I had several endoscopies in my earlier years as I suffered duadenal ulcers, I was lucky to be in the firms private health scheme at the time and always had sedation, absolutely
no problems what so ever. Fast forward to last year, aged 82, I needed an endoscopy to check my hiatus hernia so no problem anticipated but they decided, in their infinite wisdom, I did not need sedation, just a throat spray!!! I honestly thought I was going to choke to death, the whole experience was horrendous as the hernia was blocking the pathway they needed to take!!! I admit I am a wimp when it comes to medical matters, but this really was the most unpleasant experience of my life, carried out by a very junior person, who i suggested would be more suited to a career behind a butcher counter!!!! I was really crying as I was in so much discomfort and pain, never again, so please, do not let them talk you out of having sedation as it makes the world of difference.
