I thnk you should continue to do ab work as it will help stabilise your mid section, I also think they are talking about a more cosmetic problem. What is needed is tighter stomach muscles anyway. Having stronger abs will help you with other exercises, so in the long run it will pay off to continue to do them.
Doing those abs will also help with your posture as tightening those obliques and those smaller muscles help in realigning your spine, a better posture will also improve confidence levels and help in losing weight. So these things far outweigh the problem of having a bloated look for a while anyway.
I hope this was of some help.
P.S. keep up the good work, you will get back in no time
