Eating disorder - anorexia

Symptoms:

Most individuals with anorexia nervosa refuse to recognize (deny) that they have an eating disorder.

Symptoms may include:

  • Self-imposed food intake restrictions, often hidden
  • No menstruation
  • Skeletal muscle atrophy
  • Loss of fatty tissue
  • Low blood pressure
  • Dental cavities due to self-induced vomiting
  • Blotchy or yellow skin
  • Depression
