Your pre-test checklist
Confirm when and where to arrive
Check the date, arrival time and exact clinic or hospital with the nurses. Allow time for registration and preparation; the arrival time may differ from the test time.
Follow your preparation instructions
Six hours of fasting is required before OGD. Confirm when to stop eating and drinking with the nurses, and follow your individual instructions. Contact them before travelling if you have not followed the fasting instructions.
Check medicines and health information
Please tell the nurses about medicines you take (especially blood thinners or diabetes medicines), medicine allergies, and relevant medical conditions. Do not stop or change prescribed medicines unless advised by your healthcare professional.
Pack what you need
Bring identification, your appointment or referral information if available, a current medicine list and any relevant previous reports. If claiming insurance, bring your insurer card or policy details and claim forms if available; these insurance documents are optional.
Arrange your journey home if sedated
Arrange for a responsible adult to accompany you home and help afterwards as instructed. Do not plan to drive yourself home. Confirm the escort requirements and how long driving, alcohol, machinery and important decisions must be avoided; tell the nurses in advance if no escort is available.
Confirm your location
Consultations and endoscopy can be arranged on Hong Kong Island or in Kowloon. Confirm the exact location with the nurses when arranging an appointment.
Private hospitals
If your examination is arranged at a private hospital, confirm the hospital and time with the nurses.
What happens, benefits and follow-up
During the examination, the doctor guides a thin, flexible endoscope through the mouth to inspect the oesophagus, stomach and duodenum. A small amount of air or gas may be used to open the stomach, and fluid may be suctioned away. Gagging, belching or temporary bloating can occur. Throat spray or sedation depends on the plan for you; the nurses can explain your arrangements.
An OGD can help investigate upper digestive symptoms and identify visible changes such as inflammation or ulcers. It shows the lining that can be seen during the examination and cannot diagnose every condition. If appropriate, the doctor may take small tissue samples (biopsies) for laboratory examination. Sampling is not usually felt as sharp pain; the team will explain how and when results and follow-up will be discussed.
Serious complications are uncommon, but can include bleeding, perforation, and reactions related to sedation if it is used. A temporarily sore throat or bloating may follow. Follow the care and discharge instructions given by your team. If sedated, follow their advice about driving and having someone assist you. Seek urgent medical care for severe or worsening chest or abdominal pain, fever, breathing difficulty or significant bleeding.

A temporarily sore throat or bloating may occur after OGD. If throat spray was used, wait until the team says swallowing is safe before eating or drinking.
Rest in the recovery area until the team considers you ready to leave. Follow the written discharge advice on food, drink, medicines and activity. After sedation, leave with your arranged escort and follow the restrictions given by the team.
Results and follow-up
Dr Paul Ng is responsible for your follow-up. The team will explain the findings when you are ready; biopsy or polyp laboratory results may still be pending. Before leaving, confirm how and when to obtain your results, whether a follow-up appointment is needed and whom to contact if you have not heard back as arranged.
When to seek help
Seek urgent medical care for severe or worsening chest or abdominal pain, fever, breathing difficulty, vomiting blood or significant bleeding.
For severe symptoms, go to an emergency department or call 999 in Hong Kong. Do not wait for a WhatsApp or WeChat reply. For non-urgent recovery or results questions, contact the nurses using your discharge contact details or the clinic contacts below.
