Hi doctor. The doctor said, I have bad breath, but when I breathe out through my nose, I also have an odor, I wake up feeling nauseous, so do I have a sore throat?

I often have nausea in the morning (after drinking water or eating breakfast), feeling of not eating well. So the doctor asked me if nausea or vomiting in the morning caused HP virus infection?

I often feel nauseous in the morning (after drinking water or having breakfast), not having a good appetite. The doctor asked me if I feel nauseous in the morning, is it HP infection? Thank you doctor.
