Reactive Hypoglycemia question

Hello,

I too have Reactive Hypoglyceamia and the only way this was confirmed was by having a glucometer (Diabetes pi ***** thingy) and when i ate either high sugar or high carb meal I would get bluured vision, cold sweats, dizzy and so I was tested at the point and blood sugar was sky high and then I was so extreme I would pass out cold on the floor and then I was tested again at that point and blood sugar had bottomed out causing me to faint.  This I had with my VSG surgery and now I'm an RNY Bypass I imagine it will be the same if not worse reaction for me.
