Why Your Stomach Growls When You Haven't Even Missed a Meal
You are sitting quietly in a meeting when your stomach suddenly produces an enormous rumble. You have eaten recently, you are not particularly hungry and yet your abdomen sounds as though it is announcing lunchtime to the entire room. These noises are usually perfectly normal. They are produced as muscles in the stomach and intestines move food, liquid and gas through the digestive tract. Hunger can make the sounds more noticeable, but it is certainly not the only reason they happen. In fact, your digestive system is active almost all the time, whether or not you are eating.
Those contractions can push around a mixture of food, digestive fluids and gas, creating vibrations and sounds that travel through the abdomen.
Medical literature refers to these noises as borborygmi . They are a normal consequence of gastrointestinal movement.
But digestion itself can also be noisy. Eating does not switch the digestive system into silence.
Swallowed air, certain foods and changes in intestinal movement can all influence the sounds you hear.
Eating quickly can also increase swallowed air, which may contribute to abdominal noises.
Most of the time, there is nothing mysterious or dangerous about a noisy stomach.
For everyday rumbling, though, there is usually no reason to panic.
Your stomach is not necessarily telling you that you need food. It may simply be reminding you that digestion is a noisy, muscular process that never completely switches off.
Your Gut Is Constantly Moving
The digestive tract is not a passive tube. Muscles contract in coordinated waves to move its contents along.Those contractions can push around a mixture of food, digestive fluids and gas, creating vibrations and sounds that travel through the abdomen.

Why Hunger Gets the Blame
Stomach noises often become louder when the stomach is relatively empty. When there is less food present to dampen the movement, sounds from contractions can become easier to hear.But digestion itself can also be noisy. Eating does not switch the digestive system into silence.

Why Some People Have Louder Noises
Everyone's digestive system behaves slightly differently. The amount of gas, the composition of a meal and how quickly food moves through the gut can affect the sounds.Eating quickly can also increase swallowed air, which may contribute to abdominal noises.
Most of the time, there is nothing mysterious or dangerous about a noisy stomach.
When It Is Worth Paying Attention
Stomach sounds by themselves are usually harmless. However, persistent changes accompanied by significant pain, vomiting, diarrhoea, unexplained weight loss or major changes in bowel habits should not simply be dismissed.For everyday rumbling, though, there is usually no reason to panic.
