Stomach growling, also known as borborygmi, happens when the stomach and intestines contract to move food, fluids, and gas through the digestive tract. This muscular action, called peristalsis, produces rumbling sounds, especially when the stomach is empty or during digestion. The growling can be caused by hunger, as the stomach releases the hormone ghrelin signaling it's time to eat, or by the normal digestive process of moving gas and partially digested food along. It can also happen due to swallowed air, certain foods that cause gas, or digestive conditions. Sometimes, stomach growling can signal underlying issues if accompanied by other symptoms like pain or digestive distress.
Key Causes of Stomach Growling
- Hunger: The body releases ghrelin causing stomach and intestinal contractions that create growling sounds.
- Digestion: Movement of food, gas, and fluids through the stomach and intestines during digestion creates noise.
- Gas: Excess gas from food fermentation or swallowed air can increase stomach noises.
- Certain foods: Foods like beans, cabbage, broccoli, and dairy (especially if lactose intolerant) can cause more gas and growling.
- Stress and anxiety can also affect stomach noise due to changes in digestive function.
Additional Notes
While stomach growling is generally normal, it can sometimes indicate gastrointestinal problems such as infections, food intolerances, or bowel obstruction when associated with other symptoms.
