My best friend is Passing out from her heart, and also swelling in her ankles that is coming from her heart and also and her heart rate goes between 120 beats per minute , down to as low as 60 beats ...
Dilate a bit - but depends on what you are refering to as natural causes.
it does not matter how they died. there eyes will always dialate.
When breathing and the heartbeat have stopped, the eyes become fixed in position and the pupils dilate.
good Question the Eyes Dilated and Fixed
AC has the answer that I was going to say, they always dilate when you die
All the above respondents answered very well, but they forgot to mention DILATED AND FIXED. If you don't write FIXED in the death certificate you can land in trouble.
Hope it's clear to all, always be cautious in written works.
