Wlcome to HCM
After gonig through medical history of your wife , she has Hypertension
,Diebetes,IHD,Anaemia(Blood loss),GERD along with H.Pylori and a Kidney
It seems that as she had stomach problem and due to aspirin
she lost bllod and became anaemic,but now she is not taking aspirin,and your query is regarding H.Pylori, In this regard alog with PPI triple or quadruple therapy is given and most of the time is successful but relapse may occur.
Ihope her diabetes
and BP are controlled and she should take iron suppliments for 6 months, and keep her Hb to normal level
Good luck to her
