Fatty liver is relatively common in clinical practice. It is not an infectious disease and is not contagious. Fatty liver is generally considered to be caused by various reasons leading to fat deposition in the liver. Usually, there are no specific symptoms. Some patients may experience pain, dull pain, or discomfort in the upper right abdomen, along with nausea, etc. Typically, patients discover they have fatty liver during a physical examination or incidental liver function tests and abdominal ultrasound that indicate changes due to fatty liver. The general principle of treatment is symptomatic management. If liver function is abnormal, hepatoprotective treatment can be considered. Of course, if liver function is normal and it's purely fatty liver, the main approach is adjusting dietary and lifestyle habits. It is advised that patients consume high-quality proteins and reduce intake of greasy, fatty, low-fat, and low-sugar foods. Maintaining a good mental state, appropriately reducing weight, and exercising can cure mild fatty liver. If there is severe fatty liver, it is recommended that patients visit a local hospital for treatment.
