Patients with severe fatty liver, if the condition is serious and there is excessive accumulation of fat in the liver, the liver capsule may be overly distended. This stretching of the liver ligaments can cause pain in the liver area. At this time, patients may feel intense pain or tenderness in the upper right abdomen, and sometimes rebound pain may also occur. When pain in the liver area appears in patients with fatty liver, it indicates that the condition has become very severe and requires active treatment. If the condition progresses further, it can lead to fatty liver, hepatitis, liver cirrhosis, and even severe hepatitis or liver failure, which can greatly affect the patient's quality of life and life expectancy.
