Why Is My Stomach Making Noises? A Dietitian Explains

Your stomach chooses the quietest meeting, the train carriage or the moment everyone stops talking to produce a noise that sounds far bigger than the organ responsible for it.

If this happens regularly, you may wonder whether the noise means you are hungry, digesting food badly or experiencing an IBS flare. Most stomach noises are a normal result of movement inside the digestive tract. However, the timing of the sounds and the other symptoms happening alongside them can provide useful context.

In this article, I will explain what creates bowel sounds, why they may seem especially loud with IBS and when it is sensible to discuss digestive symptoms with a healthcare professional.

What actually causes stomach noises?

The sounds we casually call “stomach noises” often come from the stomach and intestines. Healthcare professionals may describe them as bowel sounds; the medical term for a noticeable rumbling or gurgling sound is borborygmus.

Your digestive tract is a long muscular tube. Coordinated contractions move food, liquid, digestive secretions and gas through it. As these contents are pushed through different sections and around bends, they can bubble, splash or rumble.

Research in healthy people has shown that gastrointestinal sound intensity changes alongside patterns of gut contraction. This is one reason a noisy gut cannot be interpreted simply as “too much gas” or “poor digestion”.

Why does my stomach growl when I am hungry?

Your digestive system does not become inactive when you stop eating. Between meals, the stomach and small intestine produce a repeating pattern of contractions called the migrating motor complex.

You can think of this as a coordinated movement pattern that helps move residual contents through the upper digestive tract before the next meal. A human study using abdominal microphones and manometry found that gastrointestinal sound intensity changed with the phases of this movement pattern and was highest during its strongest phase.

This helps explain why rumbling is often noticeable when your stomach is empty. Hunger may coincide with the sound, but the noise is produced by movementnot by your stomach “asking” for food.

Why can gut sounds become louder after eating?

Eating changes the pattern of movement in the digestive tract. The gut begins mixing a meal with digestive secretions and moving it forwards. A larger volume of food and fluid, swallowed air, a fizzy drink or a meal that increases gas production may make the resulting sounds easier to hear.

This still does not mean that one particular food is automatically a problem. A single loud episode after lunch is not a reliable food-intolerance test.

If noises consistently occur alongside pain, pronounced bloating, diarrhoea, constipation or urgency, it is more useful to look at the complete pattern. Consider what you ate, the portion, meal timing, bowel habit, stress, sleep and, in people who menstruate, cycle-related changes. One sound in isolation tells us very little.

Are loud stomach noises common with IBS?

People with IBS frequently report gurgling alongside bloating, wind and changes in bowel habit. Several processes may contribute:

• Motility: IBS can involve changes in the speed or pattern of gut movement.

• Gas and fluid: Fermentation and altered handling of intestinal contents can change what is moving through the bowel.

• Visceral sensitivity: Signals from the gut may feel more intense or intrusive.

• Attention and anticipation: After repeated embarrassing or painful episodes, it is understandable to monitor the gut closely, especially in a quiet room or before an important event.

Stress can also influence digestive activity and the way internal sensations are processed. Experimental research has found that psychological stress altered the perceived intensity and unpleasantness of a visceral stimulus more strongly in people with IBS than in healthy controls.

That does not make the experience imaginary. It shows that movement, sensitivity, attention and context can all shape how strongly a gut sensation is experienced.

Does a louder gut mean a worse digestive problem?

Not reliably.

The volume of a bowel sound does not provide a severity score for your gut. A dramatic rumble can occur during ordinary digestion, while important digestive conditions are identified from the wider clinical picture rather than loudness alone.

It is also difficult to diagnose motility by listening casually to the abdomen. Even clinical bowel-sound assessment has limitations.

What can you do if your gut sounds are embarrassing?

You do not need to eliminate every digestive sound; a completely silent digestive tract is not a realistic goal. If the noises are frequent or distressing, these steps can help you gather useful information without becoming trapped in constant symptom monitoring:

1. Look for a repeatable pattern. Note whether the sounds occur when hungry, soon after meals, with diarrhoea or constipation, or during stressful situations.

2. Keep meals reasonably regular. Long, unplanned gaps may make between-meal rumbling more noticeable for some people.

3. Notice sources of swallowed air. Eating very quickly, repeatedly chewing gum or drinking large amounts of fizzy drinks may add more gas to the digestive tract.

4. Review symptoms, not sound alone. Pain, bloating, bowel frequency, stool consistency and urgency are more useful than the volume of one rumble.

5. Avoid cutting out foods on guesswork. If food seems involved, use a structured assessment rather than creating an increasingly restricted diet.

The right strategy depends on your full symptom pattern. Advice for someone with constipation and incomplete emptying may look very different from advice for someone with rapid post-meal diarrhoea.

When should you seek medical advice?

Arrange a GP appointment if digestive symptoms have persisted for more than four weeks or you think you may have IBS but have not been assessed. Tests may sometimes be needed to rule out other causes, including coeliac disease, infection and inflammatory bowel disease.

Loud noises alone are usually less informative than the symptoms occurring with them.

The useful question is not simply “How do I make it quiet?”

A noisy digestive system can be awkward, but treating every gurgle as a warning sign can lead to anxiety, food restriction and more confusion.

A better question is:

What pattern do the sounds belong to?

If they happen without pain or bowel changes, they may simply reflect normal movement. If they sit within a wider pattern of bloating, pain, urgency, constipation or diarrhoea, understanding that pattern gives you a much clearer starting point.
