Dear Sir/Madam:


    Thank you for choosing Jiahui Medical Endoscopy Center for gastroscopy examination/treatment. We sincerely wish to provide you with the best quality health care patient experience. To fully prepare for your gastroscopy examination/treatment, please pay attention to the following instructions:


    Before your gastroscopy

    1. Please stop eating and drinking by 8.00pm in the evening before the examination. Please remember to refrain from taking breakfast and drinking water on the morning of the examination. A few days before the examination, please start having light meals. Avoid eating spicy food and smoking. 

    2. On the day of examination, please wear comfortable clothing, as you will be requested to change into an examination gown before the examination. You will also be requested to remove and keep your dentures before the examination.

    3. Prior to the examination, please let your doctor know if you have any of the following medical conditions: high blood pressure, coronary heart disease, arrhythmias, respiratory disease, coagulation disorders or drug allergy.

    4. If you are having the gastroscopy examination without sedatives, please cooperate by swallowing when your doctor is inserting the endoscope. If there is any nausea or vomiting, your doctor may instruct you to take slow deep breaths. Usually with good preparation and cooperation, the examination can be smooth with less unpleasant effects.

    5. If needed, your doctor may send some of your gastric tissue or cells for biopsy tests if he or she sees anything suspicious. This procedure is usually harmless.

    6. Please let your doctor know if you are taking any of the following blood-thinning medications: aspirin, clopidogrel (brand name Plavix, Talcom etc.), warfarin, etc. If necessary, your doctor might request you to stop taking these medications 5 to 7 days before the examination.

    7. We do not recommend the examination be done if you are pregnant or having your period (menstruation).

    8. Please tell your doctor or nurse if you have a cold or a blocked nose.

    9. On the day of examination, please also remember to bring all your medical records and relevant medical tests results and reports.
