In an era where socializing, working after hours, or drinking to relax has become normal for working adults, many may not realize that &#8220;alcohol drinking behavior&#8221; is quietly affecting liver health.
&nbsp;
One of the continuously increasing diseases is Alcoholic Fatty Liver Disease, which often has no clear symptoms in the early stages. However, if left without behavioral adjustment, it may develop into hepatitis, cirrhosis, and even liver cancer in the long term.
&nbsp;
This article will help you understand how heavy alcohol consumption is related to fatty liver, who is at risk, and when you should have your liver health checked.
&nbsp;
<h2>What is Fatty Liver?</h2>
Fatty Liver Disease is a condition where there is an abnormal accumulation of fat in liver cells. Generally, if fat accumulates in the liver exceeding 5–10% of the liver&#8217;s weight, it is considered the beginning of fatty liver disease. This disease can be divided into two main groups:
<ol>
<li>Alcoholic Fatty Liver Disease caused by drinking large amounts of alcohol or drinking over a long period.</li>
<li>Non-Alcoholic Fatty Liver Disease (NAFLD) often associated with obesity, diabetes, or insulin resistance.</li>
</ol>
Although both types have different causes, if left untreated, they can lead to severe liver disease.
&nbsp;
<h2>Why does heavy alcohol drinking cause fatty liver?</h2>
When the body receives alcohol, the liver plays a major role in eliminating and metabolizing alcohol. However, this process causes changes in fat metabolism, leading to increased fat accumulation in liver cells. The mechanisms causing alcoholic fatty liver include:
<ul>
<li>The liver uses a large amount of energy to eliminate alcohol</li>
<li>Fat metabolism decreases</li>
<li>Increased fat production in the liver</li>
<li>Inflammation of liver cells</li>
</ul>
&nbsp;
If drinking continues for a long time, it may lead to the following sequence of liver diseases:
<ol>
<li>Fatty liver</li>
<li>Alcoholic hepatitis</li>
<li>Cirrhosis</li>
<li>Liver cancer</li>
</ol>
&nbsp;
<h2>How much drinking is risky for liver disease?</h2>
The amount of alcohol considered risky for liver health is generally:
<ul>
<li>Men: more than 2 standard drinks per day</li>
<li>Women: more than 1 standard drink per day</li>
</ul>
&nbsp;
One standard drink is equivalent to:
<ul>
<li>About 330 ml of beer</li>
<li>About 150 ml of wine</li>
<li>About 45 ml of distilled spirits</li>
</ul>
&nbsp;
However, the risk of liver disease also depends on several factors such as:
<ul>
<li>Continuous drinking over a long period</li>
<li>Having obesity or diabetes</li>
<li>Genetics</li>
<li>High-fat diet</li>
<li>Insufficient rest and sleep</li>
</ul>
&nbsp;
<h2>Symptoms of fatty liver that should not be overlooked</h2>
In the early stages, fatty liver usually has no symptoms, causing many people to be unaware until the disease progresses to a severe stage. Possible but non-specific symptoms include:
<ul>
<li>Fatigue, easy tiredness</li>
<li>Tightness or discomfort in the right rib area</li>
<li>Bloating, abdominal fullness</li>
<li>Nausea</li>
<li>Easy weight gain</li>
</ul>
&nbsp;
In more severe stages, symptoms may include:
<ul>
<li>Yellowing of the skin and eyes</li>
<li>Abdominal swelling</li>
<li>Leg swelling</li>
<li>Loss of appetite</li>
</ul>
&nbsp;
<h2>Who should have their liver health checked?</h2>
Liver health screening helps detect abnormalities early, especially in high-risk groups such as:
<ul>
<li>Regular alcohol drinkers</li>
<li>People with obesity or high blood lipids</li>
<li>People with diabetes</li>
<li>Those with a family history of liver disease</li>
<li>Those with symptoms of abdominal tightness or abnormalities in the right rib area</li>
</ul>
&nbsp;
<h2>Methods for diagnosing fatty liver</h2>
Since fatty liver disease in the early stages often shows no clear symptoms, health screening is very important, especially for those who regularly consume alcohol or have health risk factors. Doctors may consider multiple tests together to assess liver health, including:
&nbsp;
1. Blood test for liver function (Liver Function Test) Blood tests are a basic step to evaluate liver function and inflammation but cannot confirm fatty liver. Doctors will look at values such as:
<ul>
<li style="list-style-type: none;">
<ul>
<li>ALT (Alanine Aminotransferase)</li>
<li>AST (Aspartate Aminotransferase)</li>
<li>ALP (Alkaline Phosphatase)</li>
<li>Bilirubin</li>
</ul>
</li>
</ul>
2. Abdominal ultrasound (Ultrasound Abdomen) Ultrasound is widely used to screen for fatty liver. Doctors use high-frequency sound waves to examine the liver structure, which can help assess whether:
<ul>
<li style="list-style-type: none;">
<ul>
<li>There is fat accumulation in the liver</li>
<li>The liver size is abnormal</li>
<li>There are other abnormalities such as masses or cysts</li>
<li>The liver is beginning to show signs of cirrhosis</li>
</ul>
</li>
</ul>
The advantage of this method is that it is painless and quick.
&nbsp;
3. Liver fibrosis assessment In some cases, doctors may recommend additional tests to evaluate whether there is fatty liver or liver fibrosis.
<ul>
<li style="list-style-type: none;">
<ul>
<li>FibroScan (Transient Elastography) This method is popular because it is easy, painless, and can accurately quantify fatty liver and liver fibrosis.</li>
<li>Elastography Ultrasound</li>
</ul>
</li>
</ul>
4. CT scan or MRI (in some cases) If more detailed evaluation is needed, such as detecting liver masses, doctors may consider the following tests:
<ul>
<li style="list-style-type: none;">
<ul>
<li>CT Scan</li>
<li>MRI</li>
</ul>
</li>
</ul>
5. Liver biopsy In some cases where diagnosis confirmation or severity assessment is needed, doctors may consider a liver biopsy by taking a small liver tissue sample for laboratory examination, which can help evaluate:
<ul>
<li style="list-style-type: none;">
<ul>
<li>Whether there is liver inflammation and its cause</li>
<li>The amount of fat accumulation in the liver</li>
<li>Whether there is liver fibrosis or cirrhosis</li>
</ul>
</li>
</ul>
&nbsp;
<h2>Can fatty liver be treated?</h2>
The good news is that fatty liver in the early stages can return to normal if appropriate behavioral adjustments are made. Liver health care guidelines include:
<ul>
<li>Reducing or stopping alcohol consumption</li>
<li>Maintaining a healthy weight</li>
<li>Eating nutritious food, reducing fat and sugar intake</li>
<li>Exercising regularly</li>
</ul>
&nbsp;
Although alcohol drinking is part of many people&#8217;s lifestyles, heavy or continuous drinking over a long time may silently affect liver health. Fatty liver is a silent threat that, if detected early and treated along with proper behavioral adjustments, can reduce the risk of severe liver diseases such as hepatitis, cirrhosis, and liver cancer.
&nbsp;
If you regularly drink alcohol, are overweight, have diabetes, or have abnormal symptoms such as abdominal tightness, right rib pain, bloating, easy fatigue, yellowing of skin or eyes, or dark urine, consulting a liver specialist for liver health screening can help assess risks and plan appropriate care.
