Upper endoscopy, also known as esophagogastroduodenoscopy (EGD), is a procedure that allows doctors to examine the lining of the upper part of the gastrointestinal tract, including the esophagus, stomach, and duodenum.
An upper endoscopy, also known as esophagogastroduodenoscopy (EGD), is a minimally invasive diagnostic procedure that allows your doctor to examine the upper part of your gastrointestinal (GI) tract, including the:
Esophagus
Stomach
Duodenum (the first part of the small intestine)
This procedure is performed using a thin, flexible tube called an endoscope, which has a light and high-definition camera at its tip. The camera transmits live images to a monitor, allowing your specialist to detect abnormalities with precision.
An upper endoscopy helps diagnose and sometimes treat a wide range of digestive disorders, such as:
Chronic heartburn or GERD (gastroesophageal reflux disease)
Stomach ulcers or bleeding
Difficulty swallowing (dysphagia)
Unexplained nausea or vomiting
Persistent upper abdominal pain
Suspected stomach cancer or esophageal cancer
Celiac disease or inflammation
If necessary, tissue samples (biopsies) can be taken during the procedure for laboratory analysis.
To ensure clear visibility during the exam, you will be asked to fast for 6 to 8 hours before the procedure. Your doctor will also advise if any medications need to be paused temporarily.
Preparation steps include:
Avoiding all food and drinks the night before
Informing your doctor about blood thinners or diabetes medications
Arranging for someone to accompany you home after the procedure (if sedation is used)
You’ll be given a sedative or local anesthesia to minimize discomfort.
The endoscope will be inserted gently through your mouth and guided down the esophagus into the stomach and duodenum.
Air may be introduced to expand the stomach lining for better visibility.
If necessary, tools may be used through the scope for biopsies or to stop bleeding.
The procedure is safe, generally painless, and takes 15–30 minutes.
Recovery is usually quick. After the procedure:
You’ll rest until the sedative wears off
You may experience a mild sore throat or bloating (from introduced air)
You can usually eat and return to normal activities the next day
Your specialist will review the findings with you and advise on next steps or treatments if needed.
Upper endoscopy is considered a low-risk procedure when performed by experienced gastroenterologists. Possible complications (rare) include:
Minor throat irritation
Bleeding (especially if biopsy or polyp removal is done)
Reaction to sedative
Perforation (extremely rare)
We use advanced, sterilized equipment and international safety protocols to ensure your procedure is as smooth and safe as possible.
