Stomach Sitting Pin My Stomach Grunts All Day Is This A Sign Of A Serious Problem?

My stomach grunts all day is this a sign of a serious problem? - stomach sitting pin

My stomach is growling horribly, sometimes very hard I think my colleagues think farts sitting here at my desk. It tends to be stronger if I go to the toilet and not the number two, while most of the time, just grunting noises. I also have a very strong gas is terrible morning. I've tried all the things I like to write the pin number, what could be causing my problem, but nothing really stands out.
Assistance, as if me and my friend really did not know this problem .. LOL
