Excessive belching during and after physical exercise

Hi all. Has anyone experienced excessive burping while walking or running? Or during any exercise? This is worrying me coz I am thinking I am going to trigger my GERD and hiatus hernia. I don't want to sit and be unfit because of these conditions. Please help. I stopped exercising last year because I had the same issue. Now I m getting frustrated and discouraged.

A bit late to answer, but still, can be useful to others…
Yes, I have the same issue when I do high impact workout. You need to continue exercising but switch to low impact cardio, or ideally swimming.
