About the Gastroscopy (Endoscopy):

- The examination takes about 5-10 minutes.

- If you have dentures, please remove them before the examination. Lipstick must be removed.

- You will take an antifoaming agent before the examination to reduce the nausea caused by air bubbles when the endoscope is inserted. A topical anesthetic is made to your throat. Then your vital signs (blood pressure, pulse, respiration, etc.) are checked before your veins are secured with a heparinized cap, and then you lay down on the gurney.

- The endoscope is inserted into your mouth to duodenum gradually via, esophagus and stomach to check for abnormalities in the tissues.

- If necessary, a biopsy is taken for the purpose of examination and treatment which will be offered as an add-on with additional payment.

After the Gastroscopy (Endoscopy):

※ Do not drive after the sedative endoscopy.

- You can eat 20 minutes to 1 hour later when the throat anesthesia wears off unless there are specific instructions from your healthcare provider. If it is a sedative (sleep) endoscopy, you will be able to eat after 30 minutes to 1 hour rest.

- After the examination, you may feel like you have something stuck in your throat and your throat may be sore. This is a phenomenon that occurs when you give a lot of strength during the endoscopy. The symptoms are mostly relieved after a day or so.

- You may feel bloated and gassy in your stomach. This is natural, and the discomfort will subside as you release gas.

- You may feel swollen and sore around your ear and jaw joints. These are the symptoms of temporarily blocked salivary glands when force is applied during the endoscopy. Massaging around your chin with a lukewarm towel will help.
