  2. Anorexia Nervosa--Definition • Medical Definition • An eating disorder characterized by markedly reduced appetite or total aversion to food (<85% of ideal body weight for age & height) • A serious psychological disorder • Persons with this disorder may have an intense fear of weight gain, even when they are underweight. • They may diet or exercise too much, or use other methods to lose weight.

  3. Causes • Exact causes are unknown—Many factors are involved • Genes and hormones may play a role. • Social attitudes that promote very thin body types may also be involved. • Family conflicts are no longer thought to contribute to this or other eating disorders.

  4. Risk Factors • Being more worried about, or paying more attention to, weight and shape • Having an anxiety disorder as a child • Having a negative self-image • Having eating problems during infancy or early childhood • Having certain social or cultural ideas about health and beauty • Trying to be perfect or overly focused on rules

  5. Prevalence • Affects 0.5-2% of the population (1.5-6.2 million) • Anorexia usually begins during the teen years or young adulthood. • It is more common in females, but may also be seen in males. • The disorder is seen mainly in white women who are high academic achievers and who have a goal-oriented family or personality.

  6. Signs & Symptoms • To be diagnosed with anorexia, a person must: • Have an intense fear of gaining weight or becoming fat, even when she is underweight • Refuse to keep weight at what is considered normal for her age and height (15% or more below the normal weight) • Have a body image that is very distorted, be very focused on body weight or shape, and refuse to admit the seriousness of weight loss • Have not had a period for three or more cycles (in women)

  7. Signs and Symptoms • Psychological Symptoms • Cutting food into small pieces or moving them around the plate instead of eating • Exercising all the time, even when the weather is bad, they are hurt, or their schedule is busy • Refusing to eat around other people • Physical Symptoms • Blotchy or yellow skin that is dry and covered with fine hair • Confused or slow thinking, along with poor memory or judgment • Depression • Dry mouth • Extreme sensitivity to cold • Loss of bone strength
