What is a Gastroscopy and How is it Performed?

A gastroscopy is a medical procedure that uses a flexible endoscope to examine the upper part of the digestive system. During the procedure, the patient is typically sedated and a numbing spray is applied to the back of the throat. The endoscope is then inserted through the mouth and advanced through the esophagus and into the stomach and duodenum. The endoscope has a light and a camera that allows the physician to examine the lining of the digestive system for any abnormalities.


Why is a Gastroscopy Needed?

There are several reasons why a gastroscopy may be needed. Some of the most common reasons include:

  • Unexplained abdominal pain or discomfort
  • Difficulty swallowing
  • Persistent heartburn or acid reflux
  • Unexplained weight loss
  • Persistent vomiting
  • Blood in vomit or stools
  • Screening for cancer or precancerous conditions

How to Prepare for a Gastroscopy?

It is important to prepare for a gastroscopy to ensure that the procedure goes smoothly and safely. The preparation process typically involves fasting for several hours prior to the procedure, as well as abstaining from certain medications. Your physician will provide you with specific instructions on how to prepare for the procedure.

During the procedure, you will be sedated and a numbing spray will be applied to the back of your throat. You will be asked to lie on your side, and the endoscope will be inserted through your mouth and advanced through the esophagus, stomach, and duodenum. The procedure typically takes 15-30 minutes to complete.

Like any medical procedure, there are risks and complications associated with gastroscopy. Some of the most common risks include bleeding, infection, perforation, and adverse reactions to sedation. However, the risk of these complications is relatively low, and your physician will take steps to minimize these risks.

It is important to seek medical attention if you experience any severe pain, persistent bleeding, or difficulty swallowing after the procedure. These symptoms may indicate a complication and should be evaluated by a physician.
