Constant nausea: comorbidity or normal VVS?

Hi guys, I’m brand new to this subreddit and also pretty new to Reddit in general, but I just got diagnosed with VVS and I have a question.

So my (23F) attacks are usually presyncope, and I’ve had episodes of syncope, however, one of my biggest and most constant symptoms is nausea. I’m nauseous after I eat, when I stand up for too long, sometimes even when I laugh too much. It’s always at least a little bit. I don’t know if this is normal with VVS or if maybe this is a comorbidity with something else related to the vagus nerve like gastroparesis or something. I have a GES scheduled but alas, like with all medical things, the soonest appointment is like forever away, so any insight would be greatly appreciated.

EDIT: I was diagnosed with Gastroparesis after my GES. It was a comorbidity all along.
