In this video, consultant hepatologist Mark Wright explains liver disease and how not drinking alcohol can help. It’s generally not reversible, but stopping drinking alcohol immediately can prevent further damage and significantly increase your life expectancy. If someone with this condition has alcohol use disorder, a healthcare provider will need to set up a treatment plan. This plan will help manage the condition as well as the withdrawal symptoms that may occur with abstinence. Below, we’ll explore the early signs of alcohol-related liver disease, what alcohol actually does to your liver, and what steps you can take in your day-to-day life to improve your liver health.
Complications of alcohol-related liver disease
https://sober-home.org/alcohol-withdrawal/ (ALD) is caused by excessive alcohol consumption, which is defined as five or more drinks in a day or 15 or more drinks a week for men, and four or more drinks a day or eight or more drinks a week for women. About g/day in men and g/day in women for years is sufficient to cause liver damage in the absence of other liver diseases. To minimize the risk of recidivism, most transplant centers require a minimum of 6 months of abstinence before considering LT for a patient with ALD. However, patients with severe AH not responding to medical therapy cannot afford to meet this requirement given their short-term mortality at 1 month from presentation as high as 50% (96).
Liver Health During Treatment
Preventing decompensated cirrhosis may be possible, but it depends on the cause. If decompensated cirrhosis is triggered by something like an infection or your diet, the trigger can be identified, and the condition can be reversed or controlled, either with medical treatment or through lifestyle changes. The National Institute on Alcohol Abuse and Alcoholism defines heavy drinking as having 5 or more drinks in 1 day on at least 5 days out of the past month. Damage from prolonged alcohol misuse can lead to alcohol-related cirrhosis. When the liver tissue starts to scar, the liver doesn’t work as well as before.

Catalase normally carries out the detoxification of hydrogen peroxide (H2O2) to water and oxygen. However, when ethanol is present, catalase has an accessory role in ethanol metabolism by using H2O2 to oxidize ethanol to acetaldehyde. Ethanol oxidation by catalase is a relatively minor pathway in the liver, but has a larger ethanol-oxidizing function in the brain (Aragon et al. 1992). As emphasized in the most recent national practice guidelines, health care providers must be attentive for signs of covert alcohol abuse.18 Many patients do not openly disclose an accurate history of alcohol use. In addition, no physical examination finding or laboratory abnormality is specific for ALD. All patients should therefore be screened for alcohol abuse or dependency.
Alcoholic Liver Disease: Pathogenesis and Current Management
- The clinical course of ALD is influenced by alcohol abstinence ( 5,6 ).
- Patients initially exhibit active pericellular fibrosis, which may progress to cirrhosis, the late stage of hepatic scarring.
- Patients with alcoholic hepatitis are at risk of alcohol withdrawal.
- In addition to enhanced hepatic lipogenesis, fat (i.e., adipose) tissue contributes to the development of steatosis.
- Thus, 12 ounces (360 mL) of beer at 6 percent alc/vol, 5 ounces (150 mL) of wine at 12 percent alc/vol, or 1.5 ounces (45 mL) of distilled spirits at 40 percent alc/vol each are equivalent to a standard drink.

For example, if you’re a young adult, you may need to wait longer than an older adult, even if your medical needs are the same.

ASH, a term sometimes used to describe the histological features in AH, is diagnosed in patients with fatty liver disease when hepatic inflammation/damage or fibrosis is present on liver biopsy (Figure 2). Unfortunately, about half of the patients with seemingly early disease may already have advanced fibrosis or cirrhosis on liver biopsy (5). Of interest, patients with alcohol withdrawal syndrome (AWS) may have a higher prevalence of inflammation on liver biopsy than do patients without withdrawal syndrome (29). Patients can present with any or all complications of portal hypertension, including ascites, variceal bleeding, and hepatic encephalopathy. The histology of end-stage alcoholic cirrhosis, in the absence of acute alcoholic hepatitis, resembles that of advanced liver disease from many other causes, without any distinct pathologic findings (Figure 3).
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. Excessive alcohol consumption can cause fat to build up in your liver. This can lead to inflammation and an increase in scar tissue, which can seriously impact your liver’s ability to function as it should. Some people with severe alcoholic hepatitis may need a liver transplant.
Lifelong abstinence can improve liver function, but the permanent and severe damage from cirrhosis might mean that the person needs a liver transplant to survive. If a person continues to drink alcohol it will lead to ongoing liver inflammation. Alcoholic hepatitis is caused by damage to the liver from drinking alcohol. Just how alcohol damages the liver and why it does so only in some heavy drinkers isn’t clear. Your healthcare provider may also test you for individual nutrient deficiencies.
About 90% of heavy drinkers will develop alcoholic fatty liver disease. Taken together, these results strengthen the link of causality between alcohol use and progression of MASLD. The majority of AH patients have underlying macronodular cirrhosis, which is not easily distinguishable from other forms of cirrhosis. On electron microscopic examination, megamitochondria may be observed. If liver biopsy is performed for diagnosis of AH, the findings may also have prognostic value. For example, one recent study showed that presence of severe fibrosis, megamitochondria, degree of neutrophil infiltration, and cholestasis could predict prognosis in patients with AH (60).
Treatment also consists of evaluation for other risk factors that can damage the liver or put the liver at higher risk, such as infection with hepatitis C and metabolic syndrome. Alcohol abstinence is the first line of treatment, with periodic liver enzyme tests to monitor ongoing liver damage. Involvement of addiction specialists and incorporation of an addiction unit within the LT center is useful in reducing frequency of drinking and alcohol use disorder treatment recidivism compared to referring these patients to an outside center for addiction therapy (161). However, the patient’s degree of illness and transportation issues may be significant limiting factors in these patients’ ability to complete therapy sessions (40).

Hepatic fibrosis is a transient and reversible wound-healing response, which may be restored to normal in some patients if alcohol intake ceases. However, if drinking continues, chronic inflammation and sustained fibrogenesis progress, resulting in the substitution of liver parenchyma by scar tissue that severely compromises the liver’s vascular architecture. The main pathological feature of cirrhosis is https://sober-house.net/drinking-levels-defined-national-institute-on-2/ the formation of regenerative nodules of hepatic parenchyma surrounded by fibrous septa. Cirrhosis development progresses from a compensated phase, in which part of the liver remains undamaged and functionally compensates for the damaged regions, to a decompensated phase, in which scar tissue fully envelops the organ. The latter is characterized by development of portal hypertension and/or liver failure.
Drinking can also lead to injuries and death by accidents, including motor vehicle crashes and falls, and can result in social and legal problems. Acute alcoholic hepatitis can develop after as few as four drinks for women and five drinks for men. On average, 1 in 3 people with the most advanced stage of liver disease and cirrhosis are still alive after 2 years.
