Let me tell you of my story and you can decide for yourself. I've had a little, if only a fraction of indigestion before the band. But it was easy not to notice because the food kept it down. I ate a lot to take care of a that nagging hungry feeling.
Since being banded I too have developed Gerd. I lived with it for about 6 months before I was willing to go back to the doctor because I had lost a lot of weight and honestly I thought I didn't want to change any of that.
What I know know, is when I don't eat so much, I do have acid reflux or Gerd and all that eating before surgery was to surpress it. Now that there is not so much food disguising what was once mild symptoms has clearly raised it's head when there's less food coming in.
It's all a balancing act - he took some fluid out and I now feel much better.
I commend you for trying to find the answers but I wouldn't be so quick to blame your doctor. You're young, you're still starting out, you'll get there.
