Gastritis caused by bile reflux: how to cure, what to eat

Hi, I’ve (19F) had some abdominal discomfort for almost 5 years now and only recently got diagnosed with gastritis caused by bile reflux.

My doctor has already prescribed me Ursobil, esomeprazole and Levosulpride. The first one I have to take for a couple of months, while the others just for a couple of weeks.

Now my biggest concerns are: -how long they’re going to take in order to be effective -what kind of dietary changes I need to adapt for the next months

I’ve already taken the pills for a couple of days, and nothing has changed just yet, but I think that’s quite normal. I’m mostly anxious about the fact that they’re not going to work. I’ve already had 3 other different therapies but they were always ineffective, so it really got me anxious.

Technically the diagnosis should be correct right now since I’ve done an endoscopy, but I’m not 100% sure.

Had anykne else had a similar experience/is currently going through the same thing? Could you give me some advices in order to get better?

Thank you :3.
