Document Summary
Chapter 9: eating disorders and obesity: eating disorders- characterized by a persistent disturbance in eating behavior, anorexia and bulimia- central to both disorders an intense fear of becoming overweight and fat and an accompanying pursuit of thinness. Followed by efforts to purge, or remove from their bodies, the food that they have eaten. Methods of purging commonly include self-induced vomiting or misusing laxative, diuretics, and enemas. Binge eating disorder: binge eating disorder- frequent episodes of binge eating, typically overweight or obese, no compensatory weight loss behaviors. Age of onset and gender differences: anorexia nervosa- most likely to develop in 15-19 year olds, bulimia nervosa- most likely to develop in women ages 20-24, three females for every male with an eating disorder. Medical complications of eating disorders: anorexia can lead to death from heart arrhythmias, kidney damage, and renal failure, bulimia can lead to electrolyte imbalances, hypokalemia (low potassium), and damage to hands, throat, and teeth.
