Answer

Gastrointestinal signs of anorexia nervosa include intestinal dilation from constipation and diminished intestinal motility.

Fecal occult blood may be indicative of esophagitis, gastritis, or repetitive colonic trauma from laxative abuse. Thyroid function tests, prolactin, and serum follicle-stimulating hormone (FSH) levels can differentiate anorexia nervosa from alternative causes of primary amenorrhea.
