Sorry for your lost. Sorry for your lost. I am afraid nobody here at the healthtap will be able to answer your question for sure. You should be able to get the answer of your question from all doctors who were involved in the care of your mother in regard to the cause of death etc. I don't know how close you're with your mom- some moms didn't want to tell their kids bad things happened to them to protect her kids.
