Both liver diseases are generally related to unhealthy lifestyle habits, including excessive alcohol and food intake, and both are likely to be serious health problems in the future. In contrast to chronic viral liver diseases, ALD and NAFLD are frequently accompanied by extrahepatic diseases that can influence patient survival. A comprehensive understanding of these diseases is essential for their management. Patients that develop severe AH usually require hospitalization for initial management. Primary prevention is aimed at alcohol abstinence; active management of alcohol use disorders is critical to achieving continued abstinence. For the successful management of these patients, a multidisciplinary team composed of hepatologists, psychologists, psychiatrists and social workers is highly recommended29.
If you are a heavy drinker, experts recommend having specific blood tests that can determine if your liver is functioning normally. Other noninvasive tests may also be ordered, such as an ultrasound of your liver, to further evaluate its condition. ALD and NAFLD are frequently accompanied by extrahepatic complications. Therefore, we compared the comorbidities of patients with these two types of liver disease. A large cohort study found that type 2 diabetes and/or IR were independent predictors of overall mortality in patients with both ALD and NAFLD. Furthermore, type 2 diabetes, IR, obesity, and metabolic syndrome were independent predictors of liver-related mortality in both patient subsets103.
Untreated Alcoholic Liver Disease Complications
- While it may be reasonable to assume that the risk increases with the amount of alcohol you drink, factors like genetics, sex, and weight can predispose you to severe hepatitis at far lower levels.
- Getting adequate proteins, calories, and nutrients can alleviate symptoms, improve quality of life, and decrease mortality.
- Alcoholic fatty liver is generally a benign condition which is reversible by eliminating consumption of alcohol.
Most transplantation alcoholic liver disease centers require 6-months of sobriety prior to be considered for transplantation. This requirement theoretically has a dual advantage of predicting long-term sobriety and allowing recovery of liver function from acute alcoholic hepatitis. This rule proves disadvantageous to those with severe alcoholic hepatitis because 70% to 80% may die within that period. Mathurin et al found that early liver transplant in patients with severe alcoholic hepatitis versus those who were not transplanted had higher 6-month survival, and this survival benefit was maintained through 2 years of follow-up. Relapse after transplantation appears to be no more frequent than it is in patients with alcoholic cirrhosis who do not have alcoholic hepatitis. The causes of death have been found to differ in patients with ALD and NAFLD.

Although few studies to date have directly compared the outcomes of patients with ALD and NAFLD, we have delineated the characteristics of the reported outcomes (Table 4). Transient elastography has also been shown to be useful in assessing the disease stage. Generally, transient elastography cannot differentiate simple hepatic steatosis from mild hepatic fibrosis but can assess the degree of hepatic fibrosis. Liver biopsy, while not always necessary, can help to differentiate simple steatosis from steatohepatitis, fibrosis or incipient cirrhosis. Precise definition of the liver fibrosis stage is essential for management and prognosis in clinical practice.
Alcoholic hepatitis (Alcohol-associated hepatitis)
Swelling in the legs and ankles can occur due to fluid retention caused by liver dysfunction. It is important to note that these symptoms can vary in severity depending on the stage of Alcoholic Liver Disease and individual factors such as overall health and alcohol consumption patterns. If you or someone you know is experiencing any combination of these symptoms, it is crucial to seek medical attention promptly for proper diagnosis and treatment options.

There are normally no symptoms, and alcoholic fatty liver disease is often reversible if the individual abstains from alcohol from this point onward. Although alcoholic beverages contain calories, research suggests that under certain conditions these calories do not have as much value for the body as those derived from other nutrients. In addition, many alcoholics suffer from malnutrition, which can lead to liver damage and impaired liver function. Many drinkers take in less than the recommended daily amount of carbohydrates, proteins, fats, vitamins (A, C, and B, especially thiamine B1), and minerals (such as calcium and iron). Outside medical treatment, patient education is the key to treatment for patients with alcoholic liver disease.
Differential Diagnosis
It’s important to note that taking vitamin A and alcohol together can be deadly. Supplements will not cure liver disease, but they can prevent complications like malnutrition. Alcohol-related liver disease (ARLD) is caused by damage to the liver from years of excessive drinking. Of the three enzymes, GGT is the best indicator of excessive alcohol consumption, but GGT is present in many organs and is increased by other drugs as well, so high GGT levels do not necessarily mean the patient is abusing alcohol.
Preventing Alcoholic Liver Disease
Lorazepam and oxazepam are the preferred benzodiazepines for prophylaxis and treatment of alcohol withdrawal. Documentation of daily caloric intake is necessary for patients with alcoholic hepatitis, and nutritional supplementation (preferably by mouth or nasogastric tube) is an option if oral intake is less than 1200 kcal in a day. Cirrhosis is the most advanced stage of alcohol-related liver disease. It prevents the liver from what is alcoholism working properly, and it cannot be reversed. Some people have both alcoholic hepatitis and cirrhosis at the same time.
Treatment for ALD focuses on stopping alcohol use, managing symptoms, and preventing further liver damage. Patients with DF ≥ 32 or MELD score ≥ 21 should be considered for clinical trial enrollment if available. If a clinical trial is not available, a trial of glucocorticoid treatment is reasonable. The Lille score is designed to determine whether patients treated with corticosteroids should stop treatment after 1 week of treatment due to lack of treatment response. It is a good predictor of 6 months mortality and those with a score of less than 0.45 are considered to have a good prognosis and treatment with corticosteroids should be continued.
If you or someone you know struggles with alcohol-related health concerns, seek medical guidance to explore treatment options and begin the journey to recovery. In general, the risk of liver disease increases with the quantity and duration of alcohol intake. The quantity of alcohol in alcoholic beverages varies by volume base on the type of beverage (Table 2). If a person experiences changes in the genetic profiles of particular enzymes that are key to alcohol metabolisms, such as ADH, ALDH, and CYP4502E1, they will have a higher chance of developing alcoholic liver disease. Acute alcoholic hepatitis can develop after as few as four drinks for women and five drinks for men. Drinking history is an essential component, which includes the number of drinks per day and the duration of drinking.
Most research employs animal models, primarily exhibiting signs of moderate ALD, such as steatosis and mild inflammation 89. However, there is a lack of models encompassing advanced fibrosis and cholestasis, two key histological features in the evolution from early to advanced ALD. Although corticosteroids are the most extensively studied form of therapy for alcoholic hepatitis, their usefulness may be only short-term.
When exposed to persistent inflammation, HSCs overproduce collagen, causing a tangle of cells that progressively scar and damage the liver. While hepatosteatosis is largely asymptomatic (without symptoms), the underlying inflammation can build as the fatty deposits increase, eventually leading to symptoms of hepatitis. Moderate alcohol consumption for women means that no more than one alcoholic beverage is consumed each day. Moderate alcohol consumption for men means that no more than two alcoholic beverages are consumed each day. Early diagnosis and intervention can significantly improve outcomes and prevent further liver damage.
