hello there..thank you for your query . She must be suffering from H.pylori associated gastritis for which she has been treated and i assume she has taken full course of treatment.If still she is suffering from the heart burn than first you should look for her eating habbits.she should not take spicy meal,fermented food products.Also avoid being empty stomach as much as possible.She can also take pantoprazole empty stomach or as prescribed by the physician.you should visit your doctor. thank you..i hope it was helpful
