Gastritis Disorder

Hello!
My name is amichay and I am 22 y.O.

Usually I am healthy..
Three months ago I did the exam of "gastroscopiea" and the doctor found out I have "hard antrom gastritis in my stomach.
Its have been allmost a year since I felt the disorder in my system.

I was given a prespriction for losec and instructions to take 2 pills per day for a month.

I took the medication for only 1 week and stopped.
Then after many things and ways I have tried I understood why I should take losec and started to take it again but I feel that is not enough.
Ofcourse I know I cant be healed in instant but still something is missing..

What I want to ask you is what steps I should follow to get better in your experience ?

Do I need to change my lifestyle,attitude? Take medications
practice sports,eat particular things..And sort?

What do you suggest?

Thank you :wink:
amichay, il
