Hear rumbling sound from your stomach? Ever wondered why our stomach growls when it’s empty?

At times the human body can be somewhat loud. Normally this is the truest when you are hungry – while you’re in an interview for example, on a date with someone, or watching a movie during the time when everyone becomes silent.

It’s generally at particularly these moments that our body then decides that it’s the right time to blow out a loud trumpet of gas or to roar with hunger, the stomach rumble sound.

The initial two are arguably noisy as air is leaving the body through a small opening. Is it just malicious?

Does our body have some wicked sense of humor? Or does this serve a significant role of some sort?

Information about the digestive system

If you own a noisy stomach, then the first thing you need to know is that it’s not only your stomach making all that noise but even your small intestine and the rest of your digestive system to some extent.

Your digestive system is just a long tube that starts from your mouth and goes all the way to your rear end. It also processes the food along the way.

Along with that, it happens to link some organs that perform this role and relies on some muscles to push the food down through the stomach.

This downward motion of the muscles to push the food down is known as ‘peristalsis’.

Another function of these muscles is to mix the food, digestive juices, and liquids together to create a mixture known as ‘chyme’.

The Source of the Noise

So what you now have is a lot of ‘chyme’ being pushed around your stomach. As you can imagine, this displaces a lot of air which gets pressurized out to either end as the food gets pushed in.

The pressurizing action essentially creates noise in the same way that your farts do – only it’s inside your stomach.

Imagine a loud trumpet that is there is a big balloon filled with air. Now when you press either end of the balloon, the air passes through the trumpet and creates noise.

This is perhaps one of the best analogies to think of when it comes to explaining the rumbling of an empty stomach.

Why it happens when you get hungry?

You may be wondering why your stomach makes more noise as and when you get hungry. Would you be noisy if there was food in your stomach?

First of all, having an emptier stomach will free up more area for sound to bounce and reverberate inside.

This is similar to the echo effect in an empty auditorium. You will improve the acoustics of the stomach by having a stomach full of chime that will act like a sound absorbed and save you the shame.

Also if you think further, having an empty stomach is very much similar to a bagpipe. The skin of the stomach will vibrate and add to the sound when it is empty, just like a bagpipe.

At the same time, a hungry stomach begins revving its engine to warm up and get ready for action.

That’s due to the hormones being released that signal your brain that it is the time to eat (which makes you hungry).

In response to the stimulus, the brain tells the muscles to do a ‘final sweep’ of your complete digestive system and to push any of the food that might have stayed stuck the first time.

While you’re hungry, your stomach goes through this process once an hour for 10 to 20 minutes.

How to Prevent a Noisy Stomach?

Now that you know why your stomach produces all that noise, you should be able to work out how to quieten it down.

The first thing that you need to do then is to try to reduce the amount of gas in your stomach as it’s just the air that makes the noise.

You can quickly reduce this air by eating your food slowly and with a closed mouth so that you don’t breathe in much air while you’re chewing.

Another tip that will help you to reduce gas is to eat less of the food that creates gas. You should also reduce taking carbonated drinks which are nothing but flavored gases.

Finally, you should eat multiple small meals throughout the day and not just a few large meals sometimes a day.

This way you’ll be having more food in your stomach meaning your body does not send those signals to start sweeping again more often.

There are various other benefits to eating smaller meals too, including increased metabolism.

So in conclusion, your stomach is nothing but a musical potty pot or that set of bagpipes depending on how you take a look at it.

That grumbling noises are nothing to worry about, but if you feel shy about it then there are several things that you can do to quieten it back down!
