Done estimated finish: 33min left Overview of Eating Disorders / Anorexia Nervosa Overview Anorexia nervosa is characterized by the restriction of food intake to the point at which actual caloric intake is dramatically less than the daily requirements with the intention of significant weight loss. Several psychological factors are associated with anorexia nervosa, such as fear of gaining weight, excessive behaviors such as exercising, and an obsession with food and appetite suppression. These psychological factors can consume the life of the patient with anorexia. Their appetite does not diminish from the lack of food intake; instead, they find methods to suppress it to tolerable levels, eating only eating minimal amounts when they feel they need to do so. Their body image becomes a constant struggle, as they may or may not acknowledge that they are too thin or underweight; they will deny it is a problem, but rather claim it is a choice.

Introverted personality Keep in mind, however, that patients may also be active in social and school circles and may be accomplished individuals. Previous Next Done estimated finish: 30min left Overview of Eating Disorders / Anorexia Nervosa Behaviors: Objective Data Altered eating patterns are the most recognizable method that those with anorexia nervosa use to control their weight. There are two types of eating behaviors utilized: restriction of food or purging (vomiting) of food. Restrictors Those who restrict their food are typically in the normal weight range for their body type, or slightly above. Restrictors feel that by eating below their daily required caloric needs, their weight loss will occur faster and more steadily. Restrictors will often avoid social settings where food is consumed, or eat minimally. Those with anorexia nervosa who use food restriction as their method of weight loss will often: Withdraw from family and friends Become intense and overly competitive during activities Exercise excessively Appear anxious Be restless and unable to sleep

Vomiters-Purgers Those who purge and vomit their food typically start at a higher weight, and are likely considered obese prior to the anorexia nervosa disease beginning. These individuals use several methods to achieve weight loss, such as use of diuretics, laxatives, and vomiting. They eat normally in social situations, but will soon purge their food after consumption. Binging on food is also a characteristic of these individuals, due to the dietary restrictions they place upon themselves and, uncontrollable eating occurs with purging afterward.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
