Alcohol related liver disease

Overview

Alcohol-related liver disease (ARLD) is damage to your liver caused by drinking too much alcohol over a long time. The liver is an organ that helps filter your blood, digest food, and store energy. When you drink heavily or often, alcohol can slowly injure the liver cells, leading to inflammation, scarring, and eventually the liver may stop working properly.

Yes, alcohol-related liver disease is one of the most common causes of liver damage in the UK and many other countries. It affects millions of people, but many do not have symptoms until the liver is already seriously damaged.

It mostly affects adults in their 40s and 50s, but it can happen at any age if alcohol is misused. Men are more likely to develop the condition, but women are more sensitive to alcohol's harmful effects and can develop liver disease at lower drinking levels. The risk is higher for people who drink heavily every day or binge drink regularly.

Symptoms

Common symptoms

• Feeling very tired
• Loss of appetite and weight loss
• Feeling sick (nausea) or being sick
• Pain or discomfort in the upper right side of your tummy (abdomen)
• Swelling in your legs, ankles, or tummy (oedema and ascites)
• Jaundice – yellowing of your skin or the whites of your eyes
• Itchy skin
• Dark urine or pale stools (poo)

Symptoms in children

• Children do not normally get alcohol-related liver disease because they rarely drink enough to cause damage. However, if a teenager heavily misuses alcohol, similar symptoms can appear: tiredness, tummy pain, jaundice, or swelling.

Symptoms in older adults

• Older adults may have the same symptoms, but they can be harder to spot because they might be mistaken for other age-related problems. For example, confusion or forgetfulness can happen from liver problems as well as aging. Falls and frailty may also be signs.

Causes

Main causes

• Long-term heavy alcohol use – drinking more than the recommended limits for many years (for example, more than 14 units of alcohol per week for both men and women is considered risky).
• Binge drinking – consuming a large amount of alcohol in a short time repeatedly.

Risk factors

• Drinking alcohol regularly and heavily over many years
• Being a woman – women absorb more alcohol and are more vulnerable to liver damage at lower drinking levels
• Having a family history of liver disease or alcohol misuse
• Being overweight or obese – this adds extra stress on the liver
• Having hepatitis C or other viral hepatitis infections – these can combine with alcohol to damage the liver faster

When to see a doctor

See a doctor urgently if:

• Any symptoms of jaundice – yellow skin or eyes
• Vomiting blood or passing dark, tarry stools
• Sudden confusion or drowsiness
• Severe pain or swelling in your tummy

Book a routine appointment if:

• If you have been drinking heavily for a long time and are worried about your liver health
• Ongoing tiredness, poor appetite, or vague tummy discomfort
• If you have a history of alcohol misuse and want advice on how to stop or reduce drinking

Diagnosis

Your doctor will ask about your drinking habits, symptoms, and medical history. They will examine you to check for signs like an enlarged liver, swelling, or jaundice. Blood tests are usually done first to see how well your liver is working.

Tests that may be done

• Blood tests (liver function tests) – measure enzymes and proteins in your blood that show liver damage
• Ultrasound scan – a painless test that uses sound waves to create images of your liver
• FibroScan – a special ultrasound that measures how stiff your liver is (stiffness means scarring)
• Liver biopsy (sometimes) – a tiny sample of liver tissue is taken to check for inflammation and scarring

What to expect at your appointment

If your doctor suspects ARLD, they will arrange blood tests and an ultrasound. These are usually done as an outpatient. If tests show advanced disease, you may be referred to a liver specialist. The process can be worrying, but the sooner you know, the better the chances of improving your health.

Treatment

The most important treatment for alcohol-related liver disease is to stop drinking alcohol completely. This can help reverse damage in the early stages and prevent the disease from getting worse. Medical treatment focuses on managing symptoms, preventing complications, and supporting your overall health.

Self-care at home

• Stop drinking alcohol completely – your doctor or local addiction service can help you with this
• Eat a healthy, balanced diet with plenty of fruits, vegetables, and protein
• Drink enough water each day
• Get enough rest and try to stay physically active within your limits
• Avoid taking any medicines or supplements that can harm the liver, like paracetamol, without your doctor's advice

Medical treatments

If you stop drinking, your doctor may prescribe medications to help with alcohol withdrawal and cravings. For inflammation or complications like infection or fluid buildup (ascites), treatments such as steroids or diuretics may be used, but always under specialist care. In advanced cirrhosis, you may need regular hospital visits for monitoring and management of complications.

When is surgery considered?

In very severe cases where the liver is failing and no other treatments have worked, a liver transplant may be considered. You must be completely alcohol-free for at least 6 months (usually) to qualify for a transplant. Surgery is a major operation with many risks and a long recovery.

Living with this condition

Living with ARLD means making long-term changes. You will need to stay completely away from alcohol. You may need to follow a special diet low in salt to reduce fluid buildup. Regular check-ups with your doctor are important to monitor your liver and manage any symptoms.

Lifestyle tips

• Avoid all alcohol – this is the most important step
• Take all prescribed medications exactly as directed
• Get help for alcohol addiction through counselling or support groups
• Maintain a healthy weight – extra fat can worsen liver damage
• Get vaccinated against hepatitis A and B if your doctor recommends it (these infections are harder on a damaged liver)

Diet and exercise

Eat small, frequent meals that are high in protein and low in salt. Avoid processed foods, fried foods, and sugary drinks. Gentle exercise like walking or stretching can help maintain muscle strength and mood, but listen to your body and rest when needed.

Mental health and emotional wellbeing

Living with a chronic liver condition can be stressful and may lead to anxiety or depression. It is normal to feel overwhelmed, especially if you are also dealing with alcohol dependence. Talk to your doctor about mental health support – counselling, therapy, and support groups can help.

Prevention

Yes, ARLD can be prevented by drinking alcohol in moderation or not drinking at all. For adults who choose to drink, the UK guidelines recommend no more than 14 units of alcohol per week (spread over 3 or more days) and having several alcohol-free days each week.

Vaccines

While there is no vaccine for ARLD, getting vaccinated against hepatitis A and B can protect your liver from additional infections that could make liver disease worse. Talk to your doctor about whether these vaccines are right for you.

Screening programmes

If you have a history of heavy drinking or are at high risk, your doctor may recommend regular liver function tests to catch any damage early. Screening is part of routine care for some people.

Complications

If left untreated

• Cirrhosis – permanent scarring of the liver that stops it working properly
• Liver failure – when the liver can no longer do its job, which can be life-threatening
• Ascites – fluid buildup in the tummy, which can lead to infections
• Varices – enlarged veins in the food pipe that can burst and cause severe bleeding
• Hepatic encephalopathy – a buildup of toxins that affects the brain, causing confusion or coma
• Increased risk of liver cancer

Long-term outlook

The outlook depends on the stage of disease when diagnosed. For fatty liver and mild alcoholic hepatitis, stopping alcohol completely can often reverse the damage. Even with cirrhosis, many people live for years with good management. The key is to stop drinking and follow medical advice. With support, many people improve their quality of life significantly.
