her daughter’s eating habits. The mother states the she will not eat anything
and is obsessed with exercise and losing weight. She also states that her daugh-

the mother, the patient comes in for a physical examination. The patient is 5 ft

depressed affect. The patient states she is worried that her friends will think
she is fat if she eats more. She denies any binge eating. Her physical exami-
nation is normal, other than dry skin and thin fine hair on extremities.
Laboratory tests reveal that she is anemic and has a low albumin and magne-
sium level. She has normal liver and thyroid tests.
