Gastroscopy (OGD)

Gastroscopy, also known as OGD (oesophago-gastro-duodenoscopy) or upper endoscopy, is a minimally invasive procedure that allows direct visualisation of the upper digestive tract. This procedure is essential for diagnosing conditions, performing biopsies, and treating various upper GI disorders.

Understanding Gastroscopy

Gastroscopy (OGD) involves passing a thin, flexible endoscope through the mouth to examine the oesophagus (food pipe), stomach, and duodenum (first part of the small intestine). It allows for direct visualisation, biopsy collection, and therapeutic interventions such as treating bleeding ulcers or dilating strictures.

Indications for Gastroscopy

  • Persistent heartburn or acid reflux not responding to medication
  • Difficulty swallowing (dysphagia)
  • Unexplained nausea, vomiting, or abdominal pain
  • Suspected peptic ulcer disease
  • Investigation of anaemia or iron deficiency
  • Surveillance of Barrett's oesophagus
  • Screening for gastric cancer in high-risk individuals
