Gastric erosion, las lex, esophagatis.

I have acidity and gerd problem from last 2.5years. that times I did endroscopy and only hiatal hernia was found I took ppi for 2mknth and prblm was reduced. In mean time I got pregnant and lead restricted lyf style. Acidity happened that time and took zontac when required. After 1year of delivery I starts to feel upper abdomen pain often after food, acidity , burning sensation etc. I visited doc and she did endroscopy and result is body and antrum multiple errosion, esophagatis grade A , Lax LES..RUT negative found.  she gave me med. My question is 1.how long it will take to recover? 2.will it permanently curable? 3. Will it become  recurring problem? 4. Within 1year erosion how could be happen? I'm maintain healthy lifestyle.
