Hi, Glad I found this website. My age is 30 years and I am facing serious bad breath problem which is affecting in personal/profession life. Let me give you brief idea about my symptoms. 1. I am having bad breath from long time. I visited dentist few times and no help. I guess they are not able to understand exact problem and try to clean teeth’s every time. 2. The bad breath is severe when I have dry mouth , no talking/speaking with anyone while watching TV, enclosed areas (like car, meeting rooms etc.) 3. I feel nausea/vomiting during dentist visits when they ask to open my mouth for few minutes. But in few seconds I feel nausea. 4. From last two/three months, I get yellow tongue when I get up in the morning. 5. I have abnormal stools (sometimes colored stools) and sometimes anus burning. Most of times, my wife complain about bad smell after my stools. I don’t have any problem with my weight which is consistent 140 lbs from years. After reading various topics on Internet, I am now little worried whether I have some disease. Thanks, Sandy
