The most serious consequence of polycystic liver is that it affects liver function, induces liver failure and eventually requires liver transplantation. If polycystic liver is not treated in time, and the disease develops to the advanced stage, it will have a greater impact on the liver function, and it will hurt the liver cells, and this kind of patients is very easy to cause liver failure, and ultimately, it may need to remove the polycystic liver through liver transplantation and transplant a normal liver, which is able to maintain the normal metabolism of the liver. It is worth mentioning that polycystic liver may also be accompanied by conditions such as polycystic kidney, which may be accompanied by conditions such as renal failure. At present, most polycystic livers are not serious and can be controlled by regular treatment, but it is necessary to go to the hospital regularly for review and targeted treatment under the guidance of physicians.
