If you're scheduled for an upper endoscopy (EGD) or considering one, you likely have dozens of questions about what to expect, how to prepare, and whether it's the right procedure for you. Understanding the details upfront helps you feel confident and avoid last-minute stress on procedure day.
What Is an EGD and When Do You Need One?
An esophagogastroduodenoscopy (EGD) is a diagnostic and therapeutic procedure where a gastroenterologist uses a thin, flexible camera to examine your esophagus, stomach, and the first part of your small intestine. Common reasons for referral include persistent heartburn, difficulty swallowing, unexplained abdominal pain, suspected ulcers, Barrett's esophagus screening, or bleeding in the upper digestive tract.
The procedure typically takes 15–30 minutes depending on what your doctor finds and whether any treatment (like biopsy or polyp removal) is needed. It's considered safe, with serious complications occurring in fewer than 1% of cases.
How Should You Prepare for an Upper Endoscopy?
Proper preparation is critical for a successful procedure. You'll need to fast completely—no food, drinks, or even water—for 6–8 hours before your appointment. Many providers send written instructions 1–2 weeks ahead; follow them exactly.
Key prep steps:
- Stop aspirin, clopidogrel, and certain other blood thinners 3–7 days prior (ask your doctor specifically about your medications)
- Arrange transportation, since sedation means you cannot drive for at least 24 hours
- Wear comfortable, loose clothing
- Remove dentures and contact lenses before the procedure
- Plan to have someone pick you up and stay with you at home afterward
Some facilities ask you to arrive 30–45 minutes early for paperwork and vital signs. Confirm timing and location when you receive your pre-procedure call.
What Type of Sedation Will You Receive?
Most upper endoscopies in the U.S. use conscious sedation (sometimes called twilight sedation), where you receive mild sedatives through an IV to help you relax while remaining somewhat responsive. Your throat will also be numbed with spray anesthetic.
A few patients opt for no sedation at all, though this is rare and significantly less comfortable. General anesthesia is typically reserved for complex cases or patients with anxiety or special medical needs. The type and depth of sedation should be discussed with your gastroenterologist during your consultation—bring up any concerns about anesthesia side effects or past experiences.
Sedation costs vary; expect to budget $300–$800 for anesthesia on top of the base procedure fee.
What Are the Realistic Costs?
An upper endoscopy typically ranges from $1,500 to $4,000 without insurance, depending on your location, facility type (hospital vs. outpatient center), and whether biopsies or treatments are performed. Insurance coverage varies widely; verify your exact out-of-pocket responsibility before your procedure.
Ask your provider's billing department:
- The base procedure cost
- Anesthesia and facility fees
- Whether biopsies or therapeutic interventions carry extra charges
- Your deductible and coinsurance percentage
- If they offer payment plans for uninsured or underinsured patients
Many gastroenterology centers offer transparent pricing upfront, so don't hesitate to shop around and compare estimates.
What Happens After the Procedure?
You'll spend 30–60 minutes in recovery while the sedation wears off. Your throat may feel slightly sore, and you might have mild bloating or belching as air used during the procedure exits your system. This typically resolves within a few hours.
You can usually resume a light diet the same day—start with clear liquids or soft foods and progress as tolerated. Avoid alcohol and strenuous activity for 24 hours.
Your doctor will review findings with you before discharge, but detailed results (including pathology from biopsies, if taken) may take 3–5 business days. Follow-up instructions depend on findings; some patients need medication adjustments or repeat procedures, while others require no further action.
How Do You Choose a Qualified Gastroenterologist?
Look for board certification in gastroenterology and experience with the specific concerns driving your procedure. Ask about the facility's accreditation (Joint Commission or AAAHC are gold standards) and complication rates.

Frequently Asked Questions
Q: Can you eat or drink anything before an upper endoscopy? No—you must fast for 6–8 hours, with no food, beverages, or water allowed. Even small amounts of liquid can obscure the doctor's view and may require rescheduling.
Q: What's the difference between an upper endoscopy and a colonoscopy? An upper endoscopy (EGD) examines your esophagus, stomach, and duodenum, while a colonoscopy examines your colon and rectum; both use a camera-equipped tube but target different digestive areas.
Q: Will you feel pain during the procedure? With sedation and topical numbing, you should feel pressure or mild discomfort but not significant pain. If pain occurs, alert your medical team immediately.
