After a meal, it normally takes 1 1/2 to two hours for food to move out of the stomach and into the small intestine. When your stomach takes longer than normal to empty, it's called gastroparesis.
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. It takes about 36 hours for food to move through the entire colon.
The F.D.A. defines an empty stomach as “one hour before eating, or two hours after eating.” The F.D.A.'s two-hour rule is just a rule of thumb; the stomach will probably not be completely empty. The specific definition of an empty stomach varies from drug to drug.

A damaged vagus nerve can't send signals normally to your stomach muscles. This may cause food to remain in your stomach longer, rather than move into your small intestine to be digested. The vagus nerve and its branches can be damaged by diseases, such as diabetes, or by surgery to the stomach or small intestine.

The average person will take about 10 minutes or less for their body to process one glass of water because they have normal levels of bodily functions such as digestion and absorption.

Common causes of fecal incontinence include diarrhea, constipation, and muscle or nerve damage. The muscle or nerve damage may be associated with aging or with giving birth. Whatever the cause, fecal incontinence can be difficult to discuss. But don't shy away from talking to your doctor about this common problem.
