You will be asked to sign a consent form authorizing the doctor to perform the procedure. Please let the doctor and GI nurse know if you are allergic to any medications. An IV will be placed in your arm vein prior to the procedure. Medicine will be injected through this needle to make you sleepy and relaxed. Your throat will also be sprayed with a numbing medicine. As you lay on your left side the nurse will place a small mouthpiece between your teeth. You will be able to breath normally.
The doctor will then place a flexible endoscope into your throat and advance it into the stomach, examining the lining of the esophagus, stomach, and duodenum. A biopsy specimen (small piece of tissue) may be taken for microscopic examination. You will not feel any sensation of discomfort when the biopsy is performed.
Many people do not recall any of the procedure because of the effect of the medicine. After the procedure you may feel drowsy and may sleep for a short time. The doctor will provide you with written report and instructions when you go home. Please feel free to ask the doctor or GI nurse or technician any questions you may have.
