Drinking excessive amounts of alcohol can have both short and long-term effects on your health and wellbeing, including causing liver damage. Although your liver can regenerate, repeated damage can cause healthy tissue to be replaced with scar tissue. As the amount of scar tissue increases, the function of your liver can decrease.
A leading cause of liver damage is long-term alcohol misuse, which can lead to alcohol-related liver disease. Your liver has the ability to regenerate in response to damage but repeated damage causes scar tissue to build up, which over time can impair your liver function.
Regularly drinking too much alcohol puts a strain on your liver, which is responsible for processing alcohol by breaking it down. The byproducts of the breakdown of alcohol are what damage your liver.
Alcohol-related liver damage initially causes fat to accumulate in your liver, followed by inflammation and finally the build-up of scar tissue.
What are the first signs of liver damage?
In the early stages, you may not be aware that you have alcohol-related liver disease as it doesn’t often cause symptoms initially. However, as the condition progresses, you may experience:
Risk factors for liver damage
Risk factors for developing alcohol-related liver disease include:
Regularly drinking excessive amounts of alcohol increases your risk of liver cirrhosis (long-term liver damage and scarring), which subsequently increases your risk of liver cancer.
In the early stages, liver cancer often doesn’t cause any symptoms. However, as the condition progresses, you may experience:
If you have liver cirrhosis or another liver condition and you notice any of the above symptoms, new symptoms or worsening symptoms, see your doctor.
Risk factors for liver cancer
Seven in every 100 cases of liver cancer in the UK are caused by excessive alcohol consumption. The more alcohol you consume, the higher your risk of liver cancer. Research has shown drinking 4.5 units of alcohol or more every day increases your risk by 16%, while drinking six units of alcohol or more every day more than doubles your risk when compared with non-drinkers or occasional drinkers.
Reducing how much alcohol you drink will improve your liver health. There are several other steps you can take to improve your liver health, including:
How much alcohol will damage your liver?
Drinking in moderation (ie less than 14 units of alcohol per week spread over at least three days with several alcohol-free days) can increase fat levels in your liver. However, liver damage usually only occurs if you drink in excess ie more than 14 units per week and/or regularly binge drink.
What are signs that your liver is struggling?
Signs that your liver may be damaged include abdominal swelling, discomfort and/or pain, nausea and vomiting, loss of appetite, tiredness and unexplained weight loss.
How do I know if my liver is OK?
Liver damage often doesn’t cause any symptoms in the early stages. If you are concerned about the health of your liver, see your doctor. Depending on your medical history and levels of alcohol consumption, they may recommend an ultrasound scan of your liver to check its health.
What alcohol is easy on the liver?
All types of alcohol place a strain on your liver as your liver is responsible for breaking down alcohol. If you are a regular drinker, you should, therefore, incorporate several alcohol-free days into your week to give your liver a chance to rest and recover. You should also avoid drinking more than 14 units of alcohol per week and should spread these units out over at least three days.
Does your liver get better if you stop drinking?
Yes, your liver can get better if you stop drinking as it can regenerate. However, in very advanced cases of alcohol-related liver disease, your liver may not be able to recover.
