Bowel transit time, the time it takes for food to travel through the digestive tract, depends on what types of food you eat and how much you drink. It also varies between individuals and between men and women.
As explained by the WebMD, after you chew and swallow your food, it moves into your stomach, where it is mixed with acid and digestive enzymes. After your food leaves your stomach, it is squeezed through your small intestine, where nutrients are absorbed for use by your body. The food then goes into your large intestine (colon) where water is absorbed. Whatever hasn't been digested and absorbed by your intestines combines with bacteria and other waste products and becomes stool (feces).
A research conducted by Mayo Clinic in 21 healthy people showed that total transit time, from eating to elimination in stool, averaged 53 hours. 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.
