Symptoms of bulimia may be difficult for friends and family to detect, as many patients with bulimia are high functioning and may not appear to be overweight and are often a healthy weight. However these patients often hide the bulimic behavior.
Those suffering from bulimia nervosa will binge on a large amount of food and feel shame which results in the need to purge the food to prevent weight gain. They will force themselves to vomit, exercise excessively, or use diet pills and laxatives. The cycle can repeat several times a week, and in severe cases, several times a day.
