Low Blood Sugar (Dumping?)

 Hello my name is Melinda, and this november will be my 4 year of post op.  i've recently had these symptoms also and worry that they can get worse.  I had a miscarage about 4 months ago and had gained some of my weight.  I am now doing my protien diet and watching my sugar.  I am wondering if anyone else has gained their weight and if you have what you are doing to lose.
