Thanks for your query.
Noted the history and understood your concerns.
With the detailed history of H pylori, its treatment for 2 weeks, Ursodiol for gall stones
which were not seen on consecutive ultrasound
, development of bloating and acid reflux
in spite of probiotics on and off and daily yogurt indicate the need of further evaluation:
I would advise you the following in such a situation:
Get an upper GI Endoscopy examination.
Barium swallow and follow through.
Tests of stool on three consecutive days.
Tests of blood: CBC, liver and other functions as may be needed.
Clinical evaluation by a Gastroenterologist to see for probable clinical diagnosis to be supported and finalized by reports of investigations so that a proper management can be done.
If the stool tests shows sort of infection then a course of an antibiotic, metronidazole
Change the probiotics.
It is also possible that stress and anxiety are playing their parts causing aerophagia
and thus causing gases and bloating, hence get a control over these if you have any.
