Hello my name is Amber. I had gastric bypass rueny on 9/23 developed dumping syndrome while in the hospital. Weightloss was steady but now has stopped for 2 weeks. I also have been back since for dehydration. I have been having these episodes and hoping someone can assure me of normal or maybe has had this issue since. Yesterday I got really hot, then lightheaded which lead to a hollow feeling in my chest. I left work early and laid down. This morning it continues so dizzy unless I'm horizontal. Every time I stand or my eyes move side to side it feels like vertigo. My blood sugars are normal my water intake and food are fine. I write into my surgeon. Again. Has anyone expiernced this at all? I'm hoping so to find some answers
