Why my stomach making noise?

I have always wanted to know why my stomach making noise. I don't know why, do you ? I always been thinking maybe because I am feeling hungry. Well, if you don't know why like me.

Let's read about it Stomach Noice at this link. My sister used to have gastric and I think she can read about this as well.

If I don't eat before sleep, in middle of the night I would be waking up and first call is always from my stomach. The growling sound, talking about this I have a funny thought as my sister used to ask me is that your stomach growling sound? Why? Are you hungry?

Have anyone think about record the sound of your stomach?
