Under weight: Would need more information. Is your appetite normal? Are you taking in enough calories? Do you have any symptoms such as nausea, abdominal pain or diarrhea? Is there a family history of gastrointestinal disorders? What is the weight of your parents and siblings? There are pills that stimulate appetite but this is to effective if your appetite is normal.
