Are Your Symptoms Affecting Your Quality Of Life?
You may need a gastroscopy. Consult our gastroscopy specialist today for a detailed consultation & personalised treatment plan.
Gastroscopy, also known as upper endoscopy, is a medical procedure in which the doctor examines the upper part of the digestive system. This includes the oesophagus (the tube that transports food from the mouth to the stomach), the stomach, and the beginning of the small intestine (duodenum).
The procedure uses a thin, flexible tube called an endoscope with a light and a camera attached to it. Gastroscopy is primarily used to diagnose and sometimes treat conditions like ulcers, inflammation, tumours, and bleeding in the upper digestive tract.
Gastroscopy is recommended for several reasons. Common indications for undergoing the procedure include:
Chronic or unexplained abdominal pain can indicate a variety of gastrointestinal issues. Gastroscopy can help identify the underlying cause, such as ulcers, inflammation, or other abnormalities.
This may indicate an oesophageal blockage or constriction. Gastroscopy allows the doctor to view inside the oesophagus and identify any growths, strictures, or obstructions.
Persistent nausea and vomiting can be symptoms of underlying gastrointestinal conditions.
Continuous bloating and a sense of fullness might indicate gastroparesis or blockages in the digestive tract.
Frequent heartburn and acid reflux can be signs of gastro-oesophageal reflux disease (GERD) or other esophageal conditions.
Gastroscopy provides several advantages for diagnosing and treating upper digestive system conditions, including:
It can identify oesophagitis, gastritis, and peptic ulcers early, allowing for prompt treatment that can prevent complications and improve outcomes.
It provides a direct view of the oesophagus, stomach, and duodenum, allowing for the precise identification of ulcers, inflammation, tumours, and sources of bleeding, which aids in developing an effective treatment plan.
It enables the collection of biopsy samples from the digestive tract lining. These samples are examined under a microscope to diagnose infections, inflammation, or cancer, confirming non-visual diagnoses.
It allows for treatments such as polyp removal, bleeding control, widening narrow areas, and foreign object extraction during the procedure.
Proper preparation for gastroscopy helps ensure accurate results and a smooth procedure, which includes:
Fasting: Patients are usually required to fast for 6 to 8 hours before the procedure, abstaining from all food and drink to ensure an empty stomach, to improve visibility and to reduce discomfort during the procedure.
Medication Adjustments: Some medications, particularly blood thinners and diabetes medications, as well as over-the-counter medications, supplements, and herbal remedies, may need to be adjusted or temporarily discontinued.
Allergies and Medical Conditions: Notifying the doctor about any medication or anaesthetic allergies, as well as existing medical conditions, will allow them to take the necessary precautions and ensure patient safety during the procedure.
Pre-Procedure Preparation: Patients will be asked to change into a hospital gown and remove dentures, glasses, or contact lenses before the procedure.
A gastroscopy involves several steps, which include:
After a gastroscopy, patients are monitored until the sedatives wear off, which usually takes 30 minutes to an hour. Once fully awake, they can start with small sips of water and slowly return to their normal diet, beginning with light, easy-to-digest foods. Activity should be limited for the rest of the day, and driving should be avoided for at least 24 hours due to lingering sedation effects.
Patients should follow their doctor’s instructions about resuming regular medications and watch for signs that need immediate medical attention, like severe abdominal pain, vomiting blood, or difficulty swallowing.
Follow-up appointments will review the gastroscopy results, any biopsy findings, and discuss further treatment or management plans.

Gastroscopy is generally a safe procedure, but like any medical procedure, it comes with some potential risks. The most common side effects are mild and temporary, including a sore throat, bloating, and mild abdominal cramps. These symptoms usually resolve on their own within a day or two and can be managed with simple remedies like lozenges or warm liquids.
While rare, there are more serious complications that may require medical attention. These include bleeding, particularly after a biopsy or polyp removal, infection at the biopsy site, and, in very rare cases, perforation of the stomach, duodenum, or oesophagus, which might need surgical repair. Despite these risks, gastroscopy remains a routine and generally safe procedure.

Mild discomfort is normal; however, if you experience severe pain, particularly in the chest or abdomen, or have difficulty breathing, contact your doctor immediately, as these may be signs of a complication.
The frequency of gastroscopy depends on the underlying condition being monitored or treated. Some conditions require regular monitoring, while others may not need follow-up procedures.
The procedure’s success is determined by the ability to examine the digestive tract and obtain clear images or biopsies. Your doctor will discuss the findings with you and any next steps.
Gastroscopy can be performed during pregnancy if necessary, but it is typically avoided unless there is a strong medical indication. The procedure will be carefully planned to minimise any risks to the mother and baby.
In most cases, the doctor will review the images and findings with you after the procedure. Some facilities may provide copies of the images for your records or to share with your doctor.
