Going to your original surgeon, if you are still in the same town, is a good start, but that should only be a start. As Tomo suggests, getting a second (and third, even,) opinion is a good idea, particularly for a revision where the needs and solutions are more varied than the original surgery. Talking to a non-surgeon or two (such as a gastroenterologist) is also a good idea as there may be some non-surgical interventions that can do the job, and it is usually preferable to start there anyway, and then consider surgery if those don't work.
Be suspicious of a surgeon who immediately tells you that if you have a sleeve, with GERD, that you need a bypass revision, without first doing some tests to find out what's really going on inside you. It may be a hiatal hernia which commonly causes GERD in WLS nd non WLS people alike, and that can be repaired without going through a revision (though some surgeons may not be comfortable or capable of doing so, or it can be a poorly shaped sleeve that inhibits good flow, and that can often be resleeved to correct that (though I probably wouldn't be depending upon the original surgeon to fix that, as it implies technique issues with the original surgery.)
In short, don't be too quick to self diagnose - let the professionals do that (though it pays to be well educated on it,) and play the field to get multiple opinions - they all can have somewhat different background and experiences, and that drives their opinions; don't settle for the first one that you come across.
goo luck in sorting this out....

What is the name of your surgeon. I'm needing revision surgery.
