Olanzapine improves weight restoration better than placebo, without leading to adverse metabolic effects seen in individuals not in starvation. Alterations of the gut microbiome in anorexia nervosa have been demonstrated, but their clinical relevance remains unclear. Summary Medical complications of eating disorders may facilitate the first contact with health professionals and treatment initiation. Medical complications of anorexia nervosa generally occur due to starvation, malnutrition and their associated physiological effects, whereas medical complications of bulimia nervosa are generally due to purging behaviors.
