hello everybody!
since this helped me maybe it will help you too.
I have AF, 2 of them last time the doctor checked and I am a young person, no health problem, except stomach acidity.
It started 8 months ago after a I took antibiotics for a dental intervention.
I tried a lot of things for 4 months and nothing worked.
I then took ESPUMISAN, a medication used for stomach gas and acidity, which in my country is given without prescription and its main substance is called simeticona.
For me it worked, the next day everything was normal, as if I had nothing.
I repeated the experience since my acidity caused the AF to come back and everything was ok again.
So after 8-9 months now I have learned the following: it does come back, surgery is not an option for me, though it was recommended, acidity plays a key role, because the same way it attacks your stomach it can attack any other part and cause a tear, certain foods have to be avoided, only doctors can establish your real problem.
Hoping that my story will help and sorry if I used too many words.

Thanks or posting what helped for you!
