I had the sleeve in 2011. I lost 135 pounds but have gained back 76 pounds. It is very disappointing. I thought the weight would be gone forever. Does anyone know if the gastric bypass can be done after the sleeve? Other question is , I was diagnosed with Osteoporosis and the Dr. Wants to start me on Bonivia, Fosamax. But not sure if any of the oral meds can be taken since I have had the surgery. Thanks .
