Loose stools, cold sweats, and passing out
Are your symptoms coming on after eating or drinking something? Or is it all of the time? I'm not sure how your surgeon could rule anything out without seeing you? In general the first few weeks after my RNY I had a hard time staying hydrated and couldn't tolerate milk. My best advice would be to make sure your sipping plenty of water and if you are actually passing out, are in pain or do not start to feel better soon go to the ER or at least speak with your surgeon again. Hope your feeling better soon.
