Has anyone seen a gastro doc for this problem? You could be having stomach or digestive problems...just a thought. I have gotten all my teeth pulled and I have that issue off and on, but I also have blisters, cold sores, and thrush alot so I have other problems besides that. I would try a gastro doc and see what they say. Has your primary recommended anyone?

Hello
I suffer from fecal breath that can fill up room... Everything sttarted 5 years ago when I had UTI infection. I had urgent will to piss and even when I pissed I had feeling of not emptying my bladder. Visited urologist who did US of my bladder and prescribed me 3 antibiotics for 14 days. At 10th day I nothing changed so I was looking at forums and someone posted that I should've done urine culture test. I did it and they found e.coli. Went to another Doc and he prescribed me another 2 antibiotics. At 2nd day I felt relief and thought everything will be fine. 2 weeks after course of 2 antibiotics I started smelling sh*t, didn't know at that time it was from me. Everyone started to talk behind my back and I realized i have problem. So far I did colonoscopy with sample, 2xgastroscopies with sample, diabetes blood test, full blood count tests, SIBO , stool culture, clostridium difficile test, MR of m booty area, swabs tests from nose,ear,throat, mineral levels blood test, CT of sinuses, curved septum surgery, I tried probiotics(they make it worse even.....), US of my belly. I eat only lean meat, rice and veggies such as carrot ( no beans,tomatoes etc), Visited also 5GI's DOc's ( they prescribed me PPI's without result)

Hi @noble77. You mention having the same bad breath problems as @laceys63, struggling to figure out if something in maybe your GI is causing it. It is frustrating to keep trying mouthwashes that work for a time but then you have to switch and try another one. I am hopeful you will find help you need as you keep trying to figure out what is going on, perhaps a connection elsewhere like your gut.

I did just listen to a podcast Mayo Clinic’s “On Nutrition” put out that you may find helpful. I learned a lot about my mouth, how it’s connected with my general health, and even where medical professionals are in terms of understanding it all (or not). You will want to scroll down to find the episode:
- “Whole-Body Care, Starting With a Smile” (01/16/2026) https://mcpress.mayoclinic.org/podcasts/on-nutrition/

I would love to hear what you think about the information shared on the podcast.

Do you think you will look for a dentist and/or primary care doctor willing to help you?

There may be some insight here.
