How Do You Know If You Have Liver Damage From Alcohol? Here Are the Signs to Look for

It can be easy to lose count of how many drinks you’ve had when you’re out socializing or trying to relax. Although drinking in moderation is unlikely to cause liver damage, drinking large amounts of alcohol for longer periods of time may hurt your liver.

Here, we explore the different ways that alcohol can damage the liver. We’ll also explain some of the early signs of liver damage and what you can do if you’re worried about your liver health.

How does alcohol cause liver damage?

Your liver helps break down alcohol. This process creates substances that can harm the liver. Sometimes the liver can heal from minor damage. But as you drink more alcohol — and if you drink it frequently — the damage builds up.

There are three main types of liver damage from alcohol: alcoholic hepatitis, alcoholic liver disease, and cirrhosis. There may be some overlap between the types. So, someone can have more than one at the same time.

What are the first signs of liver damage from alcohol?

When liver damage from alcohol first starts to develop, it often doesn’t cause any symptoms. The only way to know it’s happening is through testing (which we describe below). When the first signs do eventually develop, they’ll look similar to liver damage from any cause.

Some of the first signs of liver damage include:

• Stomach pain (sometimes in the upper right part of your stomach)

• Unintended weight loss

• Decreased appetite

• Nausea

• Small, dilated blood vessels on the skin that are red and look like spiders (typically on the chest)

As the liver damage gets worse, you may notice other signs, such as:

• Swollen ankles and legs

• A firm or swollen feeling belly

• A yellow color on your skin or the white parts of your eyes

• A red color on your palms

• Poop that’s lighter in color than usual

But these symptoms generally don’t occur until the damage from alcohol has built up over a longer period of time.

Does liver damage from alcohol always cause symptoms?

As mentioned above, liver damage from alcohol starts well before symptoms begin to show up. But there are other ways to see if any liver damage has happened, even if you aren’t feeling symptoms. 

A healthcare professional can check certain tests that look at how your liver is functioning. These can include:

• Blood tests: Sometimes referred to as liver function tests (LFTs), these look at the level of certain enzymes in your liver. When these levels are elevated, it can be a sign of liver damage.

• Imaging tests: An ultrasound, CT, or MRI of the liver can tell you about the size and texture of your liver, and whether there are signs of damage. An ultrasound and MRI are most commonly used to directly assess liver health. But signs of liver damage can show up on a CT as well.

• Other tests: Other tests, like a liver biopsy, may be done in some cases (but less often). A liver biopsy is more helpful when it’s clear that someone has liver disease, but the cause is unclear. Most people with alcoholic liver disease don’t need this test.

It may feel scary to think you could have liver damage without even knowing it. Before any needless worry, let’s discuss just how much alcohol it takes to cause liver damage.

How much alcohol does it take to cause liver damage?

Having a drink every now and then doesn’t cause liver damage. Long-term, steady drinking is more likely to do this. Before we dive into how much alcohol it takes to cause damage, first let’s define what counts as “one drink.”

The CDC notes that one standard drink is defined as 0.6 oz (14 g) of alcohol. This is approximately the amount present in:

• 5 oz of wine (12% alcohol)

• 8 oz of malt liquor (7% alcohol)

• 12 oz of beer (5% alcohol)

• 1.5 oz of 80-proof liquor (40% alcohol)

With this in mind, most people with alcoholic liver disease report drinking at least 30 g of alcohol daily (about two drinks per day) over long periods of time (10 years or longer). And evidence shows that if a person drinks 80 g (around 6 drinks) daily for more than 10 years, there’s a nearly 100% chance they’ll develop alcoholic liver disease.

The best way to avoid any liver damage from alcohol is to not drink. But this doesn’t feel like a realistic goal for many people. To lower your risk, aim to drink alcohol in moderation. Dietary guidelines define “moderation” as:

• Fewer than two drinks a day for men

• Fewer than one drink a day for women

Also, avoid heavy drinking, which is defined as:

• 5 or more drinks on any day, or 15 or more in 1 week, for men

• 4 or more on any day, or 8 or more in 1 week, for women

If you’re still unsure or worried that you might have liver damage from alcohol, there are steps that you can take to determine risk, which we’ll cover next.

What to do if you’re worried about liver damage from alcohol

If you’re worried about liver damage from alcohol, a good first step is to make a plan to cut back. Or, stop drinking alcohol completely. This may feel hard — or even impossible — when you first think about it. That’s normal. But small changes in the right direction can make a big difference down the line. Even if you’ve consumed a lot of alcohol for a long time, cutting back at any point can still help.

The next step is to talk with a healthcare professional, like your primary care provider. They can help order the right tests for your liver, and talk about next steps to get help with alcohol use. There are even medications that can help, too.

Many people hesitate to be honest with their healthcare team about how much alcohol they drink, and this is understandable. Maybe you know it’s a problem, but don’t feel ready to change. Or maybe you don’t want to know if you have liver damage. Or maybe you just worry that you’ll feel judged. But rest assured that your healthcare team is there to support you, no matter where you are on that spectrum or what you feel ready for. It all starts with an honest conversation.
