates in liver cells but causes minimal damage. It is usually reversible with lifestyle changes. Cirrhosis is the most advanced stage where scar tissue has replaced healthy liver tissue throughout the organ. Cirrhosis is largely irreversible and can lead to liver failure.
No amount of alcohol is safe if you have alcoholic liver disease at any stage. Even small amounts can prevent healing and cause ongoing damage. Your liver needs complete abstinence from alcohol to recover. If you want to protect your liver health, stopping all alcohol consumption is essential.
MCV measures the average size of your red blood cells. Chronic alcohol consumption can increase MCV, making your red blood cells larger than normal. This happens because alcohol interferes with folate metabolism and affects bone marrow function. Elevated MCV combined with high liver enzymes suggests alcohol-related problems.
Most cases can be diagnosed through blood tests, imaging, and medical history without a biopsy. A biopsy involves taking a small tissue sample from your liver with a needle. It may be needed if your diagnosis is unclear or if doctors suspect other liver conditions. Non-invasive tests like FibroScan can often assess scarring without biopsy.
Untreated alcoholic liver disease progresses from fatty liver to hepatitis to cirrhosis over years. Cirrhosis can lead to liver failure, where your liver can no longer perform vital functions. Complications include internal bleeding, fluid buildup, kidney failure, and liver cancer. Advanced liver disease is life-threatening and may require a liver transplant.
