How long does it take to digest food â from the time you eat it to the time you excrete it? Answers from Michael F. Picco, M.D. 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.
How long it takes to digest food In general, food takes 24 to 72 hours to move through your digestive tract. The exact time depends on the amounts and types of foods youâve eaten. The rate is also based on factors like your gender, metabolism, and whether you have any digestive issues that could slow down or speed up the process.
