Gastroscopy — or upper gastrointestinal endoscopy — lets doctors look directly inside your esophagus, stomach and duodenum using a thin, flexible camera. It is the gold standard for investigating persistent heartburn, upper abdominal pain, difficulty swallowing and unexplained bleeding. 🔍

Gastroscopy procedure

At Daqi Hospital, our gastroenterology team uses high-definition scopes to spot early lesions, ulcers and precancerous changes — often before symptoms appear.

What to expect during the procedure 📋

Step What happens
1. Preparation Fast for 8 hours; stop certain medications as advised
2. Sedation A light sedative keeps you relaxed and comfortable
3. Examination The scope passes gently, 10–15 minutes total
4. Biopsy (if needed) Tiny samples are taken for lab analysis
5. Recovery You rest 1–2 hours, then go home the same day

When should you ask your doctor? 🚨

  • Chronic heartburn or acid reflux despite treatment.
  • Pain or difficulty when swallowing food.
  • Black or bloody stools.
  • Unexplained weight loss or iron-deficiency anemia.
  • A family history of stomach or esophageal cancer.

Don’t let digestive symptoms linger. Speak with a Daqi Hospital gastroenterologist about whether gastroscopy is right for you. 🏥
