Jacky asked:
I have had really bad breath and I think it may be coming from my stomach..
I regularly swish peroxide, mouthwash, I brush and floss daily.
still nothing kills the bad breath.
I was wondering what stomach conditions can cause this? I have been really stressed out lately and have noticed a bad pain in my lower left abdominal area. also I have had a lot of nausea, ulcer? something else?
yes I know I need to go to the doctor…im just trying to narrow down what might be wrong
anyone have any ideas? thanks in advance

It could be gingivitis, and yes get to the doctor.
Lots of time it is sinus problems that cause this so make sure your sinuses are not clogged up or infected.
Diet also has an effect. If you are on a carb only diet, your breath will stink for awhile
Good luck
u need to quickly seek advice if you think you have got a ulcer there could be a danger of it bursting it could be fatal
It could also be a gum infection (periodontis) or tooth abscess.
eating yogurt can reduce halitosis
