Beer Drinking And Liver Cirrhosis: What's The Link?

Alcohol is a major risk factor for liver disease and can cause severe damage to the liver. The liver is an organ that sits on the upper right side of the abdomen and is responsible for filtering waste, making bile to aid digestion, storing sugar and making proteins that are important for blood clotting. When a person drinks alcohol, the liver breaks it down. However, when a person drinks more than the liver can process, it can become badly damaged. This initially takes the form of increased fat in the liver, but over time it can lead to inflammation and the accumulation of scar tissue. This can impair the liver's ability to function properly.

Alcohol-related liver disease can progress through three types of conditions: steatotic (fatty) liver, acute hepatitis, and cirrhosis. Steatotic liver is the most common alcohol-induced liver problem and is characterised by a build-up of fat inside liver cells, which can lead to an enlarged liver. Alcoholic hepatitis is an acute inflammation of the liver, which can be followed by permanent scarring. Alcohol-associated cirrhosis is the destruction of normal liver tissue, leaving scar tissue in its place. In this situation, the liver may stop working correctly.

The amount of alcohol consumed, as well as the duration of consumption, influences the risk of developing alcohol-related liver disease. Binge drinking, defined as consuming more than four standard drinks for women or more than five standard drinks for men on a single occasion, can lead to liver damage. According to the National Institute of Alcohol Abuse and Alcoholism, a standard drink contains about 0.6 fluid ounces or 14 grams of pure alcohol. For cirrhosis to develop in men, a person must drink more than about 3 ounces of alcohol a day for more than 10 years. Women may develop liver cirrhosis if they drink half the amount of alcohol as men, or more than 1.5 ounces of alcohol a day for several years.

It is important to note that there is no safe amount of alcohol that can be consumed by patients with cirrhosis, and complete abstinence is recommended. Early-stage liver disease is fully reversible once alcohol consumption is stopped. However, if the disease progresses to cirrhosis, the chances of recovery are decreased, and liver transplantation may be necessary in advanced cases.

Alcoholic hepatitis

The National Institute on Alcohol Abuse and Alcoholism (NIAAA) defines alcoholic hepatitis as including the following:

• The onset of jaundice within 60 days of heavy alcohol consumption (more than 50 g/day) for a minimum of 6 months
• Serum bilirubin more than 3 mg/dL
• Elevated aspartate aminotransferase (AST) to 50 U/L to 400 U/L
• AST:ALT (alanine aminotransferase) ratio of more than 1.5
• No other cause of acute hepatitis

The progression of alcoholic hepatitis can be slowed or halted by discontinuing alcohol consumption. However, the cirrhosis that has already occurred will not reverse. Abstinence, along with adequate nutritional support, is the cornerstone of managing alcoholic hepatitis. For severe cases of alcoholic hepatitis, short courses of prednisolone or methylprednisolone may be prescribed.

Alcoholic cirrhosis

The liver has a wide variety of functions, including filtering waste from the body, producing bile to aid digestion, and storing sugar that the body uses for energy. When the liver is damaged, it can result in a range of symptoms, including abdominal discomfort, jaundice, gastrointestinal bleeding, and increased infections.

The treatment for alcoholic cirrhosis aims to restore some or all of the liver's normal function. This primarily involves stopping alcohol consumption completely, which can often allow the liver to heal and return to normal. However, in severe cases, a liver transplant may be necessary.

It is important to note that not all heavy drinkers will develop alcoholic cirrhosis, and the risk increases with the amount of alcohol consumed and the duration of drinking. Additionally, women may develop the disease after less exposure to alcohol than men.

Alcoholic fatty liver disease

Fatty liver disease is characterised by a build-up of fat inside liver cells, which leads to an enlarged liver. It is the most common alcohol-induced liver problem and often has no symptoms. However, it can cause upper belly discomfort on the right side and tiredness and weakness.

The condition is reversible, and if you stop drinking alcohol for some time (months or years), your liver should return to normal. However, it is important to note that alcoholic fatty liver disease can progress to the next stages of alcohol-related liver disease: alcoholic hepatitis and cirrhosis.

Alcoholic hepatitis is a potentially serious condition caused by alcohol misuse over a long period. It involves the death of liver cells, often followed by permanent scarring. The liver damage associated with mild alcoholic hepatitis is usually reversible if you stop drinking permanently. However, severe alcoholic hepatitis is a life-threatening condition.

Cirrhosis is a stage of alcohol-related liver disease where the liver has become significantly scarred, and there may still be no obvious symptoms. It is generally not reversible, but stopping drinking alcohol immediately can prevent further damage and increase life expectancy.

The treatment for alcoholic fatty liver disease and other forms of alcohol-related liver disease is to stop drinking alcohol completely. Participating in an alcohol use disorder treatment program can help achieve this goal. With complete alcohol avoidance and time, the liver can often heal, allowing a return to a normal life. However, when liver tissue loss is severe enough to cause liver failure, a liver transplant may be required.

Liver cancer

Primary liver cancer can occur in both adults and children, with hepatocellular carcinoma and bile duct cancer being the main types of adult primary liver cancer. Most adult primary liver cancers are hepatocellular carcinomas, making this type the third leading cause of cancer-related deaths worldwide.

Risk Factors and Prevention

Several factors can increase the risk of developing liver cancer, including:

• Being overweight or obese
• Long-term hepatitis B or C virus infection
• Cirrhosis, which can be caused by hepatitis or alcohol use
• Non-alcoholic fatty liver disease
• Haemochromatosis, a condition where the body stores excess iron
• Eating foods containing aflatoxin, a fungus that can grow on improperly stored grains and nuts

To lower the risk of liver cancer, it is recommended to maintain a healthy weight, get vaccinated against hepatitis B, get tested and treated for hepatitis C, avoid excessive alcohol consumption, and refrain from smoking.

Symptoms of Liver Cancer

• Discomfort or pain in the upper abdomen, particularly on the right side
• A hard lump below the rib cage on the right side
• Pain near the right shoulder blade or in the back
• Jaundice, or yellowing of the skin and eyes
• Easy bruising or bleeding
• Nausea and vomiting
• Unexplained weight loss

Liver failure

Alcohol consumption is one of the leading causes of liver damage. When the liver is overwhelmed by excessive alcohol intake, it can lead to a condition known as alcoholic liver disease, which encompasses three stages:

• Steatotic (Fatty) Liver: This is the most common alcohol-induced liver problem. It occurs when fat accumulates inside the liver cells, leading to an enlarged liver.
• Alcoholic Hepatitis: Prolonged alcohol abuse can cause inflammation of the liver, resulting in cell death and permanent scarring.
• Alcoholic Cirrhosis: This is the most severe form of alcoholic liver disease. It involves the destruction of normal liver tissue, which is replaced by scar tissue. The liver's function deteriorates, and it may eventually stop working correctly.

The progression of alcoholic liver disease is strongly linked to the amount and duration of alcohol consumption. According to the National Institute of Alcohol Abuse and Alcoholism, heavy alcohol use is defined as consuming more than 14 drinks per week for women and more than 21 drinks per week for men. Binge drinking, which is consuming more than four drinks for women or five drinks for men on a single occasion, can also lead to liver damage.

The symptoms of alcoholic liver disease vary depending on the stage. In the early stages, individuals may experience upper abdominal discomfort, fatigue, and unexplained weight loss. As the disease progresses to hepatitis and cirrhosis, additional symptoms may include:

• Yellowing of the skin and eyes (jaundice)
• Abdominal pain and swelling
• Swollen legs and ankles
• Nausea and vomiting
• Easy bruising
• Disorientation and confusion
• Weakness and fatigue
• Pale, bloody, or dark stool

It is important to note that alcoholic liver disease is preventable and treatable. The most crucial step in treating this condition is complete abstinence from alcohol. With abstinence, the liver can often heal and regenerate, reversing some of the damage caused by alcohol. However, if the disease progresses to cirrhosis, the damage may become irreversible, and a liver transplant may be necessary.

In addition to abstinence, other treatment options for alcoholic liver disease may include dietary changes, medications to reduce inflammation, and, in severe cases, a liver transplant. It is essential to seek medical help if you or someone you know exhibits any signs or symptoms of alcoholic liver disease.
