A gastroscopy is recommended for:

  • Upper abdominal pain

  • Chronic or new onset acid reflux and heartburn

  • Nausea

  • Difficulty swallowing (dysphagia)

  • Painful swallowing (odynophagia)

  • Barrett's Esophagus

  • Iron deficiency anemia

  • Helicobacter Pylori

  • Suspected Celiac Disease

  • Weight loss

  • Chronic diarrhea

  • Surveillance in individuals with an increased risk for stomach cancer, including individuals with a personal or family history of stomach polyps or cancer

More about the Gastroscopy Procedure 

Gastroscopy is typically performed when patients experience upper gastrointestinal symptoms and is the most effective procedure for the diagnosis of upper gastrointestinal tract cancer (esophagus, stomach and duodenum).

Gastroscopy is considered a very safe procedure with a very low risk of complications.

Your doctor will give you specific instructions to prepare for the procedure.

You should refrain from eating and drinking for 8 hours before the procedure, as an empty stomach is required.

In the endoscopy room, you will be asked to lie on your left side and the doctor will give you an intravenous sedative to make you feel more comfortable and relaxed during the procedure. 

After you have received the sedative, the doctor will gently insert a thin flexible tube called a gastroscope into your mouth and gradually guide it down your esophagus to your stomach and duodenum.

The tip of the gastroscope contains a tiny video camera that allows the doctor to see images of the inside of your upper gastrointestinal tract on a monitor in the endoscopy room.

The endoscope does not interfere with your breathing.

A gastroscopy is a screening, diagnostic and treatment tool.

When necessary, during the gastroscopy, minor surgical procedures such as a biopsy (taking a small tissue sample) and polyp removal can be performed.

The procedure takes about 15 minutes and should not be painful, but might be followed be mild discomfort (sore throat, bloating) that generally resolves within a day or two.

After the procedure, you will be transferred to the recovery room where you will be supervised for approximately one hour until the effects of the sedation wear off.


You will generally be discharged home about 1-2 hours after the examination.

The doctor will explain the results of your gastroscopy prior to discharge.

If a biopsy is taken, it will be sent to the laboratory for further testing.

Results are generally available within about a month and will be sent to you by the doctor.
