Hi, I have a severe bad breath issue despite of brushing my teeth twice a day. After brushing my teeth also, in 10-15 mins, bad breath occurs throughout day. I visited 2-3 dentists during a course of 3-4 years and all of them confirmed that bad breath is not due to my mouth. They asked me to visit a ENT and gastroenterology doctor. So I visited ENT doc and he said all is good. Now I wish to know a gastroenterologist who can identify the actual cause and treat me completely. Well, I am just 36 and while talking to people, I get embarassed and feel less confident. Can some gastroenterologist please help and guide me genuinely? I reside in Pune.
