My daughter has been sick for 2 years! First she just would feel ill after eating high fat/protein things. Now, everything she eats makes her sick. Once she puts something in her mouth, the nauseau hits within 30 seconds, followed by pain in the middle that radiates to the pancreas area and then to her back. She typically has to stop eating before she's finished because she begins gagging as if she will throw up if anything else goes down. Also, she has a bm within 30 minutes of every meal. The nausea and pain will last over an hour depending on what she ate. She's had the hida scan, upper gi, emptying study, ultra sound, endo, to no avail!
