@doctorsood: How often do you catch your stomach making noise? Those rumbling sounds you hear, known as borborygmi, come from gas and fluid moving through the intestines during normal peristalsis. Stress and hunger hormones can amplify them, but in most cases these sounds are a completely normal sign of an active digestive system.
