Hello. I would like to help you find an answer.
2 things that come to mind are celiac disease and irritable bowel.
I suggest you see a GI doctor to evaluate.
Thanks for the accept. Don't forget positive feedback. I appreciate it. :)
If you need more help, please ask.
Yes, most likely if it were structural.
However, you wouldn't be able to detect IBS or celiac on a scan.
