Upper Endoscopy (EGD): The Questions Patients Actually Ask — Answered by Physicians
Upper Endoscopy (EGD) generates some of the most repetitive phone calls in any gastroenterology practice: fasting windows, medication timing, and what the sedation will feel like. PrepQ, a patient-education platform built by physicians and operated by PrepQ LLC, maintains 13 physician-written answers about upper endoscopy (egd) as part of a library of more than 7,500 answers covering 700-plus procedures across 14 specialties. Practices that subscribe to PrepQ give their patients a dedicated phone number to text or call at any hour, and the platform replies instantly with content the practice's own clinicians have reviewed and approved in advance. Questions outside the approved library are referred back to the office, and any message that suggests urgent symptoms is directed to 911 or the practice instead of being answered by software. The result: patients arrive prepared, day-of cancellations drop, and staff stop repeating the same upper endoscopy (egd) instructions dozens of times a week.
Real upper endoscopy (egd) questions from our physician-reviewed library
A sample of the 13 upper endoscopy (egd) answers in PrepQ's library. Before any practice goes live, its own clinicians review and approve every answer — and can customize each one to their protocols.
Can I eat right after the upper endoscopy?
After an upper endoscopy, you usually wait until you are fully awake and any throat numbing has worn off before eating or drinking, often about an hour or two, to avoid choking. Many people start with sips of liquid and soft foods, then return to a normal diet as tolerated. Follow the specific eating instructions your care team gives you.
Can I take my morning pills with a sip of water before the EGD?
Many people are told to take important morning pills, such as blood pressure or heart medicines, with a small sip of water before an EGD, while holding others like diabetes medicines or blood thinners. Because it depends on the drug, do not decide on your own. Ask the doctor's office for a clear list of which medicines to take and which to hold.
Do I need a driver after an EGD too?
Yes, if you have sedation for an EGD, which is common, you will need a responsible adult to drive you home and you cannot drive, take a rideshare, or go alone for the rest of the day. If you have only a numbing throat spray with no sedation, a driver may not be required. Confirm your facility's specific rules ahead of time.
How long do I have to fast before an upper endoscopy?
You usually need to fast before an upper endoscopy so your stomach is empty for safety and a clear view, commonly no solid food for about six to eight hours and stopping clear liquids a couple of hours before, often two. The exact times vary by facility, so follow the specific instructions you are given and confirm with the office if unsure.
How long does an upper endoscopy actually take?
The upper endoscopy itself is usually quick, often taking about 5 to 15 minutes, though it can be a bit longer if biopsies or treatments are done. With check-in, sedation, and recovery, plan to be at the facility for a couple of hours overall. Ask your team for an estimate based on your situation.
I'm on Ozempic/semaglutide — do I need to stop it before the endoscopy?
Ozempic and other GLP-1 drugs slow stomach emptying, which can raise the risk of food in the stomach during sedation for an endoscopy. Guidance is moving toward a case-by-case plan, sometimes a longer clear-liquid diet beforehand rather than always stopping the drug. Do not change your dose on your own. Ask the prescribing doctor and the procedure team for instructions specific to you.
Is it normal to feel bloated or burp a lot after the endoscopy from the air?
Yes, feeling bloated or burping a lot after an upper endoscopy is normal because air is put into your stomach to help the doctor see, and it usually passes within a few hours as you release the gas. Walking and gentle movement help. Call your doctor if you have severe or worsening belly or chest pain, trouble breathing, vomiting blood, or fever.
My doctor wants to do an upper endoscopy — what is that and what will it find?
An upper endoscopy, or EGD, uses a thin, flexible camera passed through your mouth to look at your esophagus, stomach, and the first part of the small intestine. It can find causes of problems like heartburn, swallowing trouble, pain, bleeding, or ulcers, and the doctor can take biopsies or treat some issues during the exam. Ask your doctor what they are specifically looking for in your case.
Should I hold my diabetes medicine before the endoscopy since I can't eat?
Yes, diabetes medicines often need to be adjusted or held before an endoscopy because you cannot eat, which can lower your blood sugar. The right plan depends on your specific medicines and your numbers. Do not change them on your own. Ask the prescribing doctor or the office how to handle your diabetes medicines, and check your blood sugar more often that day.
What are the risks of an upper endoscopy — can it tear my esophagus?
Upper endoscopy is very safe, and serious problems are rare. A tear in the esophagus, called a perforation, can happen but is uncommon, and bleeding or a reaction to sedation are also rare. The team is trained to prevent and manage these. After the procedure, emergency care may be needed for severe chest or belly pain, trouble swallowing or breathing, vomiting blood, or fever.
