Why Does The Stomach Make Sounds is a common question. At WHY.EDU.VN, we delve into the fascinating world of digestive noises, offering a clear understanding of what causes those gurgles, growls, and rumbles in your abdomen. Discover the reasons behind stomach noises, from normal digestive processes to hunger pangs, and learn when these sounds might indicate a more serious issue. Explore potential causes and remedies for noisy stomach, borborygmi, and digestive health concerns.
1. Understanding Borborygmi: The Science Behind Stomach Sounds
Borborygmi is the medical term for the rumbling, gurgling sounds your stomach makes. These sounds are a normal part of digestion and occur due to the contraction of muscles in the walls of your digestive tract. These contractions, known as peristalsis, mix and move food, fluids, and air through your intestines.
1.1. The Role of Peristalsis
Peristalsis is essential for digestion. These rhythmic contractions propel food from the esophagus to the stomach, then through the small and large intestines, and finally to the rectum for elimination. The sounds you hear are a result of this process, where the churning and squeezing of food, combined with gas and digestive fluids, create a symphony of noises.
1.2. What is Normal Borborygmi?
Normal borborygmi are typically soft, intermittent, and not accompanied by any other symptoms. They can occur at any time, whether you are hungry or have just eaten. It’s important to recognize that occasional stomach noises are a sign that your digestive system is working as it should.
1.3. What is Abnormal Borborygmi?
Abnormal borborygmi, on the other hand, are excessively loud, frequent, and often accompanied by symptoms such as abdominal pain, bloating, gas, diarrhea, or constipation. These sounds might indicate an underlying digestive issue that requires medical attention.
2. Common Causes of Stomach Noises
Several factors can contribute to why the stomach makes sounds. While some are normal and harmless, others may indicate an underlying issue. Here’s a detailed look at the most common causes:
2.1. Hunger and Ghrelin
One of the most well-known causes of stomach noises is hunger. When you’re hungry, your brain signals your stomach to release a hormone called ghrelin. Ghrelin stimulates gastric motility, causing the muscles in your stomach and intestines to contract. This contraction leads to the familiar growling sound we associate with hunger pangs.
2.2. Digestion After Eating
Stomach noises after eating are also common and typically normal. As food enters your stomach, it triggers a series of digestive processes. Peristalsis intensifies to mix the food with gastric juices and move it through the digestive tract. This process creates gurgling and rumbling sounds as the food, fluids, and gas are churned and propelled forward.
2.3. Gas and Air Swallowing
Gas is a natural byproduct of digestion, produced when bacteria in your colon ferment undigested carbohydrates. Swallowing air while eating, drinking, or talking can also introduce gas into your digestive system. The movement of this gas through the intestines can create various noises. Certain foods, such as beans, broccoli, and carbonated drinks, are known to produce more gas.
2.4. Irritable Bowel Syndrome (IBS)
Irritable Bowel Syndrome (IBS) is a common gastrointestinal disorder that can cause a variety of symptoms, including abdominal pain, bloating, gas, diarrhea, and constipation. Increased stomach noises are often reported by individuals with IBS due to altered gut motility and sensitivity.
2.5. Food Intolerances and Allergies
Food intolerances, such as lactose intolerance, and food allergies can cause digestive upset and increased stomach noises. Lactose intolerance, for example, occurs when the body doesn’t produce enough lactase, the enzyme needed to digest lactose, the sugar found in milk and dairy products. This can lead to gas, bloating, and loud stomach noises after consuming dairy.
2.6. Medications
Certain medications can affect digestive function and contribute to stomach noises. Antibiotics, for example, can disrupt the balance of bacteria in your gut, leading to digestive upset and increased gas production. Other medications, such as antacids and laxatives, can also affect gut motility and cause stomach noises.
2.7. Stress and Anxiety
Stress and anxiety can have a significant impact on your digestive system. When you’re stressed, your body releases hormones that can affect gut motility, leading to changes in digestion and increased stomach noises. Stress can also worsen symptoms of digestive disorders like IBS.
2.8. Bowel Obstruction
In rare cases, excessively loud stomach noises accompanied by severe abdominal pain, vomiting, and constipation could indicate a bowel obstruction. A bowel obstruction is a serious medical condition that requires immediate attention. It occurs when the normal flow of digested material through the intestine is blocked, leading to a buildup of fluids and gas.
2.9. Infections
Gastrointestinal infections, caused by viruses, bacteria, or parasites, can lead to inflammation and increased activity in the digestive tract, resulting in louder and more frequent stomach noises. These infections often cause other symptoms such as diarrhea, vomiting, and abdominal pain.
3. How to Differentiate Normal From Abnormal Stomach Sounds
It’s crucial to distinguish between normal digestive noises and those that might indicate a problem. Here’s a guide to help you understand the difference:
3.1. Normal Stomach Sounds
- Frequency: Occasional and intermittent
- Intensity: Soft to moderate
- Associated Symptoms: None
3.2. Abnormal Stomach Sounds
-
Frequency: Frequent and persistent
-
Intensity: Loud and excessive
-
Associated Symptoms:
- Abdominal pain
- Bloating
- Gas
- Diarrhea
- Constipation
- Nausea
- Vomiting
- Fever
- Weight loss
- Blood in stool
If you experience abnormal stomach sounds accompanied by any of the above symptoms, it’s important to seek medical advice from a healthcare professional.
4. Medical Conditions Associated With Increased Stomach Noises
Several medical conditions can cause increased stomach noises as a primary or secondary symptom. Here are some of the most common:
4.1. Irritable Bowel Syndrome (IBS)
IBS is a chronic gastrointestinal disorder characterized by abdominal pain, bloating, and changes in bowel habits. Individuals with IBS often experience increased stomach noises due to altered gut motility and visceral hypersensitivity.
4.2. Inflammatory Bowel Disease (IBD)
Inflammatory Bowel Disease (IBD), which includes Crohn’s disease and ulcerative colitis, is a group of chronic inflammatory conditions that affect the digestive tract. Inflammation can disrupt normal digestive processes, leading to increased stomach noises along with other symptoms like abdominal pain, diarrhea, and weight loss.
4.3. Small Intestinal Bacterial Overgrowth (SIBO)
Small Intestinal Bacterial Overgrowth (SIBO) occurs when there is an excessive amount of bacteria in the small intestine. This can lead to fermentation of undigested food, producing gas and causing increased stomach noises, bloating, and abdominal discomfort.
4.4. Food Intolerances
Food intolerances, such as lactose intolerance or gluten intolerance, can cause digestive symptoms, including increased stomach noises, when the offending food is consumed. These intolerances result from the body’s inability to properly digest certain food components.
4.5. Celiac Disease
Celiac disease is an autoimmune disorder triggered by gluten, a protein found in wheat, barley, and rye. In individuals with celiac disease, gluten consumption damages the small intestine, leading to malabsorption and digestive symptoms, including increased stomach noises, diarrhea, and abdominal pain.
4.6. Gastroparesis
Gastroparesis is a condition in which the stomach empties too slowly. This can lead to nausea, vomiting, abdominal pain, and increased stomach noises. Gastroparesis is often caused by damage to the vagus nerve, which controls stomach muscle contractions.
5. Practical Tips to Reduce Excessive Stomach Sounds
While some stomach noises are normal, there are several strategies you can employ to minimize excessive or unwanted sounds:
5.1. Mindful Eating Habits
- Eat Slowly: Eating too quickly can lead to swallowing excess air, contributing to gas and stomach noises.
- Chew Thoroughly: Proper chewing aids digestion by breaking down food into smaller particles, reducing the burden on your digestive system.
- Avoid Talking While Eating: Talking while eating can cause you to swallow more air.

8.4. Food Intolerances
Treatment for food intolerances involves avoiding the offending food. Enzyme supplements, such as lactase for lactose intolerance, may help improve digestion.
8.5. Celiac Disease
Treatment for celiac disease involves strictly adhering to a gluten-free diet. This allows the small intestine to heal and prevents further damage.
8.6. Gastroparesis
Treatment for gastroparesis may involve dietary modifications, medications to improve stomach emptying, and in severe cases, surgery to place a feeding tube into the small intestine.
9. The Gut-Brain Connection: How Emotions Affect Digestion
The gut-brain connection refers to the bidirectional communication between the digestive system and the brain. This connection plays a significant role in regulating digestion, mood, and overall health. Stress, anxiety, and depression can affect gut motility, inflammation, and gut bacteria composition, leading to digestive symptoms like increased stomach noises, bloating, and abdominal pain.
9.1. Stress and Digestion
When you’re stressed, your body releases stress hormones like cortisol, which can affect digestive function. Stress can slow down digestion, leading to constipation, or speed it up, leading to diarrhea. It can also increase gut sensitivity, making you more aware of stomach noises and other digestive sensations.
9.2. Anxiety and Gut Motility
Anxiety can affect gut motility, leading to changes in bowel habits. Some people experience increased gut motility and diarrhea when anxious, while others experience decreased gut motility and constipation. Anxiety can also increase the production of gas in the digestive tract, leading to bloating and stomach noises.
9.3. Depression and Gut Health
Depression has been linked to changes in gut bacteria composition. Studies have shown that individuals with depression often have lower levels of beneficial gut bacteria and higher levels of harmful bacteria. These changes in gut bacteria can affect digestion and contribute to digestive symptoms.
9.4. Strategies to Improve the Gut-Brain Connection
- Stress Management: Practice stress-reducing techniques like yoga, meditation, or deep breathing exercises.
- Mindful Eating: Pay attention to your food and eat slowly in a relaxed environment.
