It's been a while since your last meal and your stomach is growling already. Stomach noises like gurgling and growling are most often a harmless part of the digestion process and alert you to the fact that you may be hungry. It can also be potentially mortifying if you are in a quiet room full of people when your stomach starts to talk back. Prevent embarrassing situations by eating a small snack such as a handful of crackers or a granola bar if you do not have time for a full meal. Avoid anything heavy or greasy foods like pizza or potato chips that are likely to produce gas, or your stomach may begin to gurgle even more.
