As part of my ED Deep Dive series of blog posts, let’s focus on the first classification on the DSM-V’s list of eating disorders: anorexia nervosa (AN).

Clinical definition & presenting symptoms of anorexia nervosa

The diagnosis can be broken down further into two subtypes:

• Restricting type: Weight loss is accomplished primarily through dieting, fasting, and/or excessive exercise.

• Binge-eating/purging type: During the last three months the individual has engaged in recurrent episodes of binge eating or purging behavior (i.e., self-induced vomiting, or the misuse of laxatives, diuretics, or enemas).

Physiological effects of anorexia nervosa

Anorexia nervosa can adversely affect every system of the body:

• Neurological (brain and spinal cord) — difficulty concentrating, dizziness, fainting, sleep problems

• Musculoskeletal — enamel erosion, cavities, tooth sensitivity, muscle weakness

• Reproductive — amenorrhea (absence of a menstrual period), menstrual irregularities
