I'm Trying to understand my Radiologist Impressions!!

[FonsoPR]

Hi everyone. My Doc send me for a barium swallow test and the impression were.

1) Small hiatal hernia.
2) Prominent gastric folds at the cardia level.

I know what to do with the first impression and I know what is that. BUT the second one I really have NO idea what it is and what to do with that problem. Believe it or not I show this results to a General Doctor before I have to show this to a Gastroenterologist and the General Doc told me that he does NOT know what is the second impression. Please is somebody know what is that and what to do I really will be grateful.

Thanks
