I have this problem for almost 3 years now. I think is high histamine in our bodies is causing this problem.
Since I have consume antibiotics I notice this problem. I think my body is reacting to something in my body that give some people allergic reaction. Because not everybody will react.
I also notice when I eat fruits my stomach been to makes noise, that provoke me to have gas and I can hold it in I will pass gas. I have mild bad breath.If I eat sugar animals product it makes my breath fill the whole room.
Since I eat Low FODMAP diet without animals product I stop pass uncontroble gas without, but I still have alot of gas.
Since 1 week I'm taking vitamine C 3000 mg a day to control my Histamine.
I think that people who react on me are sensitive to histamine that my body is making. I don't know.
