To tell you truth I was just like you as scarred as hell and worried but as I had Throat Spray as banana flavour, so no pain I can get, as well I was given sedative as it makes you calm down but not sleep as my experience. I was seen on time of my appointment, a nurse came and took me to a room where she interviewed me of her questions, She will ask you if you took any medication as well, you need to sign as well because you asked them to do a throat spray and sedative. A GI Doctor will come to see you and put a needle in your right hand and inject you with a water first, its safe don't worry about it, you can also ask the doctor to take a little biopsy for to see if you have h.pylori, doctor will ask you that as well for your permission, its good thing. A nurse will come and take you to the Endoscopy room: What will happen now is that you will not lay down in the bed but sitting on it, your doctor will spray a banana flavour in your throat and you need to swallow it like 2 to 3 times and than she will put the sedative with needle in your hand and than you will lay down now on your left side, they will put a small thing in your mouth as to be safe to put long tube in your stomach. Listen you can swallow normally near your throat and you feel gas a little bit and you will burp a little, to tell you truth of the pain is only for 2 sec, you won't feel that pain either, a nurse will be with you and hold your hand as well, you are going to feel very good relaxation. When the Endoscopy is finished, they will take you straight to the recovery room, you are going to be there around 30mins: a nurse will ask you straight away if you want a tea or water with biscuits, I asked water its better for me was, and biscuits was so delicious. In 10 mins later you will get your report of your endoscopy but not for biopsy, that will take time,: in the report would say all is normal, if it doesn't say in the report of hernia hiatus it means you don't have it. To tell you truth when I was in the recovery, I said to myself that endoscopy was amazing, I want to do right now, it was so fun.
Listen to me, I am going to show you a trick, you think you can't open your mouth that long or swallow much? so what I want you to do at home is open your mouth atleast for 10 mins and you will see the results that you can do it and its so easy. My endoscopy took less than 5 mins.
