Is there any link to ulcers and bad breath?

Question

My bf's breath was never bad before, but he was recently diagnosed with a stomache ulcer and now his breath is just horrendous. I let him know, but DAYUM, I can't even look his way now, especially in the morning!

Answer 1

I don't know about ulcers, but he could have cavities, they'll cause atrocious breath that smells like death.
