Seizures after RNY??
It's Reactive Hypoglycaemia - very simply put, it's when your blood sugar takes a dive after eating carbs/sugar without protein or fat. Some on here have got as low as 20 which puts you into seizure/death category - very scary!!! Martha (Multimom) has struggled with it badly (now doing much better, I believe) but most of us are able to control completely with eating every 2-3 hours and NOT eating just carbs/sugar on it's own!
If you do a search on the forum, it's talked about quite frequently ...
I hope this resolves for you - if any of us can help with more info please ask! (Martha's the one with a good handout which she's usually happy to e-mail if you ask nicely )
