lots of unknowns... was she on dialysis to begin with.. did she decide to just stop getting dialysis on her trip.. did her kidney function decline in hungary... how much weight did she gain.. was she compliant with her medicines etc
and what caused her death? blood clot? heart attack? electrolyte disturbance?
sounds like she had lethal chronic disease to me and was unable to be transported safely...who's to say she wouldnt have dropped dead on the plane over the Atlantic, or in her own bed in her own house.
One must wonder how she was txported to Hungary in the first place????
