There is a good discussion on cirrhosis, which includes an in depth section on the complications from cirrhosis at: http://www.medicinenet.com/cirrhosis/article.htm. The article also discusses the various treatments available for these inevitable complications. Having suffered from cirrhosis myself, this requires immediate and continuing medical treatment as the disease progresses. I was fortunate enough to qualify for a liver transplant, which in the end stage of cirrhosis is the only solution.
