Steatotic Liver Disease – What It Means and What You Can Do
Steatotic liver disease (sometimes called fatty liver disease) means that there is more fat than normal stored in the liver. It is completely normal for the liver to contain a small amount of fat, since the liver plays a central role in processing the body’s nutrients. However, in some people, too much fat builds up in the liver.
There are several reasons why this can happen, but the two most common are obesity and high alcohol consumption. As obesity has become more common, steatotic liver disease has also increased. When the condition is related to obesity and metabolic health, it is called Metabolic dysfunction-associated steatotic liver disease (MASLD). MASLD is common and can affect both children and adults.
Most people do not notice that they have steatotic liver disease because it often causes no symptoms. However, if it is not detected and managed, a small number of people may develop more serious liver problems over time.
Why Does Steatotic Liver Disease Develop?
The condition most often develops as a result of overweight or obesity. People with steatotic liver disease often have, or are at risk of developing, type 2 diabetes, high blood pressure, and high cholesterol. Even moderate alcohol intake can increase the amount of fat stored in the liver.
If a person has both obesity and drinks alcohol, the risk becomes greater. This is called an interaction between the two factors.
Is It Dangerous?
For most people, steatotic liver disease progresses very slowly and will not cause serious liver damage during their lifetime. However, for a small minority (around 3%), scarring can develop over 20–30 years, leading to severe liver disease (cirrhosis). Cirrhosis carries a risk of serious complications and, in some cases, liver cancer.
In both children and adults, steatotic liver disease also increases the risk of developing type 2 diabetes.
How Do I Know If I Have It?
About three out of four people with obesity have steatotic liver disease. Because of this, it is not always necessary to test for the condition itself. Instead, healthcare professionals focus on checking whether liver damage has developed.
This is done with blood tests and sometimes imaging, such as an ultrasound. If needed, further tests can be carried out to determine whether liver damage is present. In advanced stages (cirrhosis), more specific symptoms may appear.
How Is It Treated?
Currently, there is no established medical treatment for steatotic liver disease or its complications in the Nordic countries. However, new medicines are being developed, and one was approved in the USA in April 2025.
For now, treatment focuses on addressing the underlying causes:
- If obesity is the cause, getting help to achieve a healthier body weight is important.
- Physical activity can reduce fat in the liver — even without weight loss.
- If you have type 2 diabetes, good blood sugar control helps protect the liver.
- Limiting alcohol intake is also essential, and people with liver damage should avoid alcohol completely.
Can It Go Away?
Yes! Steatotic liver disease is often reversible. With lifestyle changes, such as improved diet, physical activity, and reduced alcohol consumption, the liver can recover, and the excess fat can disappear.
The most important factor for predicting long-term outcomes is to assess the degree of liver damage early and take action in time.
