Gastroscopy at Harmony
Gastroscopy, also called upper endoscopy, uses a thin flexible camera to examine the oesophagus, stomach and first part of the small bowel. It can help diagnose, and sometimes treat, conditions affecting the upper digestive tract.
When gastroscopy may be recommended
- Persistent reflux, heartburn or indigestion
- Difficulty swallowing or food sticking
- Nausea, vomiting or upper abdominal pain
- Unexplained weight loss or iron-deficiency anaemia
- Assessment for ulcers, gastritis, Barrett’s oesophagus or H. pylori
Same-day un-sedated gastroscopy
In selected cases, gastroscopy can be offered during a clinic appointment without sedative. A numbing throat spray is used to help tolerate the passage of the scope; the procedure itself usually takes around 7–10 minutes.
Preparation
You will usually need to fast for at least six hours. If you have diabetes or take blood-thinning medication, individual instructions will be given. Patients taking medicines such as Ozempic, Wegovy, Mounjaro, Zepbound or Saxenda should let the team know in advance.
Medicines before gastroscopy
- Blood pressure tablets are usually taken on the day of the procedure.
- Insulin, diabetes tablets and blood thinners may need temporary adjustment.
- PPIs such as omeprazole or lansoprazole may need to be paused before the test unless clinically unsuitable.
Results and biopsies
The endoscopy findings are reviewed with you and you receive a report and treatment plan. With your consent, a copy can be sent to your GP. Biopsy results are communicated when the pathology report is available.
Risks
Gastroscopy is commonly performed and serious complications are rare. Possible risks include sore throat, bloating, bleeding after biopsy, perforation and sedation-related reaction if sedation is used.
