Quick Answer: What should I expect from an upper endoscopy (EGD)?
You can expect fasting instructions before the procedure, sedation or anesthesia support during the exam, a short recovery period afterward, and follow-up guidance based on findings such as reflux-related inflammation, ulcers, infection, or biopsy results from the esophagus, stomach, or duodenum.

Questions to review before the procedure
| Step | What usually happens | Why it matters |
|---|---|---|
| Before the procedure | Fasting instructions, medication review, health-history review, arrival time, and transportation planning are confirmed. | This helps reduce delays and supports safe sedation planning. |
| Procedure day | Check-in, consent, sedation support, and upper digestive tract evaluation are completed by the care team. | The gastroenterologist examines the esophagus, stomach, and duodenum. |
| During the exam | The doctor may look for inflammation, narrowing, ulcers, bleeding, infection, or abnormal tissue changes. | Biopsies may be taken when lab review is needed. |
| After the procedure | You recover from sedation, receive discharge instructions, and learn how findings or biopsy results will be reviewed. | Most patients need a responsible adult driver after sedation. |

Frequently Asked Questions About Upper Endoscopy (EGD)
What is upper endoscopy used to evaluate?
Upper endoscopy evaluates the esophagus, stomach, and first part of the small intestine when symptoms or test results suggest an upper digestive problem.
What symptoms may lead to EGD?
Persistent reflux, trouble swallowing, food sticking, vomiting, unexplained anemia, black stools, upper abdominal pain, or suspected ulcer disease may lead to EGD planning.
What happens during the procedure?
A thin flexible scope is passed through the mouth while sedation is commonly used. The doctor looks for inflammation, narrowing, ulcers, bleeding, or other findings.
Why are biopsies sometimes taken?
Biopsies can help check for inflammation, infection, celiac disease, Barrett’s esophagus, or other tissue-level changes that cannot be confirmed by appearance alone.
How should I prepare for EGD?
You will receive fasting instructions, medication guidance, arrival details, and transportation rules before the procedure.
What happens after EGD results are available?
Your care team reviews findings, biopsy results if taken, medication changes, follow-up testing, or treatment planning based on the results.
