Kahlua, I had the mini gastric bypass 7 years ago.  Believe it or not insurance use to cover this procedure but quit.  I had no complications or problems.  However, I never lossed amount of weight I probably should have with this surgery and I have regained about 50 lbs of my weight back.  I am seeking a revision.  I am talking with a Dr. in Florida who knows all about this procedure and as soon as I told him what I had he stated that I needed the true RNY.  The MGB is known for having a high rate for regain.  I am not trying to talk you out of what you are doing but I thought you should know the truth.  You really should connect with people who are 5 or more years out to see how successful they are with not regaining.  I know of several personally who have did the regaining.

I am a member on the CLOS site and have seen many posts from people who have issues.  Perhaps your removal was an error.

are there any major complications with having the mgb and a few years later end up pregnant?

You can find all the information you need at CLOS.net, the official MGB site.  I see on the Yahoo message board that lots of people come to the US from Canada---one doctor does the surgery in Michigan--and your national health plan covers it.  Check it out.  I had surgery 3 years ago and have gone from 392 to 175 with virtually no problems!  Good luck, and if I can answer any questions for you, feel free to ask.
