Does it happen as soon as you sit down?  Or while you’re eating?  Or just when you wake up?  Does it happen every morning, or only once a week?
assitant
Can you be more specific?  Can you do it right now, and describe what it sounds like?
assistant
Why does my stomach make a grumbling sound when I am hungry?
user
We need to know a little bit more about what you mean by “grumbling”, and what you mean by “stomach”.  Is this a sound that you hear, or a physical sensation?
assistant
It is a sound I hear.
user
Is it a very loud sound?  Like someone banging a pot? Or a very quiet sound like a mouse behind a couch?
assistant
It is barely audible.
