Gastroscopy is a diagnostic procedure used to examine the upper gastrointestinal tract, allowing the doctor to assess the condition of the oesophagus, stomach, the duodenal bulb, and the descending part of the duodenum.

The procedure involves inserting a gastroscope, a flexible tube equipped with a light source and forceps, into the oesophagus. The forceps enable the collection of tissue samples for histopathological examination if necessary. Gastroscopy allows the doctor to visualise and record images from inside the patient’s body.

The procedure typically lasts between 10 and 30 minutes. Prior to the examination, the patient’s throat is numbed with a local anaesthetic, or the procedure is performed under general anaesthesia with the assistance of an anaesthetist, making it more comfortable for the patient. After the gastroscopy, it is advised to avoid eating and drinking for a certain period of time, as the irritated throat and oesophagus may cause discomfort. Following the procedure, patients may experience bloating or belching due to the introduction of air into the digestive tract. These symptoms are usually short-lived and resolve naturally.

The results of the examination are typically available within about two weeks, although the result for Helicobacter pylori is known within minutes of completing the procedure.

Indications

The procedure is recommended for patients experiencing symptoms suggestive of upper gastrointestinal tract disorders, such as: 

  • Frequent heartburn
  • Symptoms of gastro-oesophageal reflux, including difficulty swallowing or the sensation of a foreign body in the oesophagus 
  • Epigastric pain 
  • Nausea and vomiting 
  • Unexplained weight loss 
  • Anaemia
  • Belching or a feeling of fullness, particularly after meals 
  • Bleeding from the upper gastrointestinal tract (e.g., vomiting blood) 
  • Symptoms related to the lower gastrointestinal tract, such as tarry stools or a positive faecal occult blood test 

Benefits

Accurate Diagnosis

Enables direct visual assessment of the upper digestive tract.

Early Detection

Helps identify gastrointestinal conditions at an early stage.

Tissue Sampling

Allows biopsies for histopathological analysis.

Quick Procedure

Usually completed within 10–30 minutes.

How to Prepare

Preparation for the procedure includes the following steps:

  • Patients should arrive on an empty stomach. If the gastroscopy is scheduled for later in the day, they should refrain from eating for at least 6 hours and from drinking for 4 hours before the examination. 
  • Smoking, chewing gum, or sucking sweets should be avoided before the procedure. 
  • Patients who take regular medication should continue to do so at their usual time, with a small amount of water. 
  • For patients taking blood-thinning medications, the dosing regimen should be discussed with the doctor performing the procedure.
