Thanks for providing more information.
I understand your worry.
Firstly it's good that proton pump inhibitors are working for your symptoms.
Endoscopy was performed as a precautionary measure to determine the exact diagnosis of pain in stomach,heartburn,nausea,loss of appetite.
Although your doctor is likely to suspect gastritis after talking to you about your medical history and performing a thorough exam, however you may also have tests to pinpoint the exact cause.
As H.pylori and Barrett's esophagus can also result in GERD symptoms.
And treatment depends on the underlying pathology.
So you shouldn't worry about endoscopy results as they are fine.
Gastritis is inflammation of stomach mucosal lining resulting in burning ache or pain (indigestion) in your upper abdomen that may become either worse or better with eating,nausea,vomiting,a feeling of fullness in your upper abdomen after eating.
As you have loss of appetite,you should hydrate yourself with plenty of water.
And eat small frequent meals instead of large meals.
Avoid late night meals.
And consult your doctor for a clinical corelation of your endoscopy results with your current symptoms.
Hope this helps.
