Why Does Liver Cirrhosis Kill So Quickly. My Brother In

why does liver cirrhosis kill so quickly. my brother in law died recently (dec 3, 2015) after having received the diagnosis 1 year and a half ago. He was a tall, slim man....never drank alchol but would smoke a shisha every night. the doc's never found how he caught the disease and he died due to blood poisioing due to liver failure. everwhere i read it says nothing about shisha (or cigarettes) causing such a disease but is it possible it does. i know that smoking is bad and it kills but can it also create liver cirrohis.
