Hi Wiix,
I am very sorry for your discomfort.
Did your GI specialist or your GP/Family doctor treat you for gastritis after your endoscopy?
Can you think of anything that may be irritating your stomach?
I have to take most of my meds with food or I get gastritis, for instance.
I cannot prescribe a regimen of meds, even OTC. Please contact your physician, as there may be a reason you continue to experience gastritis and your doctors may need to rule out other issues, including pathogens which may cause ulcerations, etc. It's important your treating physician know the gastritis has continued for you.
Please let us know how you are doing?
Warmly,
DejaVu
