Hi thanks for asking question. As you have portal hypertension it doesn t mean you will die early.. Life expectancy depend on many factors like episodes of variceal bleeding, hepatic vein pressure , life style care you are taking etc... Patient have very bad prognosis and die within 1 year only if hepatic vein pressure above 20 and more then one episode of variceal bleed.Other wise 5 to 10 year survival can be there. To reduce death rate treat portal hypertension by beta blocker ..And trans jugular intra hepatic shunt can be put for lowering portal hypertension. For ascites take diuretic and low salt diet. Death in portal hypertension mainly due to variceal bleeding so whenever you have blood in vomit immediately consult surgeon for endoscopic treatment. Cutt off oil in diet. I hope your concern solved. Take care...
