Comprehensive care for digestive disorders by Dr. Akeel Alisa
A gastroscopy, also known as an upper endoscopy or oesophago-gastro-duodenoscopy (OGD), is a procedure that allows a gastroenterologist to examine the upper part of the digestive system. Using a thin, flexible tube with a camera and light (endoscope), the doctor can view the oesophagus (food pipe), stomach, and duodenum (first part of the small intestine) in detail.
Gastroscopy is commonly used to investigate symptoms such as persistent heartburn, difficulty swallowing, nausea, vomiting, abdominal pain, indigestion, anaemia, or unexplained weight loss. It is also an important tool for detecting ulcers, inflammation, polyps, and early cancers.
Accurate diagnosis of upper digestive symptoms – Gastroscopy
provides direct visualisation of the oesophagus, stomach, and
duodenum, giving clearer results than X-rays or scans.
Early detection of cancer and precancerous changes – It allows
doctors to detect conditions such as Barrett’s oesophagus or
stomach cancer at an early stage, when treatment is most
effective.
Biopsies can be taken – Small samples of tissue can be collected
during the procedure to test for conditions such as Helicobacter
pylori infection, coeliac disease, or cancer.
Treatment during the same procedure – Gastroscopy can be used to
stop bleeding, stretch narrowed areas (dilatation), remove polyps,
or insert feeding tubes.
Your doctor may recommend gastroscopy if you experience:
To ensure a clear view, your stomach must be empty:
Gastroscopy is usually performed as an outpatient procedure.
You may be offered a local anaesthetic throat spray and/or
sedation to make you comfortable.
The endoscope is gently passed through the mouth, down the
oesophagus, and into the stomach and duodenum.
The doctor examines the lining carefully, takes biopsies if
needed, and may carry out treatment such as stopping bleeding or
dilating a narrowing.
The procedure usually takes 10–20 minutes.
You will be monitored afterwards until any sedation wears off and can normally return home the same day.
Gastroscopy is a very safe test. Complications are rare but may include:
A sore throat for a few hours afterwards
Minor bleeding after biopsies or treatments
Very rarely, perforation (a small tear in the lining)
Your specialist will explain the risks and answer any questions before the test.
When performed by an experienced consultant gastroenterologist, gastroscopy offers:
