What is an EGD?

EGD, also known as upper endoscopy, is a procedure used to examine the esophagus, stomach, and upper part of the small intestine (duodenum). Dr. Patel will insert a flexible tube with a camera (endoscope) through the mouth to visualize the upper gastrointestinal tract.

Why would I need this?

This procedure can be used to discover the source of symptoms like abdominal or chest pain, nausea and vomiting, heartburn, bleeding, difficulty or inability to swallow.

EGD is used to diagnose various conditions, including gastroesophageal reflux disease (GERD), ulcers, gastritis, tumors, celiac disease, hiatal hernias, strictures, etc. It can also help in obtaining biopsies and treating certain conditions.

What should I prepare for the procedure?

Fast before the Upper endoscopy or EGD

You'll typically need to stop eating solid food for eight hours and stop drinking liquids for four hours before your endoscopy. This is to ensure your stomach is empty for the procedure.

Stop taking Blood thinners

You'll need to stop taking certain blood-thinning medications in the days before your EGD, if possible. Blood thinners may increase your risk of bleeding if certain procedures are performed during the endoscopy. If you have ongoing conditions, such as diabetes, heart disease, or high blood pressure, Dr. Patel or her Medical assistants will give you specific instructions regarding your medications.

Continue all medications before the exam unless otherwise directed by Dr. Patel.

You will be sedated during your endoscopy. Because of this you will not be able to drive after the procedure and will need to arrange for someone to drive you home.

What happens during EGD?

During an EGD, you will receive sedation to ensure comfort. Doctor Patel will gently pass the endoscope through your mouth and into your esophagus, stomach, and duodenum while monitoring the images on a screen. The procedure usually lasts from 10-15 minutes. For most patients, the procedure is not uncomfortable and many will sleep through the procedure.

What happens after the procedure?

After the EGD, you may experience a sore throat or bloating due to the air introduced during the procedure. You will need someone to accompany you home, as sedation may impair your judgment and reflexes temporarily. Doctor Patel will discuss the findings and any necessary follow-up care. Unless Dr. Patel instructed you differently, you’ll be able to resume your normal diet and medication schedule after you go back home. Complications after EGD are uncommon. Should you experience fever, chills, chest pains, persistent sore throat, abdominal pain or notice a significant amount of blood in your stool, contact our office immediately at 949-298-7112 and go to your nearest emergency room.
