What is a Gastroscopy Procedure?
A gastroscopy, also known as an upper endoscopy, is a medical procedure used to examine the upper part of the digestive system. This includes the oesophagus, stomach, and the first part of the small intestine, known as the duodenum. The procedure is performed using a thin, flexible tube called an endoscope, which has a light and camera at its tip. This allows the doctor to view the inside of these organs on a screen.
Definition and Purpose
A gastroscopy is primarily used to diagnose and sometimes treat conditions affecting the upper digestive tract. It helps in identifying issues such as inflammation, ulcers, and tumours. The procedure is more accurate than X-rays for detecting these conditions and can also be used to take tissue samples (biopsies) for further analysis.
Common Indications
Gastroscopy is often recommended for individuals experiencing symptoms like persistent indigestion, upper abdominal pain, nausea, vomiting, or difficulty swallowing. It is also the best test for finding the cause of bleeding in the upper gastrointestinal tract. Other indications include:
- Unexplained weight loss
- Chronic heartburn
- Anaemia due to iron deficiency
Diagnostic and Therapeutic Uses
During a gastroscopy, the doctor can perform various diagnostic and therapeutic procedures. These include:
- Biopsies: Taking small tissue samples to diagnose conditions like coeliac disease or cancer.
- Polyp Removal: Removing small growths that could potentially become cancerous.
- Treatment of Bleeding: Cauterising bleeding sites to stop gastrointestinal bleeding.
Gastroscopy is a versatile procedure that not only helps in diagnosing but also in treating several gastrointestinal conditions, making it an invaluable tool in modern medicine.
Preparing for a Gastroscopy Procedure
Pre-Procedure Instructions
Before undergoing a gastroscopy, it’s crucial to follow specific instructions provided by your healthcare provider. These guidelines ensure the procedure goes smoothly and safely. Typically, you will receive information about what to expect and how to prepare. It’s important to adhere to these instructions; otherwise, the procedure may need to be rescheduled.
Medication Management
Inform your healthcare team about any medications you are currently taking, including over-the-counter drugs. Some medications, especially blood thinners like aspirin, clopidogrel, and warfarin, may need to be adjusted or temporarily stopped. Your doctor will provide specific instructions based on your medical history and the type of medication.
Fasting Guidelines
Your stomach must be empty during the gastroscopy procedure. Generally, you will be asked to fast for at least six hours before the procedure. This means no food or drinks, although you may be allowed to have small sips of water up to two hours before the procedure. Following these fasting guidelines is essential for a successful examination.
It’s essential to follow all pre-procedure instructions carefully to ensure the best possible outcome and avoid any complications.

The Gastroscopy Procedure: Step-by-Step
Sedation and Anaesthesia
Before the procedure begins, patients are usually given sedation to ensure comfort. This can be administered through an IV line. The level of sedation can vary from light to deep, depending on the patient’s needs awnd the healthcare provider’s recommendations. In some cases, general anaesthesia may be used.
Insertion of the Endoscope
- Positioning: The patient is positioned on their left side or back. A mouthguard may be used to protect the teeth and the endoscope.
- Throat Numbing: A numbing spray is applied to the back of the throat to reduce discomfort.
- Endoscope Insertion: A flexible endoscope, equipped with a light and camera, is gently inserted through the mouth and guided down the oesophagus into the stomach and duodenum.
Visual Examination and Biopsy
- Visual Inspection: The healthcare provider examines the lining of the upper digestive tract in real-time, looking for abnormalities such as inflammation, ulcers, or growths.
- Biopsy and Interventions: If necessary, tissue samples (biopsies) can be taken for further analysis. The procedure can also include therapeutic interventions like removing polyps or stopping bleeding.
It’s important to follow all pre-procedure instructions carefully and communicate openly with your healthcare team to ensure the best possible outcome.

Risks and Complications of Gastroscopy
In this section, we will delve into the risks associated with gastroscopy, emphasising that these occurrences are relatively uncommon but important to understand.
Potential Risks
- Bleeding
- Perforation
- Reaction to Sedation
- Infection
- Discomfort and Reaction to Scope Insertion
Managing Complications
- Immediate Response: Healthcare providers are trained to handle complications promptly. For instance, if significant bleeding occurs, measures such as cauterisation or clipping may be used to stop it.
- Post-Procedure Monitoring: Patients are usually monitored for a short period after the procedure to ensure there are no immediate complications.
- Follow-Up Care: In case of any complications, follow-up appointments are scheduled to monitor the patient’s recovery and address any issues.
When to Seek Medical Attention
If you experience any of the following symptoms after a gastroscopy, contact your healthcare provider immediately:
- Fever
- Trouble swallowing
- Increasing throat, chest, or abdominal pain
- Vomiting or nausea
- Other symptoms that cause you concern
While complications from a gastroscopy are rare, being aware of the potential risks and knowing when to seek medical attention can help ensure a safe and successful procedure.

Post-Gastroscopy Care and Recovery
Immediate Aftercare
After the gastroscopy, you will be monitored in a recovery area until the sedation wears off and you are fully alert. It’s important to rest for the remainder of the day. Avoid activities like driving or making important decisions, as the effects of sedation may linger.
Managing Side Effects
You might experience mild throat discomfort or bloating due to the air introduced during the procedure. These symptoms are usually temporary. Follow any dietary instructions given, starting with clear liquids and gradually progressing to a regular diet as tolerated.
Follow-Up Appointments
Your healthcare provider will discuss the findings of the gastroscopy with you and may recommend additional tests or treatments if necessary. Having a friend or family member with you during this discussion is advisable, especially if you had a sedative, as it can affect your memory. You may also receive a date for a follow-up appointment to discuss the results in more detail.
It’s crucial to follow all post-procedure instructions provided by your healthcare provider to ensure a smooth recovery.
When to Seek Medical Attention
While gastroscopy is generally safe, be aware of potential complications or unusual symptoms that require medical attention:
- Severe abdominal or chest pain
- Difficulty breathing or persistent coughing
- Fever
- Persistent or heavy bleeding from the mouth, throat, or rectum
- Difficulty swallowing or persistent nausea and vomiting
If you experience any of these symptoms, contact your healthcare provider immediately.

Gastroscopy in Diagnosing Gastrointestinal Conditions
Conditions Diagnosed
Gastroscopy is a valuable tool in diagnosing a range of gastrointestinal disorders:
- Peptic Ulcers: Gastroscopy can reveal the presence of peptic ulcers and erosions in the stomach or duodenum.
- Gastritis: Chronic inflammation of the stomach lining (gastritis) can be diagnosed through gastroscopy.
- Celiac Disease: In cases of suspected celiac disease, gastroscopy can help identify damage to the lining of the small intestine caused by gluten intolerance.
- Barrett’s Oesophagus: Individuals with chronic GERD may undergo gastroscopy to check for Barrett’s oesophagus, a precancerous condition.
- Helicobacter pylori: Through a simple tissue biopsy, Helicobacter pylori infection can be detected and hence the cause of gastritis or ulcers can be ascertained.
Role of Biopsies
During a gastroscopy, healthcare providers can take small tissue samples, known as biopsies, from suspicious areas. Biopsies are essential for further analysis under a microscope, aiding in identifying conditions such as gastritis, Helicobacter pylori infection, or even early signs of cancer.
Biopsies are crucial for diagnosing various gastrointestinal conditions, providing a clear picture of the underlying issues.
Therapeutic Interventions During Gastroscopy
Gastroscopy is not limited to diagnosis; it can also be therapeutic. In some cases, gastroscopy allows for the treatment of certain gastrointestinal conditions:
- Polyp Removal: Polyps in the stomach or oesophagus can be removed during a gastroscopy, reducing the risk of complications.
- Dilation: Gastroscopy can be used to dilate (stretch) narrowed areas of the oesophagus or stomach, relieving symptoms like dysphagia.
- Hemostasis: In cases of gastrointestinal bleeding, gastroscopy can be used to locate and treat the bleeding source through methods such as injections, cauterization or clipping.
