dravstvujte the dear doctor. I since the childhood with friends, gde-that about 14 years, we plaid about. Know, it is simple so eructations did or made, etc. Mum gvoorila to me to not do or make, but potmo I have got used... Then I have ceased. And now suddenly she all time is done or made. That is in one day has suddenly begun so. I swallow, and there kak-that is unpleasant, as though something is inflated or fanned. And then eructations as though leaves. It is not lethal? I very much experience. It not a ulcer? It is treated?

Simply you swallow air together with nutrition. It is not terrible, and it is not treated.
