Why do our stomachs rumble?
Thanks for asking. It can be embarrassing when your stomach rumbles in public, but it's actually a totally natural bodily function.
The scientific name for those rumbles or growls is Borborigmi, a term invented by the ancient Greeks.
We tend to associate stomach rumbles with hunger, but that's not totally accurate.
In reality, our stomachs rumble all the time, whether we're hungry or not.
It's just that when the stomach is empty, the noise becomes more apparent.
That's because when the stomach is full, its contents muffle the sounds.
What actually causes the rumbles?
Our digestive tract is the passageway through the body from mouth to anus.
In order to digest food properly, it triggers muscular contractions through an involuntary physiological process called peristalsis.
That helps propel food through the contraction of the muscles in the stomach and intestines.
It's important for ensuring effective digestion, as food is mixed with saliva and gastric juices to transform it into nutrients.
At this point, pockets of gas and air form.
These pockets of air are compressed when the intestine contracts, especially during digestion, which is when the stomach starts to rumble.
Can certain factors increase stomach rumbling?
Yes, stress or swallowing too much air can accentuate the rumblings.
In fact, contractions in the digestive tract are increased.
Fizzy drinks can also have the same effect on the stomach.
To reduce their intensity, you should stick to a balanced diet.
Chew your food well before swallowing and breathe calmly to avoid taking too much air into the digestive tract.
Experts also advise having a hot or cold drink after your meal to increase digestive secretions.
Another option is to apply light pressure to the stomach to stimulate contractions in the digestive tract.
Should I be worried if the rumblings are intense?
If the noises are accompanied by bloating, pain or bowel movement problems like diarrhea or constipation, it's best to consult a gastroenterologist.
They'll use a stethoscope to listen to the rumblings.
They may also prescribe an ultrasound to look more closely at digestive activity in your stomach.
To sum up, stomach rumblings on their own shouldn't be a cause for concern.
But if there are other symptoms too, you'll want to make sure there isn't an underlying health issue.
