Abdominal pain associated with fatty liver disease often occurs in the center or upper right part of the stomach, according to WebMD. Nausea and loss of appetite are additional symptoms of fatty liver disease.
Other symptoms that are associated with non-alcoholic fatty liver disease are fatigue, weight loss, weakness, confusion and poor judgment, or problems with concentrating. The skin on the neck and under the arms may develop dark patches, adds WebMD. However, in most cases of fatty liver disease, symptoms do not occur right away and often take decades to develop. These symptoms are also connected with alcoholic fatty liver disease. In alcoholic liver disease cases, symptoms may become worse after drinking heavily.
Specific causes of fatty liver disease are unknown, as of 2015. However, contributing factors include being overweight or obese, genetics, high cholesterol, certain medications, malnutrition and autoimmune diseases. Viral hepatitis and rapid weight loss are other contributing factors, according to WebMD.
Methods for improving or managing this condition include quitting drinking, gradual weight loss, regular exercise, and adopting a healthy and well balanced diet. WebMD recommends limiting the intake of foods that are high in carbohydrates such as bread, grains, potatoes and rice. Cutting out sugary drinks also helps.
