Stomach growling, medically known as borborygmi, is a common and usually harmless occurrence. While it’s often associated with hunger, the rumbling sounds emanating from your abdomen are a natural part of digestion. However, if your stomach seems to growl incessantly, you might wonder why and what you can do about it. This article delves into the reasons behind persistent stomach growling and provides practical strategies to manage it.
Understanding the Growl: What’s Really Happening?
The noises you hear from your stomach are primarily due to the movement of your digestive system as it processes food, liquids, and gases. Even when your stomach is empty, it doesn’t remain inactive. Your intestines and stomach undergo a process called peristalsis, which involves muscle contractions that push contents through the digestive tract.
When your stomach is empty for a few hours, it releases hormones that signal the brain to initiate the migrating motor complex (MMC). This process is essentially a cleansing wave that sweeps through your digestive system, pushing any leftover food and secretions into the large intestine. The growling sounds are the result of these intestinal and stomach contractions combined with the gurgling of fluids and gases in an empty or partially empty digestive tract.
Common Reasons for Frequent Stomach Growling
While occasional stomach growling is normal, persistent or excessive growling can be bothersome. Here are several common reasons why your stomach might keep growling:
1. Hunger
This is the most widely recognized reason. When your stomach has been empty for a couple of hours, it starts signaling that it needs food. The MMC activity increases, leading to noticeable growling sounds as your digestive system prepares for an incoming meal.
2. Normal Digestion
Even after you’ve eaten, your stomach will growl as part of the normal digestive process. Food and fluids are mixed and broken down, and gases are produced as a byproduct. These movements and byproducts naturally create sounds within your digestive system.
3. Gas and Indigestion
Excessive gas in your digestive tract can amplify stomach growling. Gas can be produced from the breakdown of certain foods or from swallowing air when eating too quickly. Indigestion, which can be caused by eating too much, eating fatty foods, or consuming irritating substances, can also lead to increased digestive activity and noises.
4. Certain Foods and Drinks
Certain dietary choices can contribute to more frequent stomach growling:
- Sugary Foods and Drinks: Foods high in fructose and sugar alcohols like sorbitol can be poorly absorbed in the small intestine, leading to fermentation in the large intestine and gas production.
- Alcohol: Alcohol can irritate the digestive tract, increase stomach acid production, and cause inflammation, all of which can contribute to stomach noises.
- Acidic Foods: Foods like citrus fruits and coffee can also stimulate stomach acid production, potentially leading to more growling.
5. Gas-Producing Foods
Certain foods are known to produce more gas during digestion. These include:
- Beans and lentils
- Broccoli, cabbage, and cauliflower
- Onions
- Carbonated drinks
Identifying and limiting these foods can sometimes reduce excessive stomach growling if gas is a primary culprit.
6. Food Intolerances
Food intolerances, such as lactose intolerance, can lead to increased gas production and digestive noises. Lactose intolerance occurs when the body doesn’t produce enough lactase, the enzyme needed to digest lactose in dairy products. Undigested lactose ferments in the colon, causing gas, bloating, and growling.

7. Large Meals and Eating Habits
Eating very large meals, especially those high in fat and sugar, can overwhelm the digestive system and lead to more noticeable stomach growling. Eating quickly can also cause you to swallow excess air, contributing to gas and rumbling.
8. Stress and Anxiety
Stress and anxiety can significantly impact digestion. During stressful situations, the gut-brain connection is activated, often leading to increased gut motility and sensitivity. This can result in more pronounced stomach growling, even if you’re not hungry.

9. Underlying Gastrointestinal Issues
In some cases, persistent and bothersome stomach growling, especially when accompanied by other symptoms, could indicate an underlying gastrointestinal condition such as Irritable Bowel Syndrome (IBS) or, less commonly, an intestinal blockage or infection.
Strategies to Reduce Stomach Growling
While you can’t completely eliminate stomach growling (as it’s a natural process), you can take steps to minimize excessive or embarrassing noises:
1. Drink Water
Drinking a glass of water can help to quiet a growling stomach, especially if you’re not able to eat immediately. Water helps with digestion and can also fill your stomach, temporarily reducing growling sounds.
2. Eat Smaller, More Frequent Meals
Instead of three large meals, try eating smaller meals or snacks every few hours. This can help keep your stomach from being completely empty, potentially reducing hunger-related growling.
3. Chew Food Thoroughly and Eat Slowly
Chewing food properly aids digestion from the start and reduces the amount of air you swallow while eating. Eating slowly can also decrease air swallowing and give your body time to register fullness, preventing overeating.
4. Limit Trigger Foods and Drinks
Reduce your intake of sugary foods, alcohol, and acidic beverages, especially if you notice they trigger stomach growling.
5. Identify and Manage Gas-Producing Foods
Keep track of foods that seem to cause you gas and excessive growling. Limiting your consumption of beans, cruciferous vegetables, and carbonated drinks might help.
6. Consider Food Intolerance
If you suspect a food intolerance, such as lactose intolerance, talk to your doctor. They can help you determine if you have an intolerance and advise on dietary changes, such as limiting or avoiding dairy products.
7. Practice Portion Control
Avoid overeating by practicing portion control. Smaller meals are easier for your digestive system to process and can reduce gas buildup and subsequent growling.
8. Stay Active
Light physical activity, like a walk after meals, can aid digestion and help food move through your system more efficiently, potentially reducing stomach rumbling.
9. Manage Stress
Practice stress-reduction techniques such as deep breathing exercises, meditation, or yoga. Managing stress can help regulate your gut-brain axis and reduce stress-related digestive noises.
When to Seek Medical Advice
While stomach growling is usually benign, consult a doctor if your stomach growling is:
- Excessive and persistent
- Accompanied by pain, bloating, diarrhea, constipation, nausea, or vomiting
- Associated with unexplained weight loss
- Disrupting your daily life
These symptoms could indicate an underlying medical condition that needs to be addressed.
Conclusion
Stomach growling is a normal bodily function reflecting the active processes of digestion. While it can be embarrassing at times, understanding why your stomach keeps growling and adopting simple lifestyle and dietary adjustments can help manage excessive noises. If you’re concerned about persistent or symptomatic stomach growling, seeking medical advice is always a prudent step to ensure your digestive health.
