Grazie Rikneilson. I'm getting to know my new GI system better now. Portion sizes have increased and I get fewer episodes of what seems to be dumping syndrome. The two theories and I emphasize the word theories are that it's due to sugar regulation and insulin rebound or undigested food dumping out of the stomach too soon. I don't fit cleanly into either of these. I was trying to find out WHY this happens so that I could avoid it, but I don't think i'll find the answer with western medical docs. They don't know, nor care. They will blabber on about not too much in one sitting , small frequent meals, low glucogenic foods, healthy fats, etc. I think that Gary is correct when he says that the body will "rewire itself and figure it out".

My question to the group that has the episodes of tachycardia, lightheadedness, and extreme loss of energy after eating. How do you prevent it? Any clue what triggers it? I can answer for me. Too much food "it's that last bite that will get ya" Drinking any fluid with or after I eat also triggers it. To treat it, I lay down and rest as soon as possible. If I fight it, it gets exponentially worse.
