Friend of mine, age 82, has attacks often 1 hour after eating anything. She feels very faint, has to lie down or really collapses with vomiting, diarrhea, shaking as in weakness. About an hour later she is stable, can get up, and feels much better. She recently had her gall bladder removed (stones), recent tests show anemia, a shadow on her lung, and a liver inflammation. She was recently at the ER 2x to be stabilized after vomiting, weakness, etc. So far no doctor know what is causing this condition. She s had an array of tests. Nothing indicates a single systemic cause. She had a heart attack about 3 years ago.
