Eating disorders

How are eating disorders related to PTSD?

Eating disorders include anorexia nervosa, which involves a lack of maintaining normal weight, usually less than 85% of the expected weight, and an intense fear of gaining weight. Bulimia nervosa involves the presence of binge eating followed by compensatory behaviours to prevent weight gain, while binge eating disorder does not involve compensatory behaviours.

What is the evidence for eating disorders in people with PTSD?

Moderate quality evidence found there may be increased rates of binge eating disorder or emotional eating in people with PTSD, although the evidence is very inconsistent.
