Peristalsis, or stomach gurgling is the sound of smooth muscles contracting and pushing your food down your small bowel and into your colon. The digestive tract processes food, drink, and air; gurgling is a result of this interaction. It is often a natural occurrence. But, if you’re constantly feeling stomach gurgles, along with other symptoms like pain, diarrhea, constipation, excess gas, or foul-smelling stool, it might mean it’s time to see a doctor.
