How long does it really take for the food to digest in your stomach?

I'll be donating plasma in the morning and I need to know

Report as

I don't know, I'm still worried about all the gum I swallowed in grade, middle, and high school. (I was told gum takes 20 years to digest--Bazooka brand a little longer, Wrigleys a little less.)

20 years! Pretty sure someone was messing with you. The gum shoud be digested in 48 hours.

Correction to my earlier post.
The gum should pass through your system in 48 hours. It is not fully digested. You should not eat gum. See this link for more info http://www.scientificamerican.com/article.cfm?id=fact-or-fiction-chewing-gum-takes-seven-years-to-digest

Depends first off how much you ate! I was told growing up it was half-hour but imagine it's got to be longer than that. I've eat things and then an hour-and-a-half later have thrown them up...that food had still been in my stomach obviously. Usually when you have blood drawn in the morning you can't have eaten until the night before (I.e. 8-12 hrs).

But you're not telling me exactly how long it will take

They usually say 8-10 hours to be on the safe side; but I would guess it's shorter than that, maybe 5-6 hours?? Obviously if you've eaten a steak dinner vs. eaten a yogurt that will make a difference in time to digest

I believe you have already donated the plasma.
I have only heard about people donate blood that is then separated to its various components and given to needy patients.

The only circumstances under which plasma only removed is when it is harmful to you and so others. It is a form of treatment. I hope you are better and the recipient is safe:)

Just your stomach, I don't know. I DID learn in science class that from the time you eat a piece of food until the time it ejects out your rear end is 48 hours.

Good answer.

What about your stomach not his/hers:)

The gum you swallowed in the past is most likely all gone. Stomach acid is strong stuff. And the body gets rid of anything it can't digest if it can pass the digestive tract.

The total time for something that goes in the mouth to pass through the entire digestive track will vary between 12-24 hours.

Your Para II isn't about digestion is it? :)

Anything that goes in your mouth that is a solid, goes into the stomach, and then into the digestive tract. Nutrients are extracted throughout most of the digestive tract, and only waste solids are excreted at the end.

So it's about transit time of unabsorbed waste not time of digestion in the stomach only which I guess is the question:)

it takes at least a day to be dissolved and digested so yeah that only stands for solid food. that is why a baby can't eat solid food because its digestive system isn't fully grown.

I'll only tell you why it is difficult to answer your question.
1; For a human biology student; Very little digestion takes place in the stomach. In the stomach, food is made fluid for prober digestion to occur in the small intestine. The little digested protein in the stomach will be finally and finely digested in the small intestine for absorption.

2; For non-human biology student I guess the question means the entire process of digestion to the point of complete absorption and stomach means abdomen. So it depends on the type and form of food one eats. Presumably minimum of 4 hours and maximum of 12 hours but I need to be corrected.

It depends on the food. Certain foods are digested easily (the ones they give you in the hospital after a surgery let's say) and others take more time. Certain foods with lots of fiber don't get completely digested but we still need them. How well you chew your food will affect how long digestion takes. Women take longer to digest food than men.

Fruits take around 4 hours to exit the stomach.
Vegetables 5 hours
Meats 8 hours
Cheese takes 10 hours.

Thorough chewing will prepare food so that your body is able to extract more nutrition from your food. If you eat fruits and cheese together, your fruits will be in your stomach 6 hours more than they should have been, and they will ferment.

If doctor removes the stomach, will food be digested?
Report as
No the food won't be digested, the food will simply build up in your body until either your body cavity explodes or you become sick due to the toxins being released by the bacteria and maggots that are trying to digest the food for themselves, although much more inefficiently than a stomach.

It depends on the food content, look on the ingredients and try to research itto the computer, remember internet is a free research material. :)

Umm depends on how much the person eats so it's like a directly proportional to the amount eaten . like the more ate the more time taken. From what I read it's about 24 hours I think

Digestion time varies between individuals and between men and women. After you eat, it takes about six to eight hours for food to pass through your stomach and small intestine. Food then enters your large intestine (colon) for further digestion, absorption of water and, finally, elimination of undigested food.

In the 1980s, Mayo Clinic researchers measured digestion time in 21 healthy people. Total transit time, from eating to elimination in stool, averaged 53 hours (although that figure is a little overstated, because the markers used by the researchers passed more slowly through the stomach than actual food). The average transit time through just the large intestine (colon) was 40 hours, with significant difference between men and women: 33 hours for men, 47 hours for women.

http://www.mayoclinic.com/health/digestive-system/an00896 - is where I found the information, you can read more about how it works!

Eat some fresh corn and watch for it in your stools. Fruit usually takes 2 hours if eaten alone. Protein takes 4 hours, also alone. If fruit has to wait for other foods
it spoils. Recommended reading: Mary Ann Shearer's The Natural Way sold by Focus on the Family. Dr David Williams writes Alternatives newsletters. Fit for Life is another helpful book.

The answer to the question should be less than 48 hours depending on what was eaten.

Got to go in for a colon scan this week. Mon - Tue on a strict no fibre diet. Wed can have only liquid such as beef bullion then get to drink a gallon of liquid designed to clean out the entire digestive tract. Since this works, then everything will have been digested and gone in 48 hours.
