Why do our stomachs growl when we are hungry?

Our bodies often reveal what we feel in quite scandalous ways. For example, some people understandably find it difficult to hide their sexual arousal. But if there’s one thing that can’t be hidden, regardless of your genitals, it’s hunger. And that’s it our stomachs growl when we are hungry. At least that’s what we say unofficially. But what actually happens to us is a phenomenon known as Borborygmus.

Guts belong to bosom in colloquial speech. However, borborygmus is a sound that does not begin in the intestines, but in stomach. When we are hungry, it is completely normal and not a cause for concern, although sometimes in certain situations it makes us feel a little uneasy.

But although we all feel it all the time, we usually don’t think about why it happens. So what do we actually hear when we feel hungry?

The sound that makes our stomach growl when we’re hungry

When we eat, we crush the food with our molars and mix it with saliva, causing what is known as Chewing gum, nutritional bolus. This type of porridge passes through the pharynx and esophagus and reaches the stomach, where it mixes with gastric juice and it undergoes some movements known as peristaltic movements, which help break it down into smaller particles. From here, as well as with the help of peristaltic movements, they move to the intestine, where nutrient absorption they will enter the blood and be distributed to the cells that need them. The rest that the body does not need is excreted in the form of waste products.

This is an overgeneralized explanation digestion process. But what interests us is what happens when there are few processed food particles left in the stomach, because most of them have already passed into the intestines.

In this case, it is more difficult for them to continue their course. For example, when we try to empty the remains of a bottle of shower gel. It’s not enough to just throw it as usual. You have to shake it. My stomach is also shaking. It begins to contract, creating movements that mix food and stomach fluids with air. Let’s remember this it’s almost empty here. This mixture air, liquids and food debris Movement is the reason why our stomach growls when we are hungry.

Role of ghrelin

Ghrelin is known as the hunger hormone for obvious reasons. It can be secreted in various parts of the body, such as the pituitary gland, hypothalamus, or even the placenta. But where more of this hormone is released is in stomach.

This release occurs mainly when we have not eaten for a long time. Its main function is to send signals to the brain that increase appetite. But it has many other functions, including stimulating the secretion of gastric juice and stomach movements.

That’s why, when faced with an almost empty stomach, our bowels rumble primarily in these two ways. We are hungry and, on the one hand, we need to empty what is left in the stomach, and on the other hand, prepare it to fill it again. This is how those noises arise that confuse us so much, but about which we should not be upset. After all, they are a sign of good health. It would be much more disturbing to never hear them.
