 Females with bulimia may also experience amenorrhea, although the cause is not clear.Two subtypes of anorexia nervosa are specified in the DSM-5—restricting type and binge-eating/purging type.Those who have the restricting type of anorexia nervosa restrict food intake and do not engage in binge eating, whereas those with the binge/purge type lose control over their eating at least occasionally and may compensate for these binge episodes.
