I got a bowel obstruction from my gastric sleeve and had to have another surgery 2 days later

Yes, you can get a bowel obstruction from a port site hernia.  These are rare but they do happen.  Hunger does return in most patients after a sleeve gastrectomy.  In fact, some patients say they experience more hunger after the sleeve.  The good news is that portion control remains.  Acid reflux after the sleeve is fairly common.  You should be on an antacid such as Omeprazole or protonix for at least two months after the sleeve.  Be patient, as you continue to lose weight the reflux should get better.  

Your bowel obstruction was due to a loop of small bowel getting stuck in the abdominal wall defect left by the camera port.  This is not too uncommon.  It has absolutely nothing to do with your symptoms of reflux and heartburn.  This, too, is common after sleeve gastrectomy.  Often it gets better with time.  In the meantime, your doctor would probably suggest something like omeprazole (Prilosec) to alleviate your symptoms.  Does your doctor say he's never seen that before, too?
