Bulimia Nervosa & Compulsive Overeating
Introduction What are Eating Disorders? Bulimia Nervosa – 1.)eating in secrecy any amount of food that is a larger portion than a normal person would eat. It usually lasts less than two hours. There is a lack of control of eating during the episodes. The person is literally unable to stop eating or control what is eaten and how much is consumed. Continual snaking throughout the day is not considered would not be considered binging. 2.) The person induces vomiting in order to prevent weight gain. Along with vomiting one may also misuse laxatives, diuretics, enemas, or others medications. They may also fast or do an excessive amount of exercise. 3.) In order to qualify for diagnosis one must engage in the behaviors for at least twice a week for 3 months
Introduction Binge Eating: Consumption of large amounts of food in a short period of time Other: mainly Anorexia Nervosa but there have been more forms classified lately.
How do I know if someone has an eating disorder? Signs of Bulimia: Dramatic weight loss in a relatively short period of time. Wearing big or baggy clothes or dressing in layers to hide body shape and/or weight loss. Obsession with weight and complaining of weight problems (even if "average" weight or thin). Obsession with calories and fat content of foods. Isolation. Fear of eating around and with others. Unusual Food rituals such as shifting the food around on the plate to look eaten; cutting food into tiny pieces; making sure the fork avoids contact with the lips (using teeth to scrap food off the fork or spoon); chewing food and spitting it out, but not swallowing; dropping food into napkin on lap to later throw away. Hiding food in strange places (closets, cabinets, suitcases, under the bed) to avoid eating (Anorexia) or to eat at a later time. Hair loss. Pale or "grey" appearance to the skin. Dizziness and headaches. Low blood pressure. Loss of menstrual cycle. Constipation or incontinence.

DSM-IV Diagnostic Criteria Bulimia Nervosa: 1. Defined by recurrent episodes of binge eating 2. Self induced vomiting 3. Occurs at least twice a week for 3 months 4. Self- evaluation 5. Does not occur exclusively during episodes of Anorexia Nervosa
DSM-IV Diagnostic Criteria continued Purging type: Self induced vomiting or misuse of laxatives or other medications Nonpurging type: Person fasts and exercises excessively and does not partake in self- induced vomiting or misuse laxatives or other medications
Prevalence Rate -About 1 in every 181 in the US are affected by bulimia nervosa -Binge eating disorder affects % of the general population -Binge eating usually occurs during or after a period of dieting
Environmental Causes Family Dynamics Social Factors Cultural Pressures The Media
Genetic Causes Eating Disorder behaviors are a symptom of underlying emotional distress. Parents can add a lot of pressure on a child to excel by setting high standards and negative emotions are taught to be suppressed. In keeping with these high standards, people with eating disorders strive to be model students and lead perfect lives. Biological factors that are associated with clinical depression can lead to the development of bulimia nervosa Studies have shown an increased frequency of eating disorders if they are present in first degree biological relatives
Societies Impact Thought to be around middle and upper classes Not completely trueincreasing numbers of cases are seen in all types of classes A studies results showed that Anorexia Nervosa was predominant in higher classes while bulimia was distributed consistently throughout all classes Most prevalent in industrialized countries Western Vs. Nonwestern Medscape's General Medicine 6(3) 2004, prevalence rates in Western countries for anorexia nervosa ranged from 0.1% to 5.7% in female subjects. Prevalence rates for bulimia nervosa ranged from 0% to 2.1% in males and from 0.3% to 7.3% in female subjects. Prevalence rates in non-Western countries for bulimia nervosa ranged from 0.46% to 3.2% in female subjects. Studies of eating attitudes indicate abnormal eating attitudes in non- Western countries have been gradually increasing, presumably because of the influence, at least in part, of Western media: movies, TV shows, and magazines. Researchers conclude that the prevalence of eating disorders in non-Western countries is lower than that of Western countries, but it appears to be increasing.
Diversity: Race Over the past few years there has been increasing evidence of disordered eating occurring among racial and ethnic minorities in the U.S. Contrary to the persistent belief that eating disorders affect only young white women. A study found that dieting was associated with weight dissatisfaction, perceived overweight, and low body pride in all ethnic groups. African American girls may be especially vulnerable to develop a binge eating disorder African American girls age scored higher on the Eating Disorder Inventory than most white females. This scale measures features commonly associated with eating disorders. A telephone survey found that African American women were just as likely as white women to report binge eating Studies have also shown binge eating to be the most severe in Hispanics
Diversity: Age 2-3% of females affected by the illness are late adolescent to early adulthood Lifetime prevalence in females is 1-3% Incidence and prevalence has increased in all age groups Prevalence is increasing among pre-pubertal girls A study has shown that 70% of sixth grade girls first became worried about their weight at age 9 Eating disorders mainly affect people in their teens and twenties, but studies have reported children as young as 6 and individuals as old as 76! As baby-boomers in the U.S. grow older, there seems to be an increase in incidence of middle-aged women with an eating disorder, possibly because this group has consistently considered image to be of major importance. In the U.S. the lifetime prevalence of bulimia is reportedly 3%. Bulimia Nervosa affects about 6% of adolescent girls and 5% of college women.
Diversity: Gender Prevalence of bulimia nervosa in females is 1.1 to 4.2% The prevalence rate in males is one tenth of that of females 5-15% of cases of eating disorders involve men in the US 85-95% of cases of eating disorders are among women in the US Binge eating is prominent in females to males with a 3:2 ratio
The Good, the Bad, the Ugly Positives Initial weight loss can improve athletic performance Temporary positive feedback from friends, coaches, and family. Gives a false sense of control Gives temporary relief to anxiety Negative Heart problems Threat of Female Triad Muscle deterioration Imbalance electrolytes Dehydration Kidney Problems Mood swings Depression Isolation Death ………..and the list goes on and on
Treatment The treatment team that usually consists of a Dietitian, Psychiatrist, and a Physician There are also treatment facilities available but good ones are hard to find around the U.S. ***One of the major ongoing debates with treatment of an eating disorder is that most insurance will not cover it. This puts families in a hard position if they cannot afford the treatment****
Community Programs Get Help! There are MANY treatment facilities in Alabama The Medical Center in Auburn University
Recovery With treatment 60% fully recover 40% still struggle Without treatment, up to 20% of people with serious eating disorders die. That number falls to 2-3% with treatment!!!
