What could they find wrong with me when doing an edg?

Depends: It all depends on the presentation of your symptoms and illness. An EGD is usually recommended for further diagnosis and treatment of upper GI diseases. Please ask your GI doctor on what can be found for further guidance.

EGD: I believe you meant to ask about EGD (esophagogastroduodenoscopy), a/k/a upper endoscopy. It is usually done in the setting of persistent nausea. vomiting, heartburn of unclear etiology or when upper gastrointestinal bleeding or stomach malignancy is suspected. Usually mucosal biopsy will be done during the procedure for tissue diagnosis.
