@idkaren . I also went to see a dietician too. I had her research why illnesses and she helped with which foods to eat and those not too.
Many of the foods in my normal diet. Like hot peppers. Aggravated the issues..
Did your dr give you foods not to eat for awhile and slowly introduce back in your diet?

Asparagus did not settle well in my system. Now I can it.. I notice beets take awhile to digest now. When before surgery I never had an issue..

But do let your dr know about the issues after eating. Keep a log of your foods..

Wishing you the best. It takes time to heal. So don't panic..
