Is it worth it?
Only you can answer that question. If you are gaining weight due to a medical reason then it sounds like no matter what you do you won't lose. But if people gain because they stopped working their tool and moved away from the basics then they may want to try getting back on track before going under the knife again. Good Luck to you!

Sounds like they are just saying that you had malabsorbtion with the original surgery, now you will just have the smaller stomach. That should be a big help tho if your stomach is smaller you won't be able to eat as much as now and if you stick to proper portion sizes it should help you to be able to lose even without the malabsorbtion. For me I think it would be worth it but that is something only you can decide in the end.
