In a normal person: without any prior surgeries or GI diseases, about 60 90 minutes from the mouth thru the small intestine to reach the colon and then another 24-36 hours thru the colon or large intestine to the anus. Of course food that cause diarrhea or constipation can change this in either direction

Variable: Amount of time between eating food and processing entirely to defecation varies between people a lot. It takes 6-8 hours for food to through stomach and small intestine. From there it goes to large intestine for more digestion, absorption of water, and then elimination of waste. Studies have shown between 33 - 53 hours total. Kids might be faster than adults -- and medications can affect it too.

What you eat will also change the speed at which you processed food too!

What are the parts of the digestive system tbrough which food passes?

Dr. Jason Boardman
General Surgery 25 years experience
Parts of GI system: The GI system start with the mouth and teeth. This is where digestion begins. The food is the swallowed and taken to the stomach via the esophagus. In the stomach food is exposed to acid and mechanical grinding. Food then passes into the duodenum, jejunum and ileum where nutrients are absorbed. The liquid then enters the colon where water is absorbed and then out through the anus.

Peristalsis: Rhythmic wavelike squeezing and relaxiation from the mouth to the anus
Dr. Susan Rhoads

Dr. Hammerstead is correct. And the noise your stomach and intestines make as the peristaltic waves push the food through the gut, "stomach growling," has a great name, too, borborygmi! (One growl would be borborygmus. It's a Greek word, and it sounds like what it means, as you see.
