Nausea with ibs

I’ve been having nausea that lasts for a day or two then goes away. i have all the things associated under the ibs - including dyspepsia and splendic flexure. which is causing my bouts of nausea? i cant figure it out the last time it happened my bowels were fine. does one if these ailments cause more nausea than the others?

nausea is secondary to IBS. however dyspepsia can give really bad nausea so it’s probably that.
what do you mean by splendic flexure?

Thanks for the reply. My gastro said that air gets trapped in the top curve of the large intestine as it pushes food through which causes gas. I thought he mentioned it could cause nausea.

i dont think that would cause nausea, but it would cause cramps
