Why Does Your Stomach Make Noises?

October 22, 2019


Our digestive systems seem to like making
noise — especially when we most desperately do not want them to be making strange gurgling
sounds. [gurgle] And I mean, even though stomach-growling is
probably one of the less offensive noises your guts can produce, it’s still not something
you want happening in the middle of a thoughtful pause during a job interview. Now, you’d think that simply eating right
before that important meeting would avoid that problem. Because if you’re not hungry,
your stomach isn’t going to growl, right? Well, it might help a little, but you could
still be in for some awkward moments. Because even though stomach rumbles do have something
to do with hunger, that’s not their immediate cause. Instead, those noises are caused by the movement
of air through your digestive tract. And even though that air isn’t actually escaping
your body, it does create some distinctive acoustic effects. Your digestive system moves things around
using muscle contractions. Mostly, it’s just trying to transport partially digested
food, but in the process, air gets shifted around, too, creating sound vibrations. In your stomach and small intestine, that
air makes a noise that’s sorta like when you blow bubbles through a straw in your drink
— except that the bubbles are either moving up toward your stomach or down toward your…
other end. Hunger can make it worse, too. Being hungry
causes extra muscle contractions to flare up, because your digestive system has to clear
out the remains of your last meal to prepare for the next round of food. When you eat, not only that does help calm
down those contractions, but having some food in there also helps muffle the sound a little. But in the end it doesn’t really matter
if you’re hungry or not because if your digestive system is active, it’s going to
make noise. And like the rest of your bodily functions, there’s not a whole lot you can
do about it. A big thanks to Sarah A, a supporter on Patreon,

    Guys,really so embarrassing
    I can't understand what problem do this stomach have….It destroys our personality and more worse if it happens everyday with you and you're like…"oh..no"
    How can anyone concentrate in studies if this continues…
    Spoiling my life
    Even bad when you're a girl and studying in a class where both boys and girls study and stomach growls and boys stare like you as…if…?
    So awkward moment…even during exam times when the whole class is writing I'm just thinking about growls….can't concentrate in studies
    It only growls when all class is silent like..'Yahoo students. ..look am growling' inviting everyone's attention
    However,I'll try to change this but one request from you all..please don't make fun of the person who has this problem. ..support it…so no one will feel embarrassed because it's natural
    Don't bully that person whose stomach growls
    Take care….

    If I’m in class and it starts making noises like that then I just press against my stomach like you do if your about to throw up and that usually stops it.

    But if that doesn’t work then I just punch my self in the guts really hard. People look at me like I’m insane but it works.

    1. Drink 2 cups of COLD water. it stops hunger cravings.
    2. Eat something like oatmeal or fruit. Something filling.
    3. If you made a rumble in class drop your pencim then scoot your chair back. Quickly.

    I was in health class when people were presenting their projects and the room was silent with the exception of the speaker. I had never had a stomach growling problem before and my stomach was growling a little at first so I would just turn the page on my notebook to compensate for the noise, this was working great until I felt that completely empty feeling and I could feel the stomach gas so I shift in my seat to hope it would go away, but instead my stomach decides to let it out all at once with a roar. I panicked and didn’t know what to do to so for some reason I start violently rubbing my notebook papers together but that doesn’t even stop the noise. So I was the guy sitting in the front row (assigned seats) rubbing papers together while my stomach growls louder in a silent room. Btw my classroom has a bunch of hot girls in it and I sit right next to one.
