Looking for some opinions about whether I need to be pushing for more tests for my daughter. She is now 7, but since she was a toddler she has had random vomiting episodes on a fairly regular basis. They tend to follow quite a distinct pattern: she wakes up earlier than usual, maybe around 5am, saying that she feels "wobbly". She will be white as a sheet and quite uncommunicative. Shortly afterwards she starts vomiting, sometimes just the once but often multiple times. She will then fall asleep and when she wakes up she is pretty much better and starts asking for food. The whole thing is usually over by lunchtime with no lasting effects. When she was younger it would happen probably once every two to three months. Recently it hasn't been just as often but it has come back with a vengeance and she has had three episodes this month. I'm going to take her to the doctor but in the past when I've raised it with them they have been quite dismissive, so my question is is this something that just happens sometimes and nothing to worry about, or should I really be pushing for them to investigate further to try and find a cause?
