What Is A Gastroscopy?


Gastroscopy (also known as Endoscopy) is a procedure which allows your doctor to look directly at your upper gastrointestinal tract. In this exam, a fiberoptic tube is inserted through your mouth and into your swallowing tube (esophagus), stomach, and first part of your small bowel (duodenum). Discomfort is usually minimal. You will be given a drug to help you sleep (sedative) during your procedure. This exam helps to detect problems with swallowing tube (such as acid reflux or inflammation), inflammation or ulcers in your stomach or small bowel, tumors (cancer), and any other abnormalities. Small pieces of tissue are usually taken from the stomach (biopsy) and examined in the lab under the microscope to check for bacteria that can cause inflammation or ulcers (Helicobacter Pylori).

Before The Procedure:


  • Have a light dinner on the evening before your exam

  • Have nothing to eat or drink after midnight before your exam


After The Procedure:


  • Even though you did not have a general anesthetic, you have received sedation. Get plenty of rest for 24 hours after your examination. You may experience some cramping, gas, or bloating due to air. Burping may also occur for a few days

  • You may have a slight sore throat or hoarseness for a day or two. This is normal. You may gargle with warm salt water as necessary

  • You may resume normal eating following discharge

  • You must NOT drive on the day of the procedure. Please arrange for someone to drive you home after the exam

  • Follow your doctor’s specific instructions concerning treatment and follow-up care. Contact us if you have any questions


For 24 hours after the examination Do Not:


  • Drive a motor vehicle

  • Operate machinery

  • Drink alcohol
