The Surprising Causes and Risk Factors of Liver Disease


The Surprising Causes and Risk Factors of Liver Disease

You might think that you have an idea of what causes liver disease, but you could be surprised. While certain bad habits—like drinking alcohol, smoking, and taking certain drugs—can all cause liver damage, there are many more risks that might surprise you.

From being exposed to certain chemicals to inherited conditions, the causes of liver disease can vary widely. But no matter what the source, it’s important to understand the various risk factors associated with the condition so you can take steps to protect yourself.

In this article, we'll discuss some of the less obvious causes and risk factors that could be leading to liver disease—and how to monitor them. We'll also provide some helpful tips on how to recognize and manage liver damage if it does occur. Read on to learn more about why understanding these factors is so important!

What Is Liver Disease?

If you think liver disease is a rare occurrence, think again. In the United States alone, millions of people suffer from some form of chronic liver disease each year. So what exactly is liver disease?

Simply put, liver disease is a broad term used to describe any condition or disorder that affects or damages the liver. There are many different types of liver diseases, but the most common form is cirrhosis—a type of irreversible damage to the organ that leads to its gradual deterioration. Other forms of liver disease include hepatitis, fatty liver disease, and biliary cirrhosis.

All forms of liver disease can have long-term health complications and are often life-threatening conditions. That's why it's important to be aware of the risk factors and causes associated with this condition so you can catch it early and get treatment right away.

Common Causes of Liver Disease

Liver disease can develop as a result of a variety of factors, some of which might come as a surprise to you. Some of the more common causes include:

  • Excessive or sustained alcohol consumption: Alcohol abuse is one of the most common causes of liver disease. The liver can only process a certain amount of alcohol and when the limit is exceeded, serious toxicity occurs that can ultimately lead to permanent damage.

  • Medications & chemicals: Certain medications and chemicals, such as acetaminophen, Tylenol and ibuprofen, are also known to damage the liver if taken excessively. Additionally, exposure to certain chemicals like pesticides and paint fumes can also contribute to liver damage.

  • Viruses & infections: Viral hepatitis B and C can cause extensive damage to the liver over time. Additionally, other viral infections like herpes simplex virus and Epstein-Barr virus have been linked to liver disease in extreme cases.

  • Genetics & environment: Genetic factors such as hemochromatosis (an inherited disorder that causes your body to absorb and store too much iron), metabolic disorders (such as Wilson's Disease) or autoimmune diseases (like primary biliary cirrhosis) can also increase your risk for developing liver disease. Additionally, your environment may be contributing to your risk if you are exposed routinely to toxins or pollutants in the air or soil.

These cases are far from exhaustive—other medical conditions such as obesity, diabetes or heart failure could also indicate an elevated risk for developing liver disease. It's important to speak with your doctor if you suspect any underlying issues that may put you at an increased risk for developing this potentially deadly condition.

Different Types of Liver Diseases

Did you know there are different types of liver diseases? Sure, they're all known as liver disease, but there are actually different categories of it. Here they are:


This is an inflammation of the liver that can be caused by a virus, like what happens when you get a stomach bug. It can also be caused by certain medications and alcohol overuse. The good news is that hepatitis can often be cured or managed.

Alcoholic Liver Disease

As the name implies, this type of liver disease is caused by excessive alcohol consumption and over time, can cause serious damage to your liver. It's important to note that it’s not just heavy drinking that causes this—it's also how often you drink and how long you've been drinking for. Some people may become affected after only a few years of regular drinking.

Non-Alcoholic Fatty Liver Disease (NAFLD)

The most common type of liver disease, NAFLD doesn’t involve any alcohol use. Instead, this condition is caused by the buildup of extra fat in the organ due to genetics or lifestyle factors like being overweight or having diabetes. It can range from mild to severe and may cause other health problems if left untreated.

Whatever type of liver disease you might have, it’s important to understand what might have led to it and to know your risk factors so that you can take proactive steps to care for yourself and your liver health going forward.

Risk Factors for Liver Disease

There are several risk factors for developing liver disease. While some of these can be changed, like obesity, others can’t be, like genetics. Here are a few risk factors to keep in mind:


Obesity is one of the leading cause of liver disease, as too much fat on the body puts stress on the liver and can cause inflammation and scarring.

Excessive Alcohol Consumption

Drinking too much alcohol over a long period of time can lead to fatty liver disease, cirrhosis and other forms of liver damage.

Viral Infection

Having certain viruses in your system increases your risk for liver disease—hepatitis A, B, or C viruses are some of the most common culprits linked to this type of illness.

Genetics & Family History

Genetics can play a role in increased risk for developing liver diseases such as hemochromatosis or Wilson’s Disease. Also if you have family members who have had liver issues in the past, you may be more at risk than others.

Knowing these risk factors helps you to make informed decisions about your lifestyle choices. Eating a healthful diet, maintaining an active lifestyle and avoiding excessive alcohol consumption could help to reduce your chances of developing harmful conditions such as fatty liver disease and cirrhosis.


All in all, there are a lot of risk factors and causes to consider when it comes to liver disease, and it's important to be aware of them and know the signs of liver damage. It's also important to understand that it is possible to prevent and even reverse liver disease by making lifestyle changes such as eating a healthy diet, exercising regularly, cutting back on alcohol consumption, and avoiding excessive medications and supplements.

If you are concerned about your own risk of liver disease, or if you have already been diagnosed, it is important to speak to your healthcare provider to discuss the best approach to treatment and management. Taking the right steps today can go a long way in protecting your long-term health.
