Preparing for a Gastroscopy: What Patients Should Know

1 month ago 18

A gastroscopy is a procedure used to examine the upper digestive tract, including the oesophagus, stomach, and the first part of the small intestine. It may be recommended for symptoms such as persistent stomach pain, acid reflux, swallowing difficulties, nausea, bloating, or unexplained gastrointestinal bleeding.

Understanding how to prepare for the procedure may help reduce anxiety and support a smoother examination process.

What Is a Gastroscopy?

Gastroscopy, also called upper gastrointestinal endoscopy or upper endoscopy, involves passing a thin flexible tube with a camera through the mouth and into the upper digestive tract.

The procedure allows doctors to examine the lining of the digestive tract and identify possible causes of symptoms.

A gastroscopy may also allow:

  • Tissue biopsies
  • Assessment of inflammation or ulcers
  • Investigation of bleeding
  • Removal of selected polyps or foreign bodies in some cases

Why Might a Gastroscopy Be Recommended?

A gastroscopy may be performed to investigate symptoms such as:

  • Persistent abdominal pain
  • Acid reflux or heartburn
  • Difficulty swallowing
  • Nausea or vomiting
  • Bloating
  • Unexplained weight loss
  • Vomiting blood
  • Black stools
  • Anaemia related to possible gastrointestinal bleeding

It may also be used to monitor certain digestive conditions or evaluate abnormal imaging findings.

A gastroscopy may also be used to assess a hiatus hernia, which occurs when part of the stomach moves up through the diaphragm into the chest area. 

Preparing Before the Procedure

Fasting Instructions

Patients are usually advised not to eat or drink for several hours before the procedure. This helps ensure the stomach is empty so the doctor can examine the digestive tract more clearly and reduce the risk of aspiration during sedation.

Specific fasting instructions may vary depending on:

  • The appointment time
  • Type of sedation planned
  • Existing medical conditions

Patients should follow the clinic or hospital’s instructions carefully.

Medication Considerations

Patients should inform the doctor about:

  • Blood-thinning medication
  • Diabetes medication
  • Allergies
  • Existing medical conditions
  • Previous reactions to sedation or anaesthesia

In some cases, medication adjustments may be required before the procedure. Patients should not stop prescribed medication unless advised by their doctor.

Sedation During Gastroscopy

Gastroscopy may be performed:

  • With sedation
  • Without sedation in selected cases

Sedation may help patients feel more relaxed and comfortable during the procedure.

If sedation is used, patients are usually advised:

  • Not to drive after the procedure
  • To arrange transport home
  • To avoid important decisions or alcohol for the rest of the day

Recovery from sedation varies between individuals.

What Happens During the Procedure?

Before the procedure begins:

  • Patients may change into a gown
  • Monitoring equipment may be attached
  • A local anaesthetic spray may be used to numb the throat
  • Sedation may be administered if planned

During the gastroscopy:

  • The endoscope is passed gently through the mouth into the oesophagus and stomach
  • Air or carbon dioxide may be introduced to improve visibility
  • The doctor examines the digestive tract lining
  • Biopsies may be taken if required

The procedure usually takes a short period of time, although the duration varies depending on the findings and whether additional procedures are performed.

Is Gastroscopy Painful?

Many patients describe gastroscopy as uncomfortable rather than painful. Some may experience:

  • Gagging sensations
  • Pressure in the throat
  • Mild bloating from introduced air

Sedation may reduce awareness of discomfort during the examination.

What Happens After the Procedure?

After gastroscopy, patients are usually monitored until the effects of sedation begin to wear off.

Some temporary symptoms may include:

  • Mild sore throat
  • Bloating
  • Burping
  • Mild drowsiness if sedation was used

These symptoms often improve within a short period.

Eating and Drinking After Gastroscopy

Patients are usually advised when it is safe to resume eating and drinking. Recommendations may depend on:

  • Whether sedation was used
  • Whether biopsies were taken
  • The findings during the procedure

Soft foods and fluids may initially be recommended in some cases.

Possible Risks and Complications

Gastroscopy is generally considered a commonly performed procedure, but potential risks may include:

  • Bleeding
  • Infection
  • Reaction to sedation
  • Injury or perforation of the digestive tract
  • Breathing-related complications associated with sedation

The overall risk varies depending on the patient’s health and whether additional procedures are performed.

When to Seek Medical Attention After Gastroscopy

Patients should seek prompt medical review if they experience:

  • Severe abdominal pain
  • Fever
  • Difficulty breathing
  • Vomiting blood
  • Black stools
  • Persistent chest pain
  • Difficulty swallowing that worsens
  • Severe dizziness or fainting

These symptoms may require urgent assessment.

Questions Patients May Ask Before Gastroscopy

Patients may consider asking:

  • Why is the gastroscopy being recommended?
  • Will sedation be used?
  • How long should I fast beforehand?
  • Do I need to stop any medication?
  • Will biopsies be taken?
  • When will results be available?
  • What symptoms should prompt medical review afterwards?

Preparing for a gastroscopy usually involves fasting, reviewing medications, and understanding what to expect before, during, and after the procedure. Gastroscopy allows doctors to examine the upper digestive tract and investigate symptoms such as reflux, stomach pain, swallowing difficulties, and gastrointestinal bleeding. Following preparation instructions and post-procedure advice may help support a smoother recovery process
