Document Summary
Key factors restriction of food intake, leading to a significantly low body weight for age, health, and gender. Disturbance in the way individuals experience their body weight or shape. Brain changes (abnormal cortisol, dopamine, serotonin, norepinephrine levels) Return to normal eating behaviors takes a long time. Rigid diet that lasted from several weeks to a year or more. Regular reliance on self-induced vomiting, laxative or diuretics. Minimum of one bingeing episode per week for at least three months. American adults have been eating steadily more calories for almost a decade, accounting for the continued increase in obesity rates. A hormone called leptin, produced by fat cells, sends signals that regulate appetite to the brain. Continuing to eat even when you are no longer hungry is a sign of compulsive overeating. People with purging bulimia induce vomiting or take large doses of laxatives to relieve guilt and control their weight.
