Well....
If you read some of my older posts/threads you will see that I had a bad time. Not only by the doctor who attempted to carry out the procedure but also some of the nurses.
I was offered the balloon as they thought it may better suits my eating habits buts its generally only given to those considered too large or unsuitable for going under anaesthetic.
The procedure (as you will know) involves a camera going down your throat & they do this to check for any abnormalities. As long as everything is okay they will put a second tube down which has the balloon in, they then inflate the balloon in your tummy with a dye. The reason for the dye is in case the balloon leaks you'll be able to tell when you have a wee.
The balloon is in for 6 months then you have to go back & do the procedure in reverse so they can remove it. The doctor who attempted to do mine was the rudest, most arrogant man I have ever had the misfortune to meet. He made an unpleasant experience much worse. But I'm a big believer in Karma
It wasnt Mr Small, Mr Balpuri or Mr Schroeder, or any of their team, but I daren't name him in case I get into trouble off the mods.
I have a real fear of gagging, being sick etc. so I was terrified anyway. However some people have no problems with endoscopy's & if that you then you'll be fine. You will need an endoscopy even if you end up having the bypass anyway, which I had in May. It wasn't as unpleasant as the one last September but it was the doctor who carried out the procedure who made the difference.
Hop this helps & I don't mean to scare you at all. My experience was well documented on here at the time.
Take care
