Dear friend, welcome to Healthcaremagic!
I am Dr. Prasad Akole (Critical Care Expert- http://bit.ly/Dr-Prasad-Akole) and am glad to address to your query here.
It is quite possible to have a massive hematemesis
of blood) and die of massive haemorrhagic shock or asphyxiation from blood flooding the throat.
and pain medications make it very likely to have stomach ulcers/ gastritis
from alcoholic liver diseases.
There are many other possibilities of course, which can not be evaluated from here. Please await autopsy reports.
I hope to have answered your query satisfactorily. I would be glad to answer any further queries. Take care and please keep me informed of your progress at http://bit.ly/Dr-Prasad-Akole
