Gastroscopy

What Is Gastroscopy?

Gastroscopy, also known as upper endoscopy or esophagogastroduodenoscopy (EGD), is a diagnostic procedure that allows doctors to examine the lining of the esophagus, stomach, and upper part of the small intestine (duodenum) using a flexible tube called a gastroscope.

The procedure is commonly used to diagnose a range of upper gastrointestinal (GI) conditions, detect abnormalities, take tissue biopsies, and sometimes perform treatment interventions.

Common Reasons for Gastroscopy

Gastroscopy may be recommended for patients experiencing:

  • Persistent upper abdominal pain

  • Difficulty swallowing (dysphagia)

  • Chronic heartburn or acid reflux

  • Vomiting or nausea without known cause

  • Gastrointestinal bleeding

  • Suspected ulcers, gastritis, or tumors

It is also a follow-up tool for patients with a history of Barrett’s esophagus or gastric ulcers.


How the Procedure Works

At Vibhavadi Hospital, our gastroscopy is performed under sterile, safe, and comfortable conditions by trained gastroenterologists.

Preparation

  • Patients are asked to fast for at least 6–8 hours before the procedure

  • Anticoagulant medications may be paused temporarily if needed

  • A consent form is signed prior to the procedure

During the Procedure

  • A local anesthetic is sprayed into the throat

  • Sedation may be administered for comfort

  • A thin flexible scope with a light and camera is inserted through the mouth and guided into the esophagus, stomach, and duodenum

  • The physician examines the lining for signs of inflammation, ulcers, bleeding, or abnormal growths

  • Tissue samples (biopsies) may be taken if necessary

The entire process usually takes about 15–30 minutes.

Recovery

  • Patients are monitored in a recovery room

  • Mild throat discomfort may be present temporarily

  • Normal activities can usually resume the same day, unless sedatives were used


Conditions Diagnosed with Gastroscopy

Gastroscopy is essential for diagnosing and evaluating:

  • Gastritis and peptic ulcers

  • Gastroesophageal reflux disease (GERD)

  • Esophageal strictures or varices

  • Esophageal and gastric cancers

  • Barrett’s esophagus

  • Helicobacter pylori infection

  • Celiac disease

  • Polyps and bleeding sources

Frequently Asked Questions (FAQ)

Q: Is gastroscopy painful?
A: Most patients feel only minor discomfort. Sedation is often used to make the experience more comfortable.

Q: How long does it take to get results?
A: Immediate findings can be discussed right after the procedure. Biopsy results may take 3–5 days.

Q: Is it safe to undergo gastroscopy?
A: Yes. It is a very safe procedure with minimal risks, especially when performed by experienced physicians.

Q: Can I eat after the procedure?
A: Once the throat numbing wears off (usually 30–60 minutes), you can resume eating, unless advised otherwise by your doctor.

Q: How often should I have a gastroscopy?
A: Frequency depends on individual risk factors or previous findings. Those with GERD, Barrett’s esophagus, or ulcer history may need regular monitoring.
