If your food allergies are causing Diarrhea then the Diarrhea can cause the ion imbalances that could cause Vertigo. It would have to be chronic Diarrhea though.

It is a better bet to just go to an ENT (Ears Nose and Throat) doctor and have them do some standard testing for vertigo problems. There are several things they test for that are a lot more common triggers of Vertigo than anything food allergy related.

Either way, the solution medicines are typically ones prescribed by an ENT.

A drop in blood pressure from an allergic reaction can also cause vertigo.

thank you so much for replying will go see an ENT good idea
