My daughter had her gallbladder out approximately 2 1/2 months ago. She has been having intermittent pain in her upper abdominal region. Last night she had a severe attack, vomiting, explosive diahrea, then she pasted out for a minute. She has a history of hypoglycemic episodes. I'm not sure how to help her avoid these attacks. We ate at a Japanese Steak house last pm. She had salad, steak, shrimp and chicken with fried rice.
