Yes. It may show signs of inflammation caused by the acid reflux (oesophagitis or stomach for example). A normal upper endoscopy doesn't exclude acid reflux it just indicates that there are no associated serious complications or underlying conditions causing or perpetuating it. For specific advice on whether the test is right for you, you could discuss further with the doctor who ordered it.
Endoscopy. Yes it really can. You can see irritation and even see the stomach acid come up.
I have a question about Prilosec and a upper endoscopy. If I take Prilosec and it stops my acid reflux, would I need to have a upper endoscopy since it might show no acid reflux damage. Other tests?

If your reflux has been long standing and you also have abdominal pain an endoscopy study is warranted to rule out tissue changes in your lower esophagus and to be sure you are not dealing with a cancer problem. Prilosec (omperazole) is a very good medication but it may also be covering up more than reflux discomfort. Read more...
