How long does it take for food to leave the stomach?

[emmma]

Hey,

I was wondering if anyone knows how long it takes for food to pass through the stomach before it moves out of the stomach into the small intestine?

I love scientific questions... x

In the stomach, food tends to hang around in the stomach for different time scales depending on a variety of factors including the amount of food you have consumed, how much fat it contains, and also the acidity of the stomach. However, all food should have left the stomach within 2 to 4 hours.

(approx. time spent in stomach before emptying)

Liquid:

Water - when stomach is empty, leaves immediately and goes into intestines,
Juices - Fruit vegetables, vegetable broth - 15 to 20 minutes.

Thanks for your informative reply

That's really interesting, Chew!

However, many people who have purged for a long time experience gastroparesis (delayed stomach emptying). This varies widely from person to person.

I agree, I might suffer from that myself. x

Hmmm, that's pretty interesting, and I guess it would explain a few things - I never thought things could stay in your stomach up to 4-5 hours!
The only thing that remains a mystery is carrots - I think they take about 12 hours to leave my stomach. I can purge them the day after and they're still in a perfect round flat slice shape... It always makes me think 'Wtf, did I just not bother to chew that meal at all?'

Some people lack digestive enzymes, this means carrots might not agree with you & you could be allergic to them, A good way to know whether this is the case is some people with an allergy to a food can obsession over eating it, loving carrots to the point of no return would be something that may be a clue, Although...

I often purge left over spinach curd and carrots hours after eating them, I can't recall it taking 12 hours though. x
