The treatment of fatty liver includes pharmacotherapy, surgical treatment, and dietary and lifestyle management. Since the occurrence of fatty liver is related to various factors, it is important to adhere to the principles of early detection, early diagnosis, early treatment, and comprehensive management. Active measures should be taken to treat the cause of the disease. For example, it is crucial to quit alcohol early, discontinue medications harmful to the liver, monitor the patient's weight, and actively encourage weight loss. In everyday pharmacotherapy, vitamins, B-complex vitamins, vitamin C, vitamin K, and folic acid can be used. Appropriate hepatoprotective medications can also be utilized. In severe cases, liver transplant surgery or weight loss surgery may be necessary.
