Regarding the Barium Enema.....I had one about 2 years ago and it really was not that bad. I'm the biggest wimp there is and managed to go through it with flying colors. The worst part is the prep (cleaning yourself out)....What they do is instert a small tube with a little balloon on the end of it....They fill the balloon with air which fills you with some air also. You are lying on a bed on your side while this is happening...It is not painful at all....Once the barium starts going in, you feel it, but it's only because it's cold. Again, it does not hurt. The bed you are lying on moves (tilts) forward and back so that the barium can work it's way through your intestines. The doctor will ask you to move onto your back for a short period of time, just to get it all through. It does not take that long (maybe 3-5 min at the most) and then the hard part comes.....You have to hold it in. You feel like going to the bathroom, but you can't. This is when they will take the x-rays. The good part is that for most of them you are lying down on a bed. So it's easier to hold it...but hard for the ones that you have to stand for. Then they have to make sure that all the x-rays turn out before you are allowed to go to the bathroom. (If you have a nice tech, they might let you see some of the x-rays. I managed to get a peek of mine. Kind of interesting to see.) Bathroom Warning - Make sure that no one is nearby. This is the point where you will remove all the air and barium that they have entered into your intestines. I thought I was going to rocket myself aross the world. It was a little embarrassing to say the least. But, as I mentioned, it is not painful at all. Good Luck!
