Ever wondered, “Why is my stomach growling?” Let’s explore.
I recently heard that the stomach doesn’t growl solely because it’s hungry. I’m not sure about you, but this is what I always thought.
Well, mostly anyways.
When my SIBO was at its worst, I can distinctively remember pushing on the (right more than left) lower side of my stomach and hearing it “slosh.”
Yes, I heard a weird noise and called it sloshing. Maybe you know what I’m talking about?
It was a form of rumbling and growling, but rarely did I feel hungry when it happened. Thus, I knew the noises the stomach makes are about much more than just hunger.
So I started exploring.

If you want to sound super intelligent the next time your stomach starts rumbling say, “This borborygmi is really loud today.” Borborygmi is the technical name for the sound gas makes as it works its way through the intestines.
However, you likely refer to borborygmi as stomach growling, rumbling, sloshing, churning, etc.
According to the International Foundation for Gastrointestinal Disorders,
In order for the bowel (intestines) to be heard, three conditions must be met:
- Muscular contraction of the intestinal wall
- The presence within the intestines of liquid
- The presence within the intestines of gas
But what are some of the reasons for those three things?
8 Reasons for Stomach Growling

- Your food is moving through the digestive system, supplying nutrients.
- The muscles in your stomach and small intestines are squeezing together to push food, liquids, and gases through your gastrointestinal tract.
- Your stomach is almost empty. The stomach and small intestine muscles are still moving, but now there is mostly just air and only a little liquid and food. So when the muscles of the stomach and small intestines squeeze, those gurgling gases and liquids inside your empty stomach are easier to hear.
- You are relaxed from an activity such as massage. “When you’re relaxed, your digestive system starts to really break down the food that you’ve ingested, and obviously, depending on what you’ve eaten, sometimes you also have movement of gas through your digestive track and through your intestine.”
- Eating too fast. When you eat too fast, you also swallow a lot of air. Your stomach will growl when it has a hard time breaking all that extra air down.
- Food intolerance. If you have a sensitivity to a specific food, your stomach and intestines will react upon eating it (usually, not always).
- Disease and/or overgrowths. “Intestinal malabsorption due to intestinal bacterial overgrowth or celiac disease can also cause these symptoms.”
- Indigestion. This one could accompany others on the list (#5), but general indigestion is a reason.
While there are many reasons your stomach is rumbling, they all come back to peristalsis.
Remember from Your Digestive System,
In a healthy gut, food moves through the GI tract through a process called peristalsis, which is a wave-like movement that helps push food forward.
The reason you, as a Gutsy girl are searching, “Why is my stomach rumbling” likely boils down to peristalsis and the MMC (Migrating Motor Complex).
Why do we also hear them when there is no food in our stomachs?
That is down to something called the Migrating Motor Complex, (MMC), a specific type of electrical pulse that triggers peristalsis in the digestive system.
This is thought to serve a house-keeping function, clearing out any leftover food particles, mucus, bacteria or other debris from the stomach and small intestine. source
If any part of that is off in your digestive system, you might be hearing loud noises more often than not.
On the flip side, not all noises are negative. Many of them are simply part of the normal digestive process.
The way to know whether your rumbling stomach is “normal” or not is to consider other symptoms and, of course, via official diagnostic tools and testing.
