Liver damage from mild alcoholic hepatitis can usually be cured by complete abstinence from alcohol and lifestyle changes
Liver damage from mild alcoholic hepatitis can usually be cured by abstaining completely from alcohol and adopting a healthy lifestyle. The liver is a resilient organ and often able to repair much, if not all, of the damage, unless inflicted with continued injury from alcohol.
Liver damage from severe alcoholic hepatitis results in permanent scarring (cirrhosis) and liver cell death (necrosis), but further injury to the liver can be prevented with alcohol abstinence, and symptoms can be managed with good nutrition and medical treatments.
Approximately 25% of heavy drinkers develop alcoholic hepatitis, but it is unclear what factors make some people more prone to alcoholic hepatitis than others. In general, women seem to be less able to tolerate alcohol and hence more at risk than men to experience progression to cirrhosis.
While some patients suffering from alcoholic hepatitis fully recover with abstinence, up to 70% develop liver cirrhosis despite abstinence, possibly because the liver is already significantly compromised at the time of diagnosis.
What is alcoholic hepatitis?
Alcoholic hepatitis is inflammation of the liver resulting from excessive consumption of alcohol. While alcohol is toxic to all cells in the body, it is particularly toxic to the liver since it is primarily metabolized by the liver. The metabolic byproducts of alcohol trigger an inflammatory response resulting in damage and death of liver cells.
The liver is a complex organ that helps digestion with the bile fluid it produces, regulates blood glucose and cholesterol levels, makes enzymes and proteins that the body needs for healthy functioning, fights infections and diseases, and metabolizes and helps remove toxins including alcohol from the body.
Heavy drinking for even a few days can cause the buildup of fat and lead to fatty liver, which is the earliest stage of alcoholic liver disease. Alcoholic hepatitis can also be caused by drinking large quantities of alcohol in a short time period (binge drinking on weekends, for example).
Drinking in excess of 1-2 standard drinks a day regularly is considered heavy drinking and, over a period of time, can result in alcoholic hepatitis as the liver’s ability to process the alcohol is overwhelmed. Unprocessed toxins damage the liver, build up in blood, and affect other organs as well.
Is alcoholic hepatitis the same as cirrhosis?
Alcoholic cirrhosis is an advanced stage of alcoholic liver disease, and is irreversible. Cirrhosis results when sustained inflammation destroys healthy, functioning liver cells which are replaced by scar tissue.
Taking remedial steps for alcoholic hepatitis can help regain significant liver function, but liver damage from cirrhosis is permanent and often leads to liver failure.

What are the symptoms of alcoholic hepatitis?
Mild alcoholic hepatitis may often cause no significant symptoms. The most common symptoms of alcoholic hepatitis include:
- Loss of appetite
- Nausea and vomiting
- Abdominal pain and tenderness
- Abdominal and ankle swelling
- Weight loss
- Weakness and fatigue
- Confusion and lethargy
- Blood in vomit
- Blood in stools
What are the complications of alcoholic hepatitis?
Complications of alcoholic hepatitis include:
- Variceal hemorrhage: Internal bleeding from small veins dilated (varices) due to portal hypertension. Portal vein carries blood from the digestive organs to the liver and the scar tissue caused by alcoholic hepatitis blocks the blood flow and causes portal hypertension.
- Hepatic encephalopathy: Impairment of brain function from toxin buildup in the blood because the damaged liver is unable to process and eliminate the toxins.
- Coagulopathy and thrombocytopenia: Impaired blood clotting function and low platelet count in blood.
- Ascites: Fluid buildup in the abdominal cavity, caused by portal hypertension and the liver’s inability to produce albumin, a protein which prevents fluid from leaking out of blood vessels.
- Spontaneous bacterial peritonitis: Bacterial infection in the membrane (peritoneum) that lines the abdomen, due to ascites and gastrointestinal bleeding.
- Kidney failure: Dysfunction of blood circulation due to portal hypertension damages the kidney leading to water retention.
- Iron overload: Excessive iron getting deposited in the liver causing further damage.
- Infections: Damage to the liver compromises immunity and increases vulnerability to infections.
- Hepatitis C: Common in patients with alcoholic hepatitis, likely because intoxication impairs judgement and leads to risky behavior. Hepatitis C infection hastens the progression to liver cirrhosis and liver failure.
- Liver cancer: Liver damage increases the risk for developing liver cancer.

How is alcoholic hepatitis diagnosed?
A history of heavy alcohol consumption and presence of physical symptoms are usually clear indicators of alcoholic hepatitis. Patients tend to minimize the extent of their alcohol intake; as a result, their doctor may ask for a detailed history and talk to the family, with the patient’s consent.
Tests used to diagnose alcoholic hepatitis include:
- Blood tests such as:
- Imaging tests of the liver such as:
- Endoscopy, in which a thin flexible tube with a lighted camera is passed through the esophagus to look for varices.
- Liver biopsy to determine the extent of damage to the liver, which is usually done only if diagnosis is inconclusive with other tests.
What is the treatment for alcoholic hepatitis?
Treatment for alcoholic hepatitis may include the following:
Ideally, the first and most important step in treating alcoholic hepatitis is immediate and complete alcohol abstinence, or at the very least, reducing intake considerably. To stop drinking, the patient may require:
- Medications to prevent the urge to drink and manage withdrawal symptoms
- Family support
- Joining support groups to reduce risk of relapse
Other lifestyle changes include:
- Giving up smoking (if the patient smokes)
- Taking in adequate nutrition, vitamins, and dietary supplements
- Following a healthy lifestyle and maintaining a healthy weight
Medical treatment will depend on symptoms and complications. Liver inflammation is usually treated with corticosteroids, and antibiotics are prescribed if there is a bacterial infection. Complications from alcoholic hepatitis are likely to require invasive procedures or surgeries.
In cases of extreme liver damage and liver failure, a liver transplant may be an option, but liver is not an easily available organ, nor is every liver failure patient a suitable candidate. The patient’s health condition may not allow the immunity suppression that is required to prevent transplant rejection.
How long can you live with alcoholic hepatitis?
Prognosis for alcoholic hepatitis depends on the extent of liver damage and whether the person abstains from alcohol or continues drinking. The chances of full recovery from mild alcoholic hepatitis are excellent with total and immediate alcohol abstinence. Severe alcoholic hepatitis with complications has significantly high mortality, particularly if a person continues drinking.
In mild and moderate disease with no complications, 30-day mortality may be less than 20%. However, mortality can exceed 40% in the case of severe alcoholic hepatitis with extensive liver damage and complications (decompensated liver disease). Overall, the 1-year mortality rate after hospitalization for alcoholic hepatitis is approximately 40%.
