I have been trying to find a cause of my horrific halitosis, and "H pylori" keeps popping up in my research. Do any of you, who have tested positive for h pylori, suffer from bad breath as one of your symptoms? I have some digestive issues, but no ulcers that I am aware of. I am going to make an appointment with my doctor and hopefully he will test me for h pylori. If anyone has had halitosis from h pylori, please let me know! My bad breath has me stumped, and I am in the middle of a process of elimination, I have already been to the dentist twice in the last 6 months, and my mouth is in great shape! The dentist told me that my bad breath must be related to my diet. I have elimnated dairy, sugar, etc, to no avail. I am desperate for an answer. Thank you so much!
