Great question Emma! Ahhh yes, my stomach growls all the time when I m hungry. Why is that? Well it’s commonly associated with hunger, but it can occur at any time, on an empty or full stomach (and also in the intestine). The growling is just a lot louder when the stomach and intestines are empty because there’s no food present to muffle the noise. So what is this growling caused by anyways? It’s muscular activity in the stomach and small intestines… they are composed of layers of smooth muscle that push the food along from your stomach to your anus. When the wall muscles are activated and squeeze the tract’s contents to mix and propel food, gas and fluids through the stomach and small intestines, it generates a rumbling noise. So there you go, next time someone complains about our loud stomach we can tell them that it is hard at work 😉 Hope that helps to answer your question!

Great question Emma.
First of all grumbling probably isn’ caused by your stomach at all, but by your upper and lower intestines, which is where your food goes after your stomach has broken it down a littl bit. Your intestines are where the rest of your food is broken down and where you absorb the goodness from the food and drink that you eat. This is done by the squeezing of these tubes in a rhythm which slowly moves it down towards (ahem)…….! When your food is being digested, a little gas is released, which creates small pockets of this gas. With all the squeezing and liquid, sometimes this can make noises moving from one party to another!
This happens to everyone, and may be down to what you eat and how you exercise.
