A long time friend of mine has had 4 or 5 episodes in the past 18 months that have been attributed to food poisoning and stress. The symptoms are vomiting, abdominal cramps and nausea. This was during a time when her father was terminally ill and died. Her adult son was diagnosed, paranoid schizophrenic and was in danger of physically harming himself and others. She is an only child and a single parent. are her symptoms characteristic of anything to be concerned with?
