The fact that you have stomach pain after eating and feel full could be related to your gastritis
, so make sure you are taking something for it, such as ranitidine
for example. Your doctor should have checked for a bacteria in the stomach that can cause gastritis called Helicobacter Pylori
, for which you should be treated if its positive.
The fact that you get full quickly could also be related to delayed stomach emptying, this is called "gastroparesis" and there is a special radiology test for this.
The stone is probably unrelated to your symptoms, and just and incidental finding.
I advise you to eat small frequent meals, avoid fatty meals; do a trial of a diet without dairy products or lactose. Avoid pain medications such as ibuprofen
(or any NSAID). You need to follow up with your gastroenterologist for further recommendations.
