Yah trust me I have been asking myself the same questions, I still think it could be bacteria or pathogens in my stomach. Basically my stomach looks extremly health and my intestinal health is superb, the only wierd thing is that I have suffered from bo since middle school probably and my stomach is a little bit inflimated and he said it was gastritis. But basically he made it sound like no big deal Ill keep you guys updated on what else he tells me when I go back to see him next week
