If you feel mild pain or heaviness in the upper right side of the abdomen, then don’t ignore it. It can be a fatty liver. According to a 2023 meta-analysis published in Hepatology, fatty liver disease affects approximately 30% of adults worldwide. But what is fatty liver disease?
The liver is one of the main organs in your body that helps perform the main functions in your body, such as metabolism, detoxification, and digestion. A fatty liver is like a layer of fat on your liver that disrupts its normal operations, like how the liver cleans toxins, controls sugar and cholesterol, and helps with digestion, so it doesn’t work as smoothly as it should.
It usually happens because of an unhealthy diet, weight gain, and diabetes, but it can be cured with proper treatment and an improved lifestyle. Let’s find out in detail what fatty liver is, how it is caused, how it can be treated, and what the stages of fatty liver are.
What is Fatty Liver Disease?
Fatty liver occurs when too much fat collects in the liver, even though the liver should only have a small amount of fat (about 5%).
When fat increases beyond this, the liver may become stressed and not work as well in cleaning toxins, controlling sugar, and helping digestion.
A lot of people don’t even know they have it because the fatty liver disease symptoms can be very mild or show up slowly. It’s becoming more common because many of us live a sedentary lifestyle and eat a lot of processed foods.
The good news is that if it’s caught early, it can be reversed. Regular checkups and simple blood tests can help spot it in time. Keeping a healthy weight, drinking enough water, and staying active all help keep your liver healthy.
Causes of Fatty Liver Disease
The main causes of fatty liver disease are all due to following an improper lifestyle, not exercising, or excessive alcohol consumption. Some of the main fatty liver disease causes are:
-
Eating too many fatty, sugary, or processed foods
-
Being overweight or obese
-
Diabetes or insulin resistance
-
High cholesterol or triglycerides
-
Drinking too much alcohol
-
Lack of regular exercise
-
Certain medications or health conditions
Apart from obesity, poor diet, diabetes, and alcohol, fatty liver disease can also be caused by other factors. Rapid weight loss or certain surgeries, like stomach surgery, can increase fat in the liver.
Genetic factors can make some people more prone to fat buildup. Certain medications, such as steroids or some cancer drugs, may affect the liver. Even viral infections like hepatitis C can contribute.
Fatty Liver Disease Symptoms
In the early stages, fatty liver often doesn’t show any obvious signs. But as the condition develops, some symptoms may appear. Some of the most common fatty liver disease symptoms that are being observed in patients with fatty liver disease are:
-
Feeling tired or weak
-
Mild pain or discomfort in the upper right side of the belly
-
Unexplained weight loss in some cases
-
Swelling in the abdomen or legs (in advanced cases)
-
Liver problems are detected in blood tests even if you feel fine
Fatty liver symptoms in females are very mild at first. Common signs include tiredness, upper right belly discomfort, unexplained weight changes, and sometimes bloating or digestive issues.
For a clear and trustworthy explanation of this condition, you can check the American Liver Foundation’s page on Steatotic (Fatty) Liver Disease, which covers what it is, how it develops, and ways to support liver health.
Stages of Fatty Liver Disease
Fatty liver disease usually develops in four stages, starting mildly and sometimes becoming serious if ignored.
-
Simple Fatty Liver (Steatosis):
-
Fat starts building up in the liver.
-
Usually has no fatty liver disease symptoms and may be found during routine tests.
-
This stage is reversible with a healthy diet and exercise.
-
Non-Alcoholic Steatohepatitis (NASH):
-
Fat buildup causes inflammation in the liver.
-
You may feel tired or have mild pain in the upper right belly.
-
Needs medical attention to prevent worsening.
-
Fibrosis:
-
Continuous inflammation starts causing scar tissue in the liver.
-
The liver still works, but less efficiently.
-
Lifestyle changes and treatment are important to slow down the damage.
-
Cirrhosis:
-
Severe scarring has occurred, and the liver cannot work properly.
-
It can lead to serious complications like liver failure.
-
This stage is not fully reversible, but treatment can manage symptoms.
Fatty Liver Vs Normal Liver
A normal liver is smooth, reddish-brown, and healthy. It has very little fat inside (about 5% of its weight) and works efficiently to clean blood, store energy, and control sugar and cholesterol.
A fatty liver looks larger, paler, and yellowish because of the extra fat stored in liver cells. This fat makes the liver swollen and less effective, slowing down its ability to remove toxins, manage blood sugar, and process nutrients.

When should I see a doctor?
In the beginning, you may not notice any clear signs of fatty liver disease. Many people feel fine, even when fat is building up in the liver. But over time, it can start causing mild symptoms or health problems. That’s why it’s important to know when to see a doctor.
-
You feel tired or weak for no reason
-
You have pain or discomfort in the upper right side of your belly
-
You are overweight or have obesity
-
You have diabetes or high cholesterol
-
You drink alcohol regularly
-
You want to check your liver health early to prevent serious problems
If you experience sudden severe abdominal pain, yellowing of the skin or eyes, or vomiting blood, seek emergency medical care immediately. These can be signs of advanced liver disease.
Treatment and Diagnosis for Fatty Liver
Diagnosis:
Doctors usually start by checking your medical history, lifestyle, and risk factors. Blood tests can show how well your liver is working, and an ultrasound or other imaging tests can detect fat in the liver. In some cases, doctors may recommend FibroScan, a CT scan, or a liver biopsy to see how serious the condition is.
Treatment for Fatty Liver Disease
There is no single medicine for the treatment of fatty liver disease, but it can often be managed and even reversed with lifestyle changes:
-
Healthy diet: Eat more fruits, vegetables, whole grains, and lean protein. Reduce sugary, fried, and processed foods.
-
Regular exercise: At least 30 minutes a day can help reduce liver fat and improve overall health.
-
Weight management: Losing even a small amount of weight can improve liver function.
-
Controlling other conditions: Managing diabetes, high cholesterol, or blood pressure helps reduce liver stress.
-
Avoid alcohol: Especially if your fatty liver is alcohol-related.

Along with medicine, lifestyle changes are the most effective way to treat fatty liver:
-
Eating a healthy, balanced diet
