That sudden growling from your stomach during a meeting, classroom or quiet room can be embarrassing when everyone seems to hear it. But it’s a normal part of digestion. Contrary to popular belief, a growling stomach does not mean that the body is starving you; it doesn’t even mean your body is hungry at all.
The sounds are part of the digestive system’s natural activity and can happen even when you are not hungry, according to Dr Anukalp Prakash, Director of Gastroenterology at CK Birla Hospital, Gurugram.
What causes your stomach to growl?
The medical term for these sounds is “borborygmi”. They are produced when muscles in the gastrointestinal tract contract and move fluids, food particles and gas through the digestive system.

Dr Anukalp explains that one reason behind these sounds is the migrating motor complex (MMC). This is a series of muscular contractions that move through the stomach and small intestine between meals, usually in cycles of about 90 minutes to two hours.
It is basically a housekeeping system. It helps to pass the food particles, secretions, bacteria, and even gas through the digestive system.
When the stomach is filled with food, this movement is muffled. When it’s relatively empty, however, there is less material to absorb the sound. As a result, the movement of air and fluids can be much more noticeable.

Why does stomach growling feel connected to hunger?
Stomach noises are often more noticeable when you have not eaten for several hours. And so that is why people associate growling with hunger.
However, the sound itself is not a direct measure of hunger. The digestive tract can continue to make these sounds—regardless of whether or not you are hungry.
As a matter of fact, your stomach may growl after eating, drinking water, or during digestion. Nervousness and stress can also impact gut movement, so digestive sounds can be more prominent in some of those situations.
Does a quiet stomach mean poor digestion?
Not at all. Another common misconception is that a silent stomach indicates that digestion is not working properly.
Digestive sounds naturally vary throughout the day. A fuller stomach may muffle movement, while changes in food intake, fluids and intestinal activity can alter how audible these sounds are.
So there is no need to worry just because your stomach is unusually quiet—or because it suddenly makes a loud noise.
When should you see a doctor?
Occasional stomach growling is generally harmless. However, it may deserve medical attention when it occurs alongside other persistent symptoms.
I would talk to a doctor if unusual or excessive abdominal sounds are accompanied by persistent bloating, abdominal pain, significant changes in bowel habits or unexplained weight loss. These signs may indicate digestive problems that should be evaluated.
A growling stomach is usually less of an alarm and more of a reminder that your digestive system is always working. Whether you have eaten recently or not, your digestive system is always moving fluids, gases and other contents through your gut.
Hence, the next time your stomach growls in a silent room, there is no need to feel embarrassed. In most cases, it is simply your digestive system doing its everyday job.
