hello and thanks for query
as u have said in ur history u had been diagnosed with h.pylori one year back it is highly unlikely that u have persistent h.pylori infection since u have been taking antibiotic for over a year. it is very important to analyse ur symptoms properly since u may be having some other inflammatory or irritable bowel syndrome
. cure of h.pylori can be confirmed by urea breath test
or by histopath diagnosis . I suggest u consult a gastroenterologist
to get a endoscopy
to get u a diagnose accurately ur problem. plz do not take any antibiotic over the counter since any drug taken for such a long time will definitely have side effects, besides the organism may develop resistance and will be difficult to eradicate. don't worry ur problem can definitely be solved. hopefully this will solve ur query .
thanks. good luck .
