Alcoholic hepatitis is a serious inflammatory condition of the liver caused by heavy alcohol use over an extended period. It develops when prolonged drinking triggers a cascade of damage and inflammation in liver cells, and in its severe form, it can be fatal within weeks. The condition ranges from mild, where symptoms may be subtle, to severe, where one-month mortality rates reach 30% to 50% without treatment.
How Alcohol Damages the Liver
When you drink heavily for years, your liver cells bear the brunt of processing all that alcohol. The breakdown of alcohol generates harmful byproducts that stress liver cells in multiple ways: they overwhelm the cell’s internal cleanup systems, produce damaging molecules called reactive oxygen species, and eventually kill liver cells outright. As cells die, they release distress signals that recruit immune cells, particularly a type of white blood cell called neutrophils, which flood into the liver tissue.
Here’s where things spiral. Those immune cells release their own toxic substances and inflammatory signals, including proteins like TNF-alpha and interleukin-1 beta, which ramp up inflammation further. The damaged liver cells themselves release chemical signals that pull in even more neutrophils. Neutrophils in the livers of people with alcoholic hepatitis are actually the major source of one of these recruitment signals, creating a self-sustaining loop of inflammation. Meanwhile, other immune cells called macrophages release growth factors that activate the liver’s scar-producing cells, setting the stage for fibrosis.
This combination of direct alcohol toxicity, oxidative damage, immune cell infiltration, and inflammatory signaling is what makes alcoholic hepatitis distinct from simple fatty liver. It’s an active, aggressive inflammatory process rather than just passive damage from alcohol.
Who Is at Risk
Most people who develop alcoholic hepatitis drink more than 100 grams of alcohol per day, which works out to roughly six or seven standard drinks. Many drink 150 to 200 grams daily. However, clinicians consider anyone consuming more than 30 to 50 grams per day (about two to four drinks) for more than five to ten years to be at risk for alcohol-related liver disease. The relationship between how much you drink and your risk is dose-dependent: more alcohol over more years means higher risk.
That said, not everyone who drinks heavily develops alcoholic hepatitis. Genetics, nutritional status, and other individual factors play a role in who crosses the threshold from fatty liver into active inflammation.
Signs and Symptoms
Jaundice, the yellowing of your skin and eyes, is the hallmark of alcoholic hepatitis. While visible jaundice shows up in 40% to 60% of hospitalized cases, elevated bilirubin levels (the pigment that causes yellowing) are present in nearly every patient. Other common symptoms include pain in the upper right side of the abdomen, fever, rapid heart rate, and a tender, enlarged liver.
Among hospitalized patients, the numbers paint a clear picture of how the disease presents:
- Enlarged liver: 81% to 87% of patients
- Jaundice: 37% to 60%
- Fluid buildup in the abdomen (ascites): 35% to 57%
- Confusion or altered consciousness: 18% to 45%
In severe cases, complications escalate quickly. The liver can fail to the point where it no longer filters toxins from the blood, leading to confusion and disorientation. Kidney function can deteriorate. Blood clotting becomes impaired, raising the risk of dangerous bleeding.
How It’s Diagnosed
Doctors look for a characteristic pattern in blood tests. One reliable clue is the ratio of two liver enzymes, AST and ALT. In most other types of liver disease, these enzymes rise roughly in proportion. In alcoholic hepatitis, AST runs about twice as high as ALT. A ratio of 2:1 or greater is highly suggestive of alcohol-related liver injury.
To gauge severity, doctors calculate a score called the Maddrey Discriminant Function using clotting time and bilirubin levels. A score of 32 or higher defines severe alcoholic hepatitis. Patients who score below 32 have about a 90% survival rate at 30 days even without specific treatment. Those at 32 or above face mortality exceeding 20% to 30% at 30 days, and this threshold guides decisions about whether to start more aggressive treatment.
Treatment for Severe Cases
For severe alcoholic hepatitis (a Maddrey score of 32 or higher), most experts recommend a course of corticosteroids, specifically prednisolone at 40 milligrams per day for 28 to 30 days. This aims to suppress the intense inflammatory response that’s destroying liver tissue. The treatment is a single course and is not repeated unless someone resumes drinking and develops another episode.
After one week of corticosteroid treatment, doctors reassess using another scoring tool called the Lille Model. This score combines six factors, including age, kidney function, and how much bilirubin levels have changed since treatment began. A Lille score of 0.45 or higher at day seven signals that steroids aren’t working. About 40% of patients fall into this non-responder category. For these patients, continuing corticosteroids offers no survival benefit and may actually increase the risk of infection, so treatment is stopped.
The difference in outcomes between responders and non-responders is stark. Patients with a Lille score below 0.45 have an 85% six-month survival rate. Those above 0.45 have only a 25% six-month survival rate.
Nutrition as Part of Recovery
Malnutrition is extremely common in people with alcoholic hepatitis, and it worsens outcomes. European clinical nutrition guidelines recommend that patients aim for 35 to 40 calories per kilogram of body weight per day, along with 1.2 to 1.5 grams of protein per kilogram. For a 70-kilogram (154-pound) person, that means roughly 2,450 to 2,800 calories and 84 to 105 grams of protein daily. At minimum, patients should consume at least 21.5 calories per kilogram per day. Oral feeding is strongly preferred, and getting adequate nutrition is considered a core part of treatment rather than an afterthought.
Liver Transplantation
Traditionally, liver transplant programs required patients to demonstrate six months of sobriety before being considered for a transplant. This effectively excluded people with severe alcoholic hepatitis who were dying of their current episode. Over the past decade, that has changed significantly.
Early liver transplantation is now offered at select centers for patients with severe alcoholic hepatitis who don’t respond to medical therapy (a Lille score above 0.45 or a continuously rising severity score). Candidates must meet strict criteria: it must be their first episode of liver failure, they need strong family support, no severe additional health conditions, and a commitment to lifelong abstinence from alcohol. A broad team of medical professionals must reach consensus before proceeding.
The survival data for early transplantation is striking. In the landmark French study, 77% of transplanted patients were alive at six months compared to 23% of those who didn’t receive a transplant. A study from Mount Sinai found six-month survival of 89% with transplant versus 11% without. Data from 12 U.S. centers covering 147 highly selected patients showed survival rates of 94% at one year and 84% at three years after transplantation. These outcomes are comparable to transplant results for patients with alcoholic cirrhosis who met the traditional six-month sobriety requirement.
The Central Role of Abstinence
Stopping alcohol completely is the single most important factor in surviving alcoholic hepatitis and preventing progression to cirrhosis. No medication can compensate for continued drinking. In mild to moderate cases, abstinence alone can allow the liver to heal substantially over weeks to months. In severe cases, abstinence is necessary for any other treatment to have a chance of working. Every treatment decision, from corticosteroids to transplant eligibility, is built on the assumption that the patient will stop drinking permanently.
