OUCH! What is causing this? I have to admit reading this terrifies me, as my daughter at the worst of her eating disorder (anorexia/bulimia) was 90 lbs. at 5'4" - which would be relatively heavier than your daughter. Granted, body types differ, but your daughter is severely underweight for her height.
Does she have any digestive problems? (Celiac disease - gluten snsitivity - can be a cause of weight loss). Do you suspect an eating disorder or exercise bulimia? Please be careful here.
