The stomach gurgling sounds, also known as borborygmi, are usually caused by the movement of gas, liquids, and partially digested food through the intestines during digestion. These sounds can be louder or more frequent when the stomach or intestines are empty because there is less content to muffle the noise. Additionally, swallowing air (from eating too quickly, chewing gum, or drinking through straws), certain food intolerances (like lactose or fructose intolerance), diet factors (such as high-fiber foods or artificial sweeteners), and gastrointestinal conditions (like irritable bowel syndrome) can increase the frequency and volume of these gurgling noises. Stress and bacterial overgrowth in the gut can also contribute to increased stomach noises. If accompanied by other symptoms like pain, bloating, diarrhea, or constipation, it might indicate an underlying digestive issue. However, occasional stomach gurgling is usually normal and is part of the digestive process.
