Digestive problems are among the most common health issues faced by people worldwide. Symptoms such as abdominal pain, bloating, acid reflux, nausea, vomiting, heartburn, or unexplained weight loss often require proper medical evaluation—especially when persistent. One of the most accurate ways to diagnose conditions affecting the upper digestive tract is gastroscopy, also known as upper GI endoscopy.

In recent years, Vietnam has become a leading destination for gastroscopy, offering world-class medical standards, advanced endoscopy equipment, internationally trained specialists, and highly competitive pricing. Many travelers combine medical care with tourism, making Vietnam one of Asia’s most accessible and cost-effective places to undergo gastroscopy.

This comprehensive guide covers everything you need to know about gastroscopy in Vietnam—from the procedure, benefits, preparation, costs, hospitals, risks, and recovery, to why international patients trust Vietnam for digestive diagnostics.

What Is Gastroscopy?

Gastroscopy (upper gastrointestinal endoscopy) is a minimally invasive procedure that uses a thin, flexible tube with a camera and light (endoscope) to examine the:

• Esophagus

• Stomach

• Duodenum (the first part of the small intestine)

The endoscope is inserted gently through the mouth, allowing the doctor to see the lining of the upper digestive tract in real time on a high-definition screen.

A gastroscopy can both diagnose and treat certain conditions, making it one of the most valuable tools in gastroenterology.

Why Do You Need a Gastroscopy?

Doctors may recommend gastroscopy if you have symptoms such as:

• Persistent heartburn or acid reflux (GERD)

• Upper abdominal pain

• Chronic nausea or vomiting

• Difficulty swallowing (dysphagia)

• Black or bloody stools

• Vomiting blood

• Unexplained anemia

• Loss of appetite

• Bloating or indigestion

• Suspected H. pylori infection

Gastroscopy is also essential for cancer screening, especially stomach cancer and esophageal cancer.

What Conditions Can Gastroscopy Detect?

Gastroscopy can identify a wide range of upper GI conditions, including:

1. Gastritis

Inflammation of the stomach lining caused by stress, spices, alcohol, or infection.

2. Peptic Ulcers

Sores in the stomach or duodenum, often caused by H. pylori or NSAIDs.

3. H. pylori Infection

A common bacterial infection that can lead to ulcers and increases the risk of stomach cancer.

4. Hiatal Hernia

A condition where part of the stomach pushes into the chest cavity.

5. Esophagitis

Inflammation of the esophagus due to acid reflux or allergies.

6. Barrett’s Esophagus

A serious complication of chronic reflux that increases cancer risk.

7. Stomach Polyps

Small growths that can be benign or precancerous.

8. Upper GI Bleeding

Gastroscopy can locate and sometimes treat bleeding in the upper GI tract.

9. Early Gastric Cancer

High-quality endoscopy can detect cancer at its earliest stages.

10. Celiac Disease

Biopsies can confirm gluten-related intestinal damage.

Gastroscopy is also used for monitoring chronic GI conditions and assessing treatment effectiveness.

Why Choose Gastroscopy in Vietnam?

Vietnam has become a preferred destination for medical tourists seeking high-quality diagnostic endoscopy. Here’s why:

1. Advanced Endoscopy Technology

Vietnam’s top hospitals use state-of-the-art equipment such as:

• Olympus EVIS EXERA III / EVIS X1

• Fujifilm ELUXEO systems

• Narrow Band Imaging (NBI)

• Blue Light Imaging (BLI)

• 4K resolution endoscopes

• Endoscopic Ultrasound (EUS)

These technologies improve visualization and help physicians detect early abnormalities, especially early-stage cancers.

2. Highly Skilled GI Specialists

Vietnamese gastroenterologists are experienced in high-volume clinical practice and often receive international training in:

• Japan

• South Korea

• France

• Germany

• Singapore

• Australia

Many doctors perform thousands of gastroscopies per year, giving them a high level of diagnostic accuracy.

3. Safe, Painless Sedation Techniques

International hospitals in Vietnam offer:

• IV sedation

• Light anesthesia

• Continuous monitoring

• Recovery rooms with nurses present

This ensures patients remain comfortable throughout the procedure.

4. Affordable Costs

Gastroscopy in Vietnam costs significantly less than in Western countries.

Average Cost (USD)

Vietnam offers international-level quality at a fraction of the cost.

5. Fast Scheduling & Quick Results

Unlike many Western countries with long waiting lists, Vietnam offers:

• Same-day or next-day appointments

• Immediate preliminary results

• Biopsy results within 3–5 days

This is ideal for travelers with limited time.

6. English-Speaking Staff & International Patient Support

Most major hospitals provide:

• English interpreters

• Coordinators for foreign patients

• Clear instructions

• Assistance with transportation and accommodation

This makes medical travel smooth and stress-free.

How Gastroscopy Is Performed in Vietnam

Here’s what you can expect during the examination.

1. Preparation

Before the procedure:

• No food or drinks for 6–8 hours

• Bring your medical records (if any)

• Notify staff of allergies, medications, heart or lung conditions

If you are doing a combined gastroscopy + colonoscopy, additional bowel preparation may be required.

2. Sedation

Patients receive light IV sedation so they:

• Do not feel pain

• Do not gag

• Are relaxed throughout the procedure

You will not be fully unconscious, but you will feel comfortable and calm.

3. The Procedure

Duration: 5–10 minutes

Steps:

1. A mouthguard is placed to protect your teeth.

2. The flexible endoscope is inserted through the mouth.

3. The doctor examines the esophagus, stomach, and duodenum.

4. If abnormalities are found, biopsies can be taken immediately.

5. Images and videos are recorded for your medical report.

The procedure is painless due to sedation.

4. Recovery

• Rest in a recovery room for 20–30 minutes

• Mild throat soreness can occur

• You may eat soft foods after 1–2 hours

• Avoid driving for 12–24 hours

You will receive a detailed report and instructions.

Additional Tests During Gastroscopy

1. Biopsy

A small tissue sample may be taken to check for:

• H. pylori infection

• Cancer cells

• Chronic inflammation

Biopsies are painless and safe.

2. Rapid H. pylori Test

A quick test using a tissue sample from the stomach lining.

3. Polyp Removal

Small stomach polyps can be removed during the procedure.

4. Endoscopic Treatment

Some hospitals in Vietnam can:

• Stop bleeding

• Remove foreign objects

• Treat small lesions

Is Gastroscopy Safe in Vietnam?

Yes. Gastroscopy is considered very safe, especially in hospitals using modern equipment and sedation techniques.

Potential risks are rare and include:

• Mild sore throat

• Temporary bloating

• Very rare risks (<1 in 10,000): bleeding or perforation

Vietnamese hospitals follow strict sterilization and infection-control protocols.
