Fatty liver is divided into alcoholic and non-alcoholic, and its disease progression is as follows: simple fatty liver, steatohepatitis, liver fibrosis, and cirrhosis. Cirrhosis is a lesion characterized by decreased liver function, diffuse fibrosis of the liver, and pseudolobular tissue formation. The etiology includes several aspects, including hepatitis virus, alcohol, autoimmune liver disease, vascular disease, metabolic disease, etc. Fatty liver can also lead to cirrhosis. Fatty liver is a pathological syndrome characterized by excessive fat storage in hepatocytes and fatty degeneration of hepatocytes, mainly including simple fatty liver and steatohepatitis liver fibrosis, cirrhosis, which is a relatively mild and reversible liver lesion, and in severe cases develop into cirrhosis. However, it is important to note that fatty liver, like cirrhosis, is a pathological result and the causes of fatty liver vary in prognosis. If the fatty liver is only caused by fat accumulation, it can usually recover on its own after adjusting the diet, but steatohepatitis requires a clear cause, because steatohepatitis is a generalized pathology, and some factors, such as long-term heavy alcohol consumption, initially start with steatohepatitis, but such factors have a certain chance of developing into cirrhosis. Therefore, although the chances of fatty liver developing into cirrhosis are small, you need to stay alert and have regular medical checkups for early detection.
