Hi Doctor, I Am Suffering From Severe Acidity Problem. Changed

Hi Doctor,

I am suffering from severe acidity problem. Changed diet multiple times and still acidity is not under control.
2 months back I was diagnosed for duodenal ulcer and advised anti-biotics and nexium(Esmoprazole) 20 mg twice a day.

Even after taking tablets, the acidity not controlled. I have completely stopped spice food, taking less oil and only food with bit salt . Taking fruits like Apple, pear, banana and some times kiwi fruit.
Taking lot of vegetables also.

Please help me on how to control my diet and what foods to include and what not to take.
Also, please let me know what should be taken to control the acidity when it is severe.

Regards,
Madhusudan K
