Cirrhosis can be reversible to some degree depending on the severity and persistence of the underlying disease. While uncommon, regression of fibrosis and scarring can occur, especially in early-stage cirrhosis diagnosed on histology. Complete reversal is not seen in clinical or decompensated cirrhosis where vascular changes are established. Historically cirrhosis was considered a single stage disease, but it is now recognized as a series of progressive steps, with the potential for some regression if the cause is treated early enough before irreversible changes develop.
