Gastroscopy

Gastroscopy is a key diagnostic procedure used to investigate upper gastrointestinal symptoms and detect conditions such as reflux, ulcers, inflammation and coeliac disease. At BMI Clinics, our experienced clinicians perform gastroscopy with a strong focus on patient comfort, clarity of diagnosis and high-quality clinical care.

What Is a Gastroscopy?

A gastroscopy (also known as an upper endoscopy) uses a thin, flexible camera to examine the:

• Oesophagus

• Stomach

• Upper part of the small intestine (duodenum)

It allows clinicians to:

• Investigate symptoms such as heartburn, nausea, abdominal discomfort or difficulty swallowing

• Diagnose reflux-related conditions, gastritis and peptic ulcers

• Confirm or exclude coeliac disease

• Assess for bleeding or inflammation

• Take biopsies for accurate diagnosis

• Review the stomach before bariatric surgery when appropriate

Gastroscopy is a highly effective and minimally invasive way to understand upper digestive health.

Who May Need a Gastroscopy?

Your clinician may recommend a gastroscopy if you experience:

• Persistent reflux or heartburn

• Ongoing stomach pain or discomfort

• Unexplained nausea or vomiting

• Difficulty swallowing

• Iron deficiency or suspected bleeding

• Symptoms not responding to medication

• Positive coeliac screening tests

• Long-standing digestive concerns requiring further investigation

Gastroscopy may also be used as part of pre-operative assessment in selected patients.

Benefits of Gastroscopy

• Accurate diagnosis of upper digestive conditions

• Early detection of ulcers, inflammation or structural concerns

• Targeted treatment plans based on biopsy results

• A quick, low-risk procedure with minimal downtime

• Clear understanding of ongoing digestive symptoms

Preparing for Your Gastroscopy

Preparation is simple and usually includes:

• Fasting for several hours before the procedure

• Reviewing current medications with your clinician

• Receiving clear, written pre-procedure instructions

Our administrative and clinical team will ensure you know exactly what to expect.

During the Procedure

• Sedation is provided to ensure your comfort.

• The procedure typically takes 10–15 minutes.

• The clinician examines the oesophagus, stomach and duodenum.

• Biopsies may be taken if required — this is painless.

• You will be monitored throughout for safety.

Most patients find the experience straightforward and comfortable due to sedation.

Recovery & Aftercare

• You will rest in recovery until awake and stable.

• A support person must accompany you home.

• Mild throat discomfort may occur but generally settles quickly.

• Your clinician will discuss initial findings and provide follow-up instructions.

Biopsy results, if taken, are reviewed in detail once available.
