Some medicines need to be taken before food or on an empty stomach. This is because food and some drinks can affect the way these medicines work. For example, taking some medicines at the same time as eating may prevent your stomach and intestines absorbing the medicine, making it less effective.

For some medicines, having food or liquids in your stomach can result in poorer absorption of the drug or an upset stomach. It generally takes 4 to 5 hours for the stomach to empty after a full meal and a bit less after a snack or liquid, though it varies depending on how much and what kind of food you ate. If you can, it’s easiest to take empty stomach medications in the morning, after you’ve fasted overnight. After taking the drug, wait at least 30 minute before ingesting anything other than plain water, to give the body time to absorb the medication.

Gastroparesis is a condition in which your stomach cannot empty itself of food in a normal fashion. It can be caused by damage to the vagus nerve, which regulates the digestive system. A damaged vagus nerve prevents the muscles in the stomach and intestine from functioning, preventing food from moving through the digestive system properly.

As a general rule, medicines that are supposed to be taken on an empty stomach should be taken about an hour before a meal, or two hours after a meal. Forgetting these instructions on rare occasions is unlikely to do any harm, but taking these medicines with food regularly may mean they don't work. Further information:

Some of the complications of gastroparesis include: 1  Food that stays in the stomach too long can ferment, which can lead to the growth of bacteria. 2  Food in the stomach can harden into a solid collection, called a bezoar. Bezoars can cause obstructions in the stomach that keep food from passing into the small intestine.

Food can be 3-4 hours in the stomach, then about 3 more hours as it moves through the intestine. It can stay in the the large intestine for up to 36 hours. So, depending on the type of food and the speed at which it moves, it can take about 40 hours or more. Source(s): http://www.kidcyber.com.au/topics/bodydi...
