My daughter is 13.5 years old she has very poor appetite. She does not eat anything in morning (says will vomit or having vomiting feeling ), basically we have seen its more of anxiety of going to school that she avoids eating .on weekends she does not complain of vomiting but no eating. Her weight gain and height gain last 5-10 years is below lowest curve. Worried of both, suggest anything for hunger and height.
