Thanks for the tag @lisalucier
If I have this correct, @emlozano01 you had an upper endoscopy then your doctor prescribed omeprazole to help your inflamed stomach, diarrhea and unintended weight loss.

I feel your pain and am familiar with your symptoms. Unfortunately, it probably will take time to let the medication work.

It sounds like you have been taking this new medication for a couple weeks now and it has not solved your problems. I am not surprised. I started a proton pump inhibitor (PPI) 6 months ago, checking in with my doctor at 3 months and was able to drop my dosage. My symptoms similar to yours have been improving but certainly not the first 2 weeks I took the drug. In addition to the drug I eat food my body likes and exercise every day to keep my GI working. I try to do everything I can to help the medicine work as quickly as possible.

- You mention calling your doctor to discuss your issues. Have you yet, and if not will you come back and comment as to how you are doing?
- How long have been struggling before getting your endoscopy?
- Have you noticed any change at all in the frequency of your symptoms, or perhaps new ones since starting your new medication, has it changed anything, for the worse or the better?
