Fatty liver does not necessarily cause a large belly. Fatty liver is the result of excessive accumulation of fat in the liver. Fatty liver is often accompanied by physical obesity, but it can be mild or severe. Mild cases of fatty liver do not require treatment, but only diet and exercise. In moderate to severe fatty liver, there will be obesity and fat accumulation in the abdomen, which will lead to abdominal distension, that is, large stomach, and if it causes abnormal liver function, medication will be needed. In addition, there are some patients who are very thin, but also have fatty liver, mainly due to abnormal lipid metabolism. Therefore, fatty liver does not necessarily cause a large stomach, but is affected by two factors: the severity of the fatty liver and the metabolism of lipids.
