Your digestive process can be as individual as your personality, and a number of factors depend on how food passes from your mouth to your esophagus, stomach, intestines and outside your body. If you are concerned you may not be digesting food as efficiently, understanding the typical time frame for your digestive process can help. Always speak to your physician if you are concerned you may not be digesting foods properly.
Depending on your individual digestive factors, the entire digestive process from eating food to excreting it via your stool can take between 24 and 72 hours, according to MayoClinic.com. Passing food from your stomach to your small intestine takes about six to eight hours. From there, the stool passes to your bowels, which includes the colon.
