Quoting loser mom:" Ohh, I understand. Well, I hope you're able to find something out. What did your mother tell you, if you don't mind saying?"
It sounded like some kind of issue in the small intestine. About 10 months before he died he spent a month in the hospital with severe ulcers in his stomach and small intestine. There was one in his small intestine that was so large it required surgery. As far as I know, after he was discharged from the hospital, he refused to go back to the doctor.
In late March or early April he started having stomach pains again. My mom made appointment after appointment, and he constantly blew them off. These where specialist appointments, too. Not easy or fast to get. Finally, he agreed to see a doctor, but he was gone before he could get back in. He was feeling better on Friday, felt sick Friday night, and died Saturday early morning. My mom and I think it was related to that issue 10 months before.
Sorry for the slow replies. My two year old helper isn't so helpful. Lol.
