The sound inside my stomach is too loud.

The sound inside my stomach is too loud.

It's the sound I make when I'm hungry, a rumbling sound.

But that sound really is very loud.

It's enough to hear even if it's not right next to you.

First, I can't tell if it's the sound of food being digested or if it's really hunger causing the stomach to growl.
Once a sound occurs, it lasts for almost 30 minutes with loud noise, and sometimes other sounds are made in the office to hide this noise.

I wonder if there's a problem with my digestive system;;; When I went to the local clinic for a cold, I asked about it, and they just said it could be normal;;;

Which department should I visit in this situation? It's unclear where this sound is coming from, so it's a bit tricky.

I wish it would stop as a temporary phenomenon, but seeing it go on for months, I don't think it will be temporary.
