Part Time Gastroperesis? Is It Possible?

I believe I suffer with a mild/strange form of GP in that it only affects certain foods and not others.

Case in point: Tonight for supper I had white meat chicken, on a sea of noodles  and string beans, all covered in chicken gravy.  Stomach processed it OK.  Later ate grapes that just sat there like a lead weight that I had to force puke out to feel better.

I really should have known better to eat the grapes because grapes ALWAYS "think" there's a STOP SIGN at the exit from my stomach.

Anybody else ever encountered "selective" GP? 

Sounds like you are intolerant to certain foods.  Try eliminating them frim your diet and ask your doctor for tests and in particular, a gastric emptying study.

It could be gluten intolerance.

I would feel bloated and gross until I had to make myself sick to feel better.

Were the noodles wheat based?
