What Causes Popping Sound In The Stomach?

Hello sometimes i feel a popping sensation in my stomach and it will make gurgling sounds. I know that its not that im hungry because sometimes it happens after i eat. I will also feel sharp pains for no reason in my upper abdomen. Do you know what might be causing this? at first i thought it had to do with eating too much dairy so i started to take a lactose acting relief melt before eating any dairy. that did not do anything, so i just stopped eating dairy but the popping and gurgling does still continue
