Stomach Growling – Why Does My Stomach Make Noises?

Have you ever found yourself in a quiet room and got interrupted by strange gurgling, growling, or rumbling sounds from your stomach? You’re not alone! Many of us have experienced these audible stomach noises and wondered what causes them. In this blog, we will explore the fascinating world of stomach sounds and uncover the reasons behind these intriguing rumblings. So, let’s dive in and shed some light on the question: “Why does my stomach make noises?”

The Digestive Symphony

Digestive Symphony

Our digestive system is a complex orchestra of organs working in harmony to break down food, absorb nutrients, and eliminate waste. During this process, various movements occur within the gastrointestinal tract, leading to the production of noises known as borborygmi.

Hunger Pangs

Hunger Pangs

The most familiar stomach sounds are hunger pangs, which often occur when our stomach is empty. When our body needs sustenance, it releases a hormone called ghrelin, which stimulates contractions in the stomach. These contractions mix and propel air, fluids, and stomach acids, creating the rumbling noises we hear.

Gas & Swallowing Air

Gas Swallowing

Another common cause of stomach noises is the presence of gas. When we eat or drink, we inadvertently swallow small amounts of air. This air can accumulate in our digestive system and cause the intestines to contract, leading to gurgling or bubbling sounds. Certain foods or carbonated beverages can also increase the amount of gas produced in the gut.

Peristalsis & Gut Motility

Gut Motility

The movement of food through the digestive system is facilitated by a process called peristalsis. This rhythmic contraction and relaxation of the intestinal muscles help propel food forward. As peristalsis occurs, it can generate audible sounds as the contents of the intestines move along.

Irritable Bowel Syndrome (IBS) & Digestive Disorders

Digestive Disorder

In some cases, excessive stomach noises may be associated with digestive disorders like Irritable Bowel Syndrome (IBS). IBS is a chronic condition characterized by abdominal pain, bloating, and changes in bowel habits. These symptoms can be accompanied by increased gut sensitivity and hyperactive bowel sounds.

Stress & Nervousness

Stress and Nervousness
The gut-brain connection is a fascinating aspect of human physiology. When we experience stress, anxiety, or nervousness, our brain sends signals to the gut that can disrupt the normal digestive process. This can result in increased gut motility and, consequently, more noticeable stomach noises.

Medical Interventions & Medications

Certain medical interventions, such as gastrointestinal surgeries or endoscopies, can temporarily affect the normal functioning of the digestive system. This can lead to altered gut motility and increased stomach noises during the recovery period. Additionally, certain medications or dietary supplements may cause gastrointestinal side effects that result in audible sounds.


The human digestive system is a marvel of biology, but it’s not always a silent one. Stomach noises are a normal part of digestion and are often harmless. However, if you experience persistent or severe symptoms like abdominal pain, bloating, or changes in bowel habits, it is essential to consult a healthcare professional for a proper diagnosis and treatment. So, the next time your stomach starts making noises, embrace it as a natural part of being human. It’s a reminder that your body is hard at work digesting and nourishing itself. And remember, even the loudest rumbles will pass, leaving you with nothing more than a story to tell and a greater understanding of your incredible digestive system.
