DSM-5
Anorexia nervosa is classified under the Feeding and Eating Disorders in the latest revision of the Diagnostic and Statistical Manual of Mental Disorders (DSM 5). There is no specific BMI cut-off that defines low weight required for the diagnosis of anorexia nervosa.The diagnostic criteria for anorexia nervosa (all of which needing to be met for diagnosis) are:
Restriction of energy intake relative to requirements leading to a low body weight. (Criterion A)
Intense fear of gaining weight or persistent behaviors that interfere with gaining weight. (Criterion B)
Disturbance in the way a persons weight or body shape is experienced or a lack of recognition about the risks of the low body weight. (Criterion C)Relative to the previous version of the DSM (DSM-IV-TR), the 2013 revision (DSM5) reflects changes in the criteria for anorexia nervosa. Most notably, the amenorrhea (absent period) criterion was removed. Amenorrhea was removed for several reasons: it does not apply to males, it is not applicable for females before or after the age of menstruation or taking birth control pills, and some women who meet the other criteria for AN still report some menstrual activity. Subtypes
There are two subtypes of AN:
Binge-eating/purging type: patients with anorexia could show binge eating and purging behavior. It is different from bulimia nervosa in terms of the individuals weight. An individual with binge-eating/purging type anorexia is usually significantly underweight. People with bulimia nervosa on the other hand can sometimes be normal-weight or overweight.
An overriding aorta is a congenital heart defect where the aorta is positioned directly over a ventricular septal defect (VSD), instead of over the left ventricle. The result is that the aorta receives some blood from the right ventricle, causing mixing of oxygenated and deoxygenated blood, and thereby reducing the amount of oxygen delivered to the tissues. It is one of the four findings in the classic tetralogy of Fallot. The other three findings are right ventricular outflow tract (RVOT) obstruction (most often subpulmonary stenosis), right ventricular hypertrophy (RVH), and ventricular septal defect (VSD).
