Hi I can understand your concern.... Noted he is having late stage cirrhosis. So ultimate treatment is liver transplantation .... Other new option with less documentation is stem cell therapy.....Stem cell can regenerate liver tissue as having pluripotency .... Meanwhile for ascites prevention take low salt diet.... Diuretic if needed can given.... If you have splenomegaly and features suggestive portal hypertension beta blocker can be given..... Take spinach and carrot juice... Fruits more.... Less invasive procedure like TIPSS like shut placement can done to reduce pressure... Take care..... Dr.Parth Goswami
