A gastroscopy (upper GI endoscopy) is a vital diagnostic tool that allows doctors to examine your esophagus, stomach, and duodenum using a thin, flexible tube with a camera. It helps detect various digestive disorders early, leading to better treatment outcomes.
What is Gastroscopy?
Gastroscopy involves inserting an endoscope through the mouth into the upper digestive tract. The procedure is performed under sedation and helps:
✔ Diagnose digestive issues
✔ Collect tissue samples (biopsy)
✔ Treat certain conditions (like bleeding ulcers)
6 Common Conditions Diagnosed by Gastroscopy
1. Gastroesophageal Reflux Disease (GERD)
- Symptoms: Heartburn, regurgitation, chest pain
- Gastroscopy Findings: Inflammation, Barrett’s esophagus (pre-cancerous changes)
2. Stomach (Gastric) Ulcers
- Symptoms: Burning stomach pain, nausea, bloating
- Gastroscopy Findings: Open sores in the stomach lining
3. Gastritis (Stomach Inflammation)
- Symptoms: Indigestion, loss of appetite, vomiting
- Gastroscopy Findings: Redness, swelling, or erosion in the stomach
4. Hiatal Hernia
- Symptoms: Acid reflux, difficulty swallowing
- Gastroscopy Findings: Part of the stomach pushing into the chest
5. Celiac Disease
- Symptoms: Diarrhea, weight loss, fatigue
- Gastroscopy Findings: Damaged villi in the small intestine (confirmed via biopsy)
6. Esophageal & Stomach Cancer
- Symptoms: Difficulty swallowing, unexplained weight loss
- Gastroscopy Findings: Abnormal growths, tumors (biopsy confirms cancer)
Other Conditions Detected by Gastroscopy
- Esophageal strictures (narrowing)
- H. pylori infection (causes ulcers)
- Bleeding in the upper GI tract
What to Expect During a Gastroscopy?
- Before the Test:
- Fast for 6-8 hours
- Inform the doctor about medications
- During the Test:
- Given sedation for comfort
- Procedure takes 10-20 minutes
- After the Test:
- Mild throat discomfort may occur
- Avoid eating until numbness wears off
Is Gastroscopy Painful?
Most patients feel no pain due to sedation, just slight pressure.
Gastroscopy is a safe, effective way to diagnose GERD, ulcers, cancers, and other digestive disorders. If you have persistent stomach issues, consult a gastroenterologist for evaluation.
FAQs
1. How long does it take to recover from a gastroscopy?
You can resume normal activities the same day, but avoid driving for 24 hours due to sedation.
2. Can gastroscopy detect IBS (Irritable Bowel Syndrome)?
No, IBS is diagnosed based on symptoms since it doesn’t cause visible damage.
3. Are there risks to gastroscopy?
Rare complications include bleeding or perforation (less than 1% risk).
