Obesity-related conditions
Fatty liver: symptoms and diagnosis
Fatty liver often causes no symptoms. Fatigue or abdominal pain alone cannot establish the diagnosis; tests and assessment of liver damage risk matter more.

Why might there be no symptoms?
Fat can accumulate in the liver for a long time without obvious signs. Lack of pain or a normal appearance does not rule it out. Abdominal obesity, type 2 diabetes, abnormal blood lipids and other metabolic conditions increase the risk, although people without obesity can also be affected.
Fatigue and right-sided abdominal discomfort
Some people experience fatigue or discomfort in the upper right abdomen. These symptoms are not specific and have many other causes. Jaundice, swelling of the abdomen or legs, and confusion are not typical early symptoms of fatty liver; they may indicate advanced disease or another problem.
How is it diagnosed?
Your doctor reviews your medical history, alcohol intake, medicines and supplements. Blood tests and imaging such as ultrasound may be used to assess liver fat. Standard ultrasound alone cannot determine the severity of inflammation or scarring. When needed, scores such as FIB-4, elastography and sometimes a biopsy help assess fibrosis.
Which signs need prompt attention?
Yellow eyes or skin, increasing abdominal swelling, vomiting blood or black stools require prompt medical assessment. New confusion, unusual drowsiness or severe gastrointestinal bleeding are emergencies. Do not rely on home remedies, herbal drinks or self-prescribed diuretics for these symptoms.
What should you ask at your appointment?
Bring test results and a medication list. Ask about fibrosis risk, whether you need a liver specialist and how often to follow up. Weight management and treatment of metabolic conditions are part of care; there is no single prescription for everyone.
