I often feel nauseous.

It seems like they are constantly saying they feel nauseous.

I'm not dizzy, but I keep feeling a queasy sensation in my stomach.

I don't usually eat very spicy or salty foods, but my stomach doesn't feel well, and when I get a gastroscopy, the results come back normal, so I don't know how to resolve this.

It's a bit too quick to dismiss it as just a nervous condition; even eating a little more makes me feel nauseous, and I feel nauseous even when I'm hungry.

I feel overwhelmed because I don't know the solution.
