You're sitting in a quiet room when suddenly your stomach makes a loud growling noise.
Perhaps it happens when you're hungry. But sometimes your stomach seems to gurgle after eating—or even when you don't feel hungry at all.
You may wonder:
Why is my stomach making so much noise?
Most stomach noises are completely normal.
In fact, many of the sounds you think are coming from your stomach are actually produced by your intestines as muscles move food, liquid and gas through your digestive system. These digestive sounds are sometimes called borborygmi.
However, unusually frequent or loud stomach noises accompanied by bloating, diarrhoea, constipation, vomiting or abdominal pain can sometimes indicate a digestive problem.
Here are eight possible reasons your stomach may be making so much noise.
1. Your Digestive System Is Simply Doing Its Job
Your digestive tract is not silent.
Muscles in the walls of your stomach and intestines repeatedly contract and relax to move food through your digestive system.
This process is called peristalsis.
As these contractions move:
- food
- liquid
- digestive juices
- gas
through your intestines, they can produce gurgling, bubbling and rumbling noises.
So hearing your stomach after eating does not necessarily mean anything is wrong.
It may simply mean your digestive system is working normally.
2. You May Be Hungry
The classic stomach growl commonly occurs when you haven't eaten for several hours.
Your stomach and intestines continue contracting even when they are relatively empty.
Because there is less food inside to muffle the sounds, those contractions can seem much louder.
This explains why your stomach may suddenly announce your hunger during a quiet meeting or while sitting in a classroom.
Eating may temporarily quiet the noise, although digestion itself can also produce sounds afterwards.
3. Gas May Be Moving Through Your Intestines
Gas is a normal part of digestion.
When gas and liquid move together through the intestines, they can create surprisingly loud noises.
You may also experience:
- bloating
- burping
- passing wind
- abdominal fullness
Gas can come from swallowed air and from bacteria in the large intestine breaking down carbohydrates that were not completely digested earlier.
Certain foods naturally produce more intestinal gas than others.

4. You May Be Swallowing Too Much Air
Everyone swallows some air while eating and drinking.
But certain habits can make you swallow more.
These include:
- eating very quickly
- drinking quickly
- drinking through a straw
- chewing gum
- drinking carbonated beverages
The swallowed air eventually has to leave your digestive system.
Some comes back up as burping, while some travels farther through the intestines and can contribute to gas and digestive noises.
Eating more slowly may help if excessive swallowed air is contributing.
5. Certain Foods May Make Your Gut Noisier
Have you noticed that your stomach becomes particularly vocal after certain meals?
Some foods can increase intestinal gas as gut bacteria break them down.
Common examples can include:
- beans
- lentils
- cabbage
- broccoli
- cauliflower
- onions
- peas
- some whole grains
This does not necessarily mean those foods are unhealthy or that you need to avoid them.
Many are highly nutritious.
Instead, pay attention to whether particular foods consistently produce uncomfortable symptoms in addition to ordinary digestive sounds.
6. Lactose Intolerance Could Cause Rumbling After Dairy
If your stomach becomes particularly noisy after consuming milk or dairy products, lactose intolerance is one possibility.
Lactose is the natural sugar found in milk.
People with lactose intolerance do not digest lactose efficiently because they have reduced amounts of the enzyme lactase.
Undigested lactose reaches the large intestine, where bacteria break it down.
Symptoms can include:
- stomach rumbling
- bloating
- excess wind
- abdominal cramps
- diarrhoea
- nausea
Symptoms typically develop after consuming foods or drinks containing lactose.
Do not automatically eliminate all dairy simply because your stomach occasionally makes noise. Several digestive conditions can produce similar symptoms, so persistent problems are better assessed properly.
7. Irritable Bowel Syndrome Could Be Involved
Irritable bowel syndrome (IBS) is a common digestive condition.
People with IBS may experience:
- abdominal pain or cramping
- bloating
- diarrhoea
- constipation
- excessive gas
- changes in bowel habits
Increased digestive noises can occur alongside these symptoms.
Stomach rumbling alone, however, does not mean you have IBS.
The overall pattern of symptoms—particularly recurrent abdominal pain associated with bowel changes—is much more important than noise by itself.
8. Rarely, Unusual Bowel Sounds Can Occur With an Intestinal Blockage
This is much less common but important to recognise.
An intestinal obstruction occurs when food, fluid and gas cannot move normally through part of the bowel.
Very unusual or high-pitched bowel sounds can sometimes occur with obstruction.
Other warning symptoms may include:
- severe abdominal pain or cramping
- significant abdominal swelling
- repeated vomiting
- inability to pass stool
- inability to pass gas
A suspected bowel obstruction requires urgent medical assessment.
The presence of stomach noises by themselves should not make you worry about an obstruction.
The accompanying symptoms are what make the situation concerning.
Why Is My Stomach Making Noises When I'm Not Hungry?
Hunger is only one reason your digestive system makes noise.
Your intestines continue moving throughout the day regardless of whether you feel hungry.
Gas and liquid moving through them can therefore create sounds:
- shortly after eating
- several hours after eating
- while you are resting
- when you are not hungry
So a rumbling stomach is not a reliable signal that you need to eat.
Why Does My Stomach Make Noises After I Eat?
Eating activates your digestive system.
Your stomach and intestines begin moving and mixing food with digestive juices while gradually pushing everything forward.
Gas and liquid moving through the digestive tract can create gurgling and bubbling sounds.
This is usually normal.
Pay more attention when post-meal noises repeatedly occur alongside:
- pain
- severe bloating
- diarrhoea
- vomiting
- other significant digestive symptoms
Why Is My Stomach Gurgling but I Don't Have Any Pain?
This is usually reassuring.
Normal digestion can be surprisingly noisy.
If you otherwise feel well and have:
- no abdominal pain
- no significant bloating
- no vomiting
- no persistent diarrhoea
- no persistent constipation
occasional gurgling usually does not indicate a serious problem.
Henry Ford Health similarly notes that digestive noises are generally normal when they are not accompanied by gastrointestinal symptoms.
Why Is My Stomach Making Noises at Night?
You may notice digestive noises more at night simply because your surroundings are quieter.
Your digestive system does not completely stop working when you go to bed.
Recent meals, gas, hunger and normal intestinal contractions can all produce sounds.
If the noises repeatedly wake you because they occur alongside pain, diarrhoea or other symptoms, that pattern deserves more attention.
Why Is My Stomach Making Noises and I'm Bloated?
Gas is one explanation that can connect these two symptoms.
Gas moving through the intestines can produce both:
- visible or uncomfortable bloating
- rumbling and gurgling sounds
Possible triggers include certain foods, carbonated drinks, swallowed air and food intolerances.
IBS and other digestive conditions can also cause bloating.
Persistent bloating deserves more attention than ordinary occasional stomach noises.
Why Is My Stomach Making Noises and I Have Diarrhoea?
Your intestines may become more active when you have diarrhoea, producing louder or more frequent bowel sounds.
Possible causes include:
- gastroenteritis
- food intolerance
- dietary changes
- IBS
- other digestive conditions
The combination becomes more concerning when diarrhoea is severe, persistent or accompanied by dehydration, significant abdominal pain, blood in the stool, fever or repeated vomiting.
Can Stress Make Your Stomach Gurgle?
Yes, stress and the digestive system are closely connected.
Stress and anxiety can influence intestinal movement and how strongly you perceive digestive sensations.
You may notice more:
- rumbling
- butterflies
- urgency
- abdominal discomfort
during stressful situations.
However, persistent gastrointestinal symptoms should not automatically be blamed on stress without considering other explanations.
How Can I Reduce Loud Stomach Noises?
You cannot—and do not need to—make your digestive system completely silent.
But several habits may reduce excessive noises.
Eat more slowly
Eating quickly can cause you to swallow additional air.
Slow down and chew your food properly.
Consider smaller meals
Large meals can increase digestive activity and may worsen symptoms in some people.
Reduce fizzy drinks if they trigger symptoms
Carbonated drinks introduce additional gas into your digestive system.
Identify individual food triggers
If certain foods consistently cause uncomfortable bloating, diarrhoea or excessive gas, keep a simple food-and-symptom diary.
Stay physically active
Gentle movement can help normal digestive activity.
Do not unnecessarily restrict your diet
A noisy stomach by itself is not a reason to eliminate gluten, dairy or entire food groups.
Unnecessary restrictive diets can make it harder to get adequate nutrition.
When Should You See a Doctor About Stomach Noises?
Stomach sounds themselves rarely require medical treatment.
Consider medical advice when persistent or unusually loud digestive noises occur alongside:
- recurring abdominal pain
- significant bloating
- persistent diarrhoea
- persistent constipation
- repeated nausea or vomiting
- blood in your stool
- unexplained weight loss
- loss of appetite
- a significant change in bowel habits
Henry Ford Health recommends medical assessment when bothersome stomach noises accompany symptoms including abdominal pain, cramping, bloating, nausea, vomiting, diarrhoea, rectal bleeding or constipation.
Seek urgent medical attention for severe abdominal pain, repeated vomiting, major abdominal swelling and inability to pass stool or gas, as this combination can occur with an intestinal obstruction.
Frequently Asked Questions
Is a noisy stomach healthy?
Usually.
Bowel sounds are a normal consequence of muscular contractions moving food, liquid and gas through your digestive tract.
Does stomach growling always mean you're hungry?
No.
Hunger can make digestive noises more noticeable, but your intestines can rumble while digesting food or moving gas and liquid even when you are not hungry.
Why is my stomach so loud after eating?
Eating increases digestive activity. Muscular contractions move food and liquid through your digestive system, sometimes producing loud sounds.
Can gas make your stomach make noises?
Yes. Gas moving alongside fluid through the intestines is one of the main reasons digestive sounds can become audible.
Can lactose intolerance cause stomach rumbling?
Yes. Lactose intolerance can cause stomach rumbling along with bloating, wind, abdominal discomfort and diarrhoea after consuming lactose-containing foods.
Should I worry if my stomach is constantly gurgling?
Noise alone is usually less important than the symptoms accompanying it.
Persistent gurgling associated with pain, significant bloating, vomiting or changes in bowel habits deserves medical assessment.
Can I stop my stomach from making noises completely?
Probably not—and you shouldn't need to.
Normal bowel sounds are part of a functioning digestive system.
The Bottom Line
If you're wondering “Why is my stomach making noises?”, the answer is usually reassuring.
Your digestive system is constantly moving food, liquid and gas, and those movements naturally produce growling, rumbling and gurgling sounds.
Hunger can make them louder, but your stomach can also make noise after eating or when you are not hungry.
Gas, swallowed air and certain foods can increase the sounds, while conditions such as lactose intolerance or IBS may be relevant when other digestive symptoms are present.
The most important thing is not how loud your stomach is, but what else is happening alongside the noise.
Ordinary rumbling without pain or other symptoms is generally normal. Persistent noises accompanied by significant pain, vomiting, bloating, diarrhoea, constipation or other concerning symptoms should be medically assessed.
