My daughter has anorexia and is struggling to increase her food intake. She has started to do this, but now has this overwhelming feeling that she is going to be sick . She has this in her stomach but it is mainly in her throat. So as a result she doesn't feel like eating and thus her weight is beginning to go back down. Has anyone else experienced this? Is this psychological or could there be some medical problem? GP has given her antibiotics but couldn't see any problem.
