My daughter moved to a different city 2hours away for college, she left around December and ever since she has been gone she has been having problems with throwing up. She throws up at least once a week and its to the point that she only throws up clear liquids, and dry heaves. She s taken several pregnancy test and an ultra sound. She was 160lbs when she left and now she at 130lbs, I m scared that my child is slowly dying. Can you please give me some suggestions as to what could be going on with her.
