Hi, this is going to a little hard to describe as my grandfather passed away but he lived in a third world country which I am not currently living in (Cambodia). I live in America. To the best of our knowledge, he was never sick with no chronic condition - his wife is actually the one with memory loss and needs a caregiver. But I was told he had fallen ill a few days ago, was bleeding through his nose and mouth then passed away last night in the hospital. It would be hard to uncover the true cause of death in a third world country like Cambodia and so I'm just wondering what might've happened - was it really some illness or serious flu? I was leaning towards a cancer he probably was not aware of that finally escalated to the point of death but obviously I'm no DR..
