Fatty liver disease is extremely common, yet many people do not know they have it. In its early stages, the condition often causes few or no obvious symptoms. It develops when too much fat collects inside liver cells.
The liver performs hundreds of important jobs, including processing nutrients, removing harmful substances from the blood and helping the body digest food. A small amount of fat in the liver is normal, but excessive buildup can cause inflammation and damage over time. In some people, this damage eventually leads to serious liver disease.
There are two broad causes of fatty liver. One is related to heavy alcohol use, while the other occurs in people whose liver fat is mainly connected with metabolic problems such as obesity, type 2 diabetes and abnormal blood fats.
The latter condition is now commonly called metabolic dysfunction-associated steatotic liver disease, or MASLD, and was previously known as non-alcoholic fatty liver disease.
Because early fatty liver disease is often silent, people sometimes look for visible clues. Certain changes around the face and eyes can occur in people with advanced liver problems. However, these signs are not specific to fatty liver disease and cannot be used to diagnose it.
One of the best-known visible signs of serious liver trouble is jaundice. This causes the skin and the whites of the eyes to turn yellow. It happens when bilirubin, a yellow substance produced as old red blood cells are broken down, builds up because the body cannot process or remove it normally.
Jaundice is more likely to appear when liver disease has become significant rather than during the early stages of simple fatty liver. It can also have other causes, including problems with the gallbladder, bile ducts, pancreas or blood. Anyone who develops new yellowing of the eyes or skin should seek medical assessment.
Another possible sign is the appearance of small blood vessels called spider angiomas. They have a red central point with thin vessels spreading outward, giving them a spider-like appearance. They can occur on the face, neck, upper chest and arms.
A few spider angiomas are not necessarily a sign of disease. They can occur in healthy people and during pregnancy, but larger numbers may be seen in people with chronic liver disease. Doctors therefore consider them alongside other symptoms, medical history and test results.
Swelling around the eyes or face is sometimes blamed on liver problems, but this symptom has many possible explanations. Allergies, lack of sleep, kidney disease, thyroid problems and fluid retention can all cause puffiness. Advanced liver disease can disturb the body’s control of fluid, although facial swelling alone does not point specifically to fatty liver.
Changes in skin color can also have many causes. People with chronic liver disease may sometimes develop unusual pigmentation or paleness, but these changes are not reliable early warning signs of fatty liver. Skin appearance can be influenced by sun exposure, anemia, hormones, medicines and many other conditions.
The important point is that most people with early fatty liver disease will not be able to see it by looking in a mirror. Doctors usually identify the condition through a person’s medical history, blood tests and imaging such as ultrasound. Additional tests may be needed to determine whether the liver has developed inflammation or scarring.
Without proper management, fatty liver disease can progress in some people from simple fat buildup to inflammation and fibrosis, which means scarring of the liver. Severe scarring is called cirrhosis and can eventually lead to liver failure or liver cancer. Fortunately, progression is not inevitable, and early changes can often be improved.
Maintaining a healthy weight, exercising regularly and eating a balanced diet can reduce liver fat and improve metabolic health. Limiting alcohol is also important because alcohol can add further stress to an already unhealthy liver. People with diabetes, high blood pressure or abnormal cholesterol should work with healthcare professionals to keep these conditions well controlled.
Facial changes such as jaundice or numerous spider-like blood vessels should be taken seriously, but they should not be treated as a home test for fatty liver disease.
People who are concerned about their liver, particularly those with metabolic risk factors or heavy alcohol use, should speak with a healthcare professional. Proper testing is far more reliable than trying to diagnose liver disease from appearance alone.
If you care about liver health, please read studies about a diet that can treat fatty liver disease and obesity, and coffee drinkers may halve their risk of liver cancer.
For more health information, please see recent studies that anti-inflammatory diet could help prevent fatty liver disease, and results showing vitamin D could help prevent non-alcoholic fatty liver disease.
