If you have fatty liver disease, the symptoms are essentially the same as those of chronic hepatitis B and C, which include nausea, vomiting, loss of appetite, aversion to oily foods, and fatigue. Additionally, patients with fatty liver disease may experience a sensation of swelling and pain in the liver area. At this point, further liver function tests such as measuring transaminase and bilirubin levels can be conducted, and performing a hepatobiliary ultrasound can definitively diagnose the condition. If the fatty liver is due to obesity, it is advisable to strictly control food intake and engage in active and reasonable exercise for weight loss, as fatty liver can be reversed. However, if the fatty liver is due to long-term excessive alcohol consumption, it is recommended to strictly quit smoking and drinking, combined with reasonable exercise and diet control, as fatty liver can also be reversed.
