I have a really strong odour that comes from my mouth. It always has different smells like poo or somthing dead. ive been to the doctors dentists.  Had a gastrophase been tested for so many things.  When cars drive past there heads turn like they smelt me. Everywhere i go people cough around me like they gag. I dont no what to do and i hate to say it but im close to giving up. Every second of every day is uncomfterble. It started when I was about 18 and slowly got worse and worse and im 21 now
Hi in regard to your query, you have mentioned that you had visited doctors and dentists, but you have not mentioned what did they say. Basically bad odor from mouth is of many reasons either because of poor oral hygiene or any systemic diseases like diabetes, liver insufficiency, kidney diseases etc... since you have mentioned something like dead I would suggest you check your diabetic status since you are healthy with your gastric status. I would suggest you to undergo complete health check up with your systemic status and make sure you are healthy and go for dental check UPP to confirm that your oral health is good too. Hope this is helpful. Without treating the systemic cause treating the only oral causes will not help. Hope this is helpful.
