can gastric bypass surgery be reversed?

Well, omission of facts is why I don't reply to a lot of posts anymore.  I came back tonight to say that my hematologist has been watching me closely due to anemia/low iron levels.  In a series of blood labs we discovered that I am critically low in potassium and am now on medication for it. I am greatly improved in the iron deficiency, still 11.1 but he is very happy.  I am not saying that you may be also low but that frequent labs are important.  You may also be allergic to milk, wheat, or any number of things.  That is easy to fix and several things need to be ruled out before you consider a reversal.  Something to think about.
