Eli5: why surgery fasting time is the same for everyone

200 views

This one is inspired by a post I just saw about why you need to fast (puking, stomach acids in lungs, etc)
But here’s the thing. I have indigestion. I swear I’ve puked up DAYS old food before. If I fast 6/12/24 hours and the food is still there isn’t that still the same risk?
I’ve had lots of surgeries with no problems but.. I feel like this is a problem?

The average person’s stomach is empty in 4-6 hours. It’s not necessary to require more than 8-12 hours. Plus, it’s not a good idea for for some people, like diabetics, to go long stretches without eating.
