Years of alcohol abuse can cause the liver to become inflamed and swollen. Having hepatitis C or other liver diseases with heavy alcohol use can rapidly increase the development of cirrhosis. However, in advanced alcoholic liver disease, liver regeneration is impaired, resulting in permanent damage to the liver. The liver is responsible for metabolizing or processing ethanol, the main component of alcohol. Over time, the liver of a person who drinks heavily can become damaged and cause alcoholic liver disease. It is important to encourage patients with alcoholic liver disease to participate in counseling programs and psychological assistance groups.

These receptors activate KCs to produce proinflammatory cytokines and promote free-radical formation via induction of the reduced nicotinamide adenine dinucleotide phosphate (NADPH) oxidase and CYP2E1. The resulting reactive oxygen and nitrogen species promote the release of proinflammatory cytokines, which in turn increase inflammasome activation in KCs and the release of chemokines that attract circulating immune cells to the liver. Inflammasomes are innate immune-system sensors that regulate the activation of caspase-1 and induce inflammation in response to microbial/ viral pathogens, molecules derived from host proteins, and toxic insults (e.g., alcohol exposure). Clinicians should screen all patients for harmful patterns of alcohol use. All patients with alcohol-related liver disease should abstain from alcohol. For those with severe disease (ie, DF ≥32 or hepatic encephalopathy or both), and no contraindications to their use, steroids should be considered.

While the early stages may have no symptoms, later stages can cause symptoms such as fatigue, swelling in the hands and legs, jaundice, loss of appetite, and weakness. While treating ALD it is important not only to abstain from alcohol but also become conscious of other factors that could affect the liver. Many people with ALD are malnourished (lacking proper nutrition) due to a variety of factors, such as lack of eating, vomiting, and malabsorption (difficulty absorbing nutrients from food). In general, the more severe the ALD, the more malnourished someone becomes.
- People with cirrhosis who stop drinking alcohol live longer than those who continue drinking.
- However, more data on the efficacy of N-acetylcysteine in severe AH patients are needed before recommending its routine use in practice.
- But you could develop alcohol-related cirrhosis without ever having alcohol-related hepatitis.

The single best treatment for alcohol-related liver disease is abstinence from alcohol. When indicated, specific treatments are available that can help people remain abstinent, reduce liver inflammation, and, in the case of liver transplantation, replace the damaged liver. Chronic drinking can also result in a condition known as alcohol-related liver disease.
News from Mayo Clinic
- What factors trigger KC activity in patients with alcohol use disorder?
- Steatosis is the earliest, most common response that develops in more than 90 percent of problem drinkers who consume 4 to 5 standard drinks per day over decades (Ishak et al. 1991; Lieber 2004).
- About 10% to 20% of patients with alcoholic hepatitis are likely to progress to cirrhosis annually, and 10% of the individuals with alcoholic hepatitis have a regression of liver injury with abstinence.
After a brief overview of alcohol metabolism in the liver, this article will summarize the mechanisms through which excessive alcohol consumption contributes to the development of various types of alcohol-induced liver damage. It also will review modifiers of alcoholic liver disease (ALD) and discuss currently used treatment approaches for patients with ALD. This procedure remains the standard of care for patients with end-stage liver disease. As a result, transplantation candidates with ALD often are screened for common malignancies and must undergo a formal medical and psychiatric evaluation.

Doctors may also recommend weight loss and quitting smoking as excess weight and smoking have both demonstrated a role in worsening alcoholic liver disease. Those who regularly drink more than the recommended daily limits of alcohol should not stop drinking without medical support. Individuals should seek help from a medical professional to safely manage alcohol withdrawal. The first step in treating any level of alcoholic liver disease focuses on removing alcohol from the diet.
The disease burden of alcohol is rapidly increasing in Asian countries such as China, Korea, and India. There are also regional differences in Europe between Eastern and Western Europe, likely to be due to implementation of policy measures leading to decrease in alcohol use in many areas of Western Europe. There appears to be a threshold effect above which the amount and duration of alcohol use increases the risk of the development of liver disease. That threshold is not known and varies by individual risk factors (1). Innate immunity is the first line of antiviral protection in the liver. HCV commandeers this line of defense, and ethanol metabolism potentiates its takeover.
