Recently had an endoscopy and was diagnosed with gastritis. I've been having stomach issues and I was already aware of this and was hoping they would be able to tell me more than just telling me I had a stomach inflammation. Anyway doctor recommended I take an Antacid (Nexium or Omeprazole 40 **) for 3 months straight. I've already taken Omeprazole for a month at a time a few times in the past and I'm not sure if I wanna take it for that long as I have heard its not good for you long term as I am still fairly young. Any advices?
