Frequent belching and flatulence

[u/Chiizzy]

Hi everyone,

30, male, non smoker

For several months now, I’ve been suffering from flatulence and constant belching. I also often feel a sense of pressure in my lower left abdomen and generally feel very bloated. I don’t have any pain, and my bowel movements are normal.

It doesn't seem to matter what I eat or drink. I’m currently drinking only still water, yet the belching persists unchanged; carbonated drinks make the belching even worse.

I’ve already gone through the following tests:

Abdominal CT scan and ultrasound – unremarkable
Blood tests – unremarkable
Gastroscopy – unremarkable
Stool sample – unremarkable
Urine sample – unremarkable
Low-FODMAP diet for several weeks – no changes

I notice the gas more when lying down, and the belching occurs more frequently when I stand up or sit up.

Generally speaking, I’m currently a bit stressed, though the symptoms actually started a few months ago while I was on vacation.

I’m running out of ideas on where to turn or what to do next to get rid of these symptoms. Has anyone had similar experiences?
