Epistaxis for 10 points?

Question

how can hepatis sirosis, heart failure can make sombody epistaxis

Answer 1

The portal hypertension rises causing oesophageal and even nasal varicies, which may leak or burst and cause epistaxis.

In other words, when the liver is damaged the blood pressure in the liver circulation gets higher.  This causes higher pressures in the weaker blood vessels of the oesophagus, throat and nasal pasages.  If these varicosed blood vessels leak or burst, they will bleed - sometimes fatally.
