Sorry you guys have to deal with that. I have gastroparesis. At my gastric emptying test, most of the food was still in my stomach after 4 hours, at which point I was considered "failed" and sent home
I was told it should have taken about 2 hours, but that up to 4 hours for the amount of food I'd eaten (two pieces of toast and some scrambled eggs) would still put me in the normal range and not give me the diagnosis of gastroparesis, which is what we were suspecting. So I think a pineapple snack should have moved into the small intestine within 30 to 90 min. Not sure how much she ate, but her stomach was empty.
